Andrew Donald Booth (11 February 1918 – 29 November 2009)[2][3] was a British electrical engineer, physicist and computer scientist who was an early developer of the magnetic drum memory for computers.[1] He is known for Booth's multiplication algorithm.[2] In his later career in Canada he became president of Lakehead University.

Key Information

Early life

[edit]

Andrew Donald Booth was born on February 11, 1918, in East Molesy, Surrey, UK.[4] He was the son of Sidney Booth (died 1955) and a cousin of Sir Felix Booth.

He was raised in Weybridge, Surrey, and educated at Haberdashers' Aske's Boys' School. In 1937, he won a scholarship to read mathematics at Jesus College, Cambridge. Booth left Cambridge without taking a degree, having become disaffected with pure mathematics as a subject. He chose an external degree from the University of London instead, which he obtained with a first.[2]

Career

[edit]

From 1943 to 1945, Booth worked as a mathematical physicist in the X-ray team at the British Rubber Producers' Research Association (BRPRA), Welwyn Garden City, Hertfordshire, gaining his PhD in crystallography from the University of Birmingham in 1944. In 1945, he moved to Birkbeck College, University of London, where his work in the crystallography group led him to build some of the first electronic computers in the United Kingdom[5][6] including the All Purpose Electronic Computer, first installed at the British Rayon Research Association.[7] Booth founded Birkbeck's department of numerical automation and was named a fellow at the university in 2004.[8] He also did early pioneering work in machine translation.[9]

After World War II, he worked on crystallographic problems research at Birkbeck College and constructed a Fourier synthesis device. He was then introduced to the work of Alan Turing and John von Neumann on logical automata by Douglas Hartree.[4]

The first assembly code in which a language is used to represent machine code instructions is found in Kathleen and Andrew Donald Booth's 1947 work, Coding for A.R.C..[10] Assembly code is converted into executable machine code by a utility program referred to as an assembler. The term "assembler" is generally attributed to Wilkes, Wheeler and Gill in their 1951 book The Preparation of Programs for an Electronic Digital Computer,[11] who, however, used the term to mean "a program that assembles another program consisting of several sections into a single program".[12] The conversion process is referred to as assembly, as in assembling the source code. The computational step when an assembler is processing a program is called assembly time.

Booth served as President of Lakehead University from 1972 to 1978.

Personal life

[edit]

Booth married mathematician and computer engineer Kathleen Britten in 1950, and had two children, Amanda and Ian;[13] between 1947 and 1953, together they produced three computing machines.

Booth directed Birkbeck's Electronic Computer Project from 1950 to 1955 and founded its Computation Laboratory in 1957, which evolved into the Department of Numerical Automation and offered the UK's first MSc in that field. In 1962, he relocated to Canada as Professor and Head of Electrical Engineering at the University of Saskatchewan, before serving as President of Lakehead University in Thunder Bay, Ontario, from 1972 to 1978, where he established the institution's first graduate programs amid financial challenges. His artifacts, including the original magnetic drum, are preserved in collections like the Science Museum Group.

Early Life and Education

Early Years

Andrew Donald Booth was born on 11 February 1918 in , . He grew up in in a family with strong ties to engineering and medicine. His father, descended from a long line of engineers and shipbuilders, had served as commander of a during and later worked on innovative projects like automatic ignition advances for motor cars. Booth's mother came from a family of medical doctors, pursued interests in music as an accomplished pianist and , and had worked as a nurse during the war. From an early age, Booth was immersed in his father's engineering world, which sparked his scientific curiosity. As an infant, he was told exciting stories of maritime engineering challenges, such as the loss of rudders and propellers on ships. In his years, he assisted his father in assembling a mains charger for radio batteries using nickel-copper thermoelectric junctions and became fascinated by detailed engineering drawings. His parents actively encouraged this inquisitiveness, fostering an environment that valued hands-on experimentation. Booth's childhood unfolded during the , marked by vivid early memories amid Britain's post-World War I recovery. His earliest recollection, from around nine months old, was a family outing to the theater on Armistice Night in , where he remembered the brass band, red plush curtains, and brass rail—details later confirmed by his parents. By age two, he demonstrated an innate grasp of practical physics by mimicking his father's repair of a blown fuse, inadvertently connecting to the 240-volt mains and startling the family's . These formative experiences laid the groundwork for his later interests in and physics, though his initial formal exposure to math was limited until paternal tutoring improved his proficiency. He was educated at Haberdashers' Aske's Boys' School in , .

Academic Training

Booth began his higher education in 1937 with a scholarship to study at . However, he departed without completing a degree, influenced by a growing disaffection with and the disruptions of . Instead, Booth pursued an external degree in from the , which he earned in 1940 with first-class honors. This qualification marked his foundational training in physics, setting the stage for his later specialization. Booth then shifted focus to , enrolling at the where he completed a PhD in chemistry in 1944. His thesis centered on the application of techniques to determine structures, particularly of materials relevant to wartime needs. During his doctoral studies, Booth became involved in early efforts to support crystallographic computations, designing and building three small analog computers in that aided in these calculations. This hands-on work foreshadowed his future innovations in hardware. From 1943 to 1945, Booth applied aspects of his PhD research as a mathematical in the team at the British Rubber Producers' Research Association.

Scientific and Computing Career

Crystallography and Early Computing

Following his academic training, Andrew Donald Booth joined the British Rubber Producers' Research Association (BRPRA) in as a mathematical in the team from 1943 to 1945. There, he applied to analyze the molecular structure of rubber materials, a critical effort amid wartime demands for improved synthetic alternatives to . This work built directly on his PhD research at the , where he had earned a in 1944 on the of explosive materials, supported by a BRPRA . During , Booth's involvement in crystal structure determination using diffraction data highlighted the limitations of manual computation. The process required extensive hand calculations of to interpret diffraction patterns and reconstruct atomic arrangements, a repetitive and time-intensive task that he described as "no fit occupation for a gentleman." To address this, Booth designed three small analog computing devices during his graduate studies, extending from his PhD work, which automated aspects of these calculations and proved valuable to crystallographers by accelerating the synthesis of electron density maps from data. These machines, detailed in his 1945 publication, represented his initial foray into automatic calculators tailored for scientific computation in . Booth's experiences underscored the broader need for computational aids in scientific research, particularly for handling the repetitive arithmetic inherent in analysis and similar fields. He recognized that electronic devices could transform such labor by performing rapid, accurate iterations, freeing researchers for interpretive work. Motivated by this, Booth resolved to pursue machine-based solutions in an academic setting, leading him to join Birkbeck College in 1945.

Work at Birkbeck College

Andrew Donald Booth joined Birkbeck College, , in as a in , where he initially focused on crystallographic research under the guidance of . His work there emphasized the of complex calculations needed for scientific analysis, building on his wartime experience with determination. In 1957, Booth founded the Department of Numerical Automation at Birkbeck, aimed at harnessing early technology for analysis through and other scientific challenges. As head of this department from 1955 to 1962, he directed efforts to integrate into academic research, fostering applications beyond physics into broader interdisciplinary problems. Booth held the position of Professor of Physics and provided leadership for computing initiatives at Birkbeck until 1962, when he departed for academic opportunities in Canada. The collaborative environment he cultivated involved assembling a compact of research assistants and students to advance computer development, enabling hands-on experimentation with limited resources in a resource-constrained postwar setting. Under his guidance, the group constructed early machines like the ARC and APEC to support crystallographic and computations. In recognition of his foundational role in establishing computing at the institution, Booth was appointed a Fellow of Birkbeck College in 2003.

Key Contributions to Computing

Computer Designs and Hardware Innovations

Andrew Donald Booth's early hardware innovations centered on electromechanical and electronic devices developed at Birkbeck College, , where he addressed the computational needs of crystallographic research. Between 1947 and 1949, Booth designed and built the Automatic Relay Computer (ARC), a relay-based machine that marked one of the first practical computers in the . The ARC utilized approximately 1,000 relays for logic operations and paper tape for input, enabling it to perform basic arithmetic and handle Fourier transforms essential for analysis. Its architecture emphasized reliability over speed, with operations executed sequentially under programmed control, making it suitable for scientific . A key innovation in the ARC was Booth's development of magnetic drum memory, which he constructed in 1947–1948 as a compact, rotating storage solution to overcome limitations of punched cards and relays. This device, a two-inch diameter cylinder coated with iron oxide, stored data magnetically at a density of 10 bits per inch and rotated at 3,000 rpm to allow rapid access for instructions and results—representing the first such implementation in a UK computer. The drum provided non-volatile retention of up to 32 tracks, each holding short programs or data sets, and integrated directly with the ARC's relay logic to function as both main memory and backing store. This technology proved pivotal for early machines, enabling persistent data handling without constant mechanical intervention. In collaboration with his wife, (née Britten), Andrew Booth constructed three computing machines between 1947 and 1953, progressing from electromechanical to fully electronic designs. The first was the ARC, followed by the Simple Electronic Computer (SEC) in 1948–1950 as an electronic prototype (a planned relay-based ARC2 redesign was abandoned in favor of ). By 1952, they developed the All-Purpose Electronic Computer (APEC), also known as the APE(X)C or All-Purpose Electronic X-ray (APEX), a stored-program shifting to () for faster execution. The APE(X)C featured 32-bit words, a 32-track magnetic for 1,024-word memory capacity, and plugboard programming, allowing general-purpose calculations beyond , such as numerical simulations. Built in a barn at the Booths' family home due to space constraints at Birkbeck, it demonstrated electronic viability for small-scale scientific with around 100 . Booth's designs influenced commercial hardware, notably the Hollerith Electronic Computer (HEC) series produced by the British Tabulating Machine Company starting in 1951. The HEC-1 prototype adapted the ARC's relay architecture and magnetic drum principles for business applications, integrating with punched-card systems for in and . This led to mass-produced variants like HEC-2 and HEC-4, which retained Booth's storage innovations while scaling for industrial use, marking an early bridge from academic prototypes to commercial viability.

Algorithms and Software Developments

Andrew Donald Booth made significant contributions to early computing through innovative algorithms and software techniques that enhanced computational efficiency and accessibility. His work laid foundational elements for programming languages and automated processes, particularly in the context of limited hardware resources during the post-World War II era. Booth's developments emphasized practical methods for handling complex operations like and translation, influencing subsequent advancements in . In 1947, Booth, in collaboration with , developed the first known as part of their work on the Automatic Relay Computer (ARC) at Birkbeck College. This system, detailed in their report Coding for A.R.C., introduced a symbolic representation of instructions to simplify programming the electromechanical ARC machine, which used relays for computation. By mapping mnemonic codes to binary instructions, it reduced the tedium of direct machine coding and improved error detection, marking an early step toward higher-level abstractions in . This assembly code allowed programmers to write instructions in a more human-readable form before assembling them into executable binary, a concept that became standard in later computers. Booth's pioneering efforts in began with concepts developed in 1946 in collaboration with Warren Weaver. Building on these ideas, in 1948 he collaborated with Richard H. Richens of the Cambridge Language Research Unit on early experiments using punched cards to mechanize bilingual dictionaries, focusing initially on morphological analysis. Their work evolved to incorporate semantic approaches by 1952, as outlined in Some Methods of Mechanized Translation, where they proposed encoding word meanings through relational networks to handle context beyond simple word-for-word substitution. This semantic analysis aimed to address ambiguities in , with examples applied to English-Russian translation using a restricted vocabulary of 250 words and basic grammar rules for 49 sample sentences. Their 1955 demonstration at Birkbeck College translated short Russian texts into English, showcasing the feasibility of computer-assisted semantic processing despite limitations in hardware speed. These innovations emphasized rule-based systems and dictionary mechanization, influencing the field's shift toward . Booth's most enduring algorithmic contribution is the Booth multiplication algorithm, invented in 1951 while researching crystallography at Birkbeck College. Published in A Signed Binary Multiplication Technique, this method efficiently multiplies two signed binary numbers in two's complement notation by reducing the number of addition operations required, particularly for strings of consecutive 1s in the multiplier. Unlike standard binary multiplication, which adds the multiplicand for every 1 bit, Booth's algorithm scans the multiplier from the least significant bit (LSB) to the most significant bit (MSB), examining pairs of bits (the current bit and the previous one, starting with an implicit 0 before the LSB). It performs arithmetic operations based on bit transitions to exploit patterns in the binary representation: adding the multiplicand shifted left by the current position when transitioning from 0 to 1 (end of a 0-run), subtracting it when transitioning from 1 to 0 (start of a 0-run), and doing nothing for 00 or 11 pairs (middle of 0- or 1-runs). After each operation, the partial product is arithmetically right-shifted to align bits. This approach minimizes partial additions/subtractions—often halving them for typical multipliers—and handles signed numbers seamlessly without separate positive/negative cases. The algorithm's , as derived from Booth's original technique, can be expressed as follows for multiplying multiplicand MM (n bits) by multiplier QQ (n bits), producing a 2n-bit product PP:

Initialize: A = 0 (accumulator, n bits), Q = multiplier (n bits), Q_{-1} = 0 (extra bit) For i = 1 to n: If Q_0 Q_{-1} == 01: // End of 0s (add) A = A + M Else if Q_0 Q_{-1} == 10: // Start of 0s (subtract) A = A - M // Else (00 or 11): No operation // Arithmetic right shift: A || Q = (A || Q) >> 1, with [sign extension](/page/Sign_extension) into A MSB Q_{-1} = Q_0 // Update extra bit; shift Q right, bringing in Q_{-1} as new Q_0? Wait, standard: shift A right, Q right, Q_{-1} = old Q_0 Product P = A || Q // Concatenate for final 2n-bit result

Initialize: A = 0 (accumulator, n bits), Q = multiplier (n bits), Q_{-1} = 0 (extra bit) For i = 1 to n: If Q_0 Q_{-1} == 01: // End of 0s (add) A = A + M Else if Q_0 Q_{-1} == 10: // Start of 0s (subtract) A = A - M // Else (00 or 11): No operation // Arithmetic right shift: A || Q = (A || Q) >> 1, with [sign extension](/page/Sign_extension) into A MSB Q_{-1} = Q_0 // Update extra bit; shift Q right, bringing in Q_{-1} as new Q_0? Wait, standard: shift A right, Q right, Q_{-1} = old Q_0 Product P = A || Q // Concatenate for final 2n-bit result

An illustrative example is multiplying 2 (001020010_2, MM) by -3 (110121101_2, QQ, 4 bits):
  • Initial: A = 0000, Q = 1101, Q_{-1} = 0
  • Step 1 (Q_0=1, Q_{-1}=0 → 10): A = 0000 - 0010 = 1110, then arith shift A||Q=11101101 → 11110110 (A=1111, Q=0110), Q_{-1}=1
  • Step 2 (Q_0=0, Q_{-1}=1 → 01): A = 1111 + 0010 = 0001 (mod 16), shift 00010110 → 00001011 (A=0000, Q=1011), Q_{-1}=0
  • Step 3 (Q_0=1, Q_{-1}=0 → 10): A = 0000 - 0010 = 1110, shift 11101011 → 11110101 (A=1111, Q=0101), Q_{-1}=1
  • Step 4 (Q_0=1, Q_{-1}=1 → 11): No op, shift 11110101 → 11111010 (A=1111, Q=1010? Wait, correct shift: 1111 0101 >>1 =1111 1010 (A=1111, Q=1010), but standard yields low 4=1010=-6 unsigned? Final A||Q=11111010 = -6 in 8-bit two's (invert 00000101+1=6, negative).
This method's efficiency stems from fewer operations (e.g., two adds/subtracts here vs. three in standard), making it suitable for hardware implementation despite the era's computational constraints.

Later Career and Administration

Leadership at Birkbeck

In 1945, Andrew Donald Booth joined Birkbeck College as a researcher in J.D. Bernal's physics department, where he later assumed the Chair of Physics, leading efforts to integrate into crystallographic studies. Under his , the college's computing facilities expanded significantly, evolving from rudimentary electromechanical devices to dedicated electronic systems that supported advanced in physics and related fields. This growth culminated in the establishment of the Electronic Computation Laboratory in the early , which was formalized as the Department of Numerical Automation in 1957—the first such department in a British university—fostering a dedicated research group focused on computational methods for scientific applications. Booth played a pivotal role in securing external funding and forging collaborations to sustain these initiatives. He obtained grants from the in 1947 to support computational projects, including early explorations in , and additional funding from the British Rubber Producers' Research Association to address crystallographic challenges. These resources enabled partnerships with industry leaders, such as the British Tabulating Machine Company, which helped transition academic prototypes into practical tools and broadened the scope of Birkbeck's computing efforts through shared expertise and resources. As head of the Department of Numerical Automation, Booth mentored a generation of students and researchers in and , co-authoring influential texts on digital calculators with his collaborator . His guidance emphasized interdisciplinary applications, drawing from his own experience under Bernal, and helped build a team that advanced automated methods in scientific computation. By the late and into the , Booth transitioned from direct hardware development to broader departmental oversight, serving as director of the computer project while prioritizing administrative expansion and strategic funding to position Birkbeck as a hub for computational innovation. In 1962, Booth left Birkbeck to join the in as Professor and Head of the Department of , a position he held until 1972.

Presidency at Lakehead University

In 1972, Andrew Donald Booth relocated from the University of Saskatchewan to , , where he was appointed as the second president of , serving from 1972 to 1978. His earlier expertise in informed his vision for advancing the institution's academic profile during this period. During his presidency, Booth prioritized modernization efforts, particularly the establishment of Lakehead's first graduate programs to foster a research-oriented culture. He expanded offerings in science and computing, aligning with the university's growth needs and his own background in these fields, while introducing innovative initiatives like the "bright kids" program, which allowed promising high school students to take free university-level courses with credits banked for future enrollment. Booth's tenure was marked by significant challenges amid the 1970s economic climate, including provincial funding cuts, declining student enrollment, and a financial deficit he inherited upon arrival. As he later recalled, "this illusion [of a thriving institution] was rapidly dispelled when Grant Thompson… asked me what I proposed to do about the deficit!" Provincial government-driven economic measures further hindered progress on graduate program development. Following his resignation in 1978, Booth retired from full-time academia but took on the role of chair at Autonetics Research Associates in British Columbia, Canada, continuing consulting and research activities until his later years.

Personal Life and Collaborations

Family and Marriage

Andrew Donald Booth married Kathleen Hylda Valerie Britten (later known as Kathleen Booth) in 1950, shortly after she completed her PhD in applied mathematics at the University of London. The couple had two children: Amanda Booth, born in March 1962 and who became a veterinarian, and Ian J. Booth, who pursued a career as a physicist. Booth's family initially resided in London, where he worked at Birkbeck College, before relocating to Canada in 1962; they lived in Saskatoon, Saskatchewan, during his tenure at the University of Saskatchewan, and later in Thunder Bay, Ontario, while he served as president of Lakehead University from 1972 to 1978. In 1978, Booth and his wife retired to Sooke, British Columbia, where they enjoyed a quiet life near the coast. Their shared interest in science fostered a family environment that encouraged intellectual pursuits among their children. In his personal time, Booth maintained a lifelong passion for , having practiced the intensively in his youth under the tutelage of violinist Carl Flesch, though he ultimately chose a career in science over music. Booth passed away peacefully on November 29, 2009, at the age of 91 in a hospital in Victoria, British Columbia; he remained mentally sharp until the end, as noted by his daughter Amanda, and was survived by his wife of nearly 60 years, Kathleen, and their two children. Kathleen Booth died on September 29, 2022, in Sooke, British Columbia, at the age of 100.

Partnership with Kathleen Booth

Kathleen Booth, née Britten, joined Andrew Donald Booth at Birkbeck College in 1946 as a in and soon became a key collaborator in his endeavors, serving as both assistant and co-designer on early projects. Their professional partnership, which deepened after their marriage in 1950, focused on developing practical systems for scientific applications, particularly in . Together, they contributed to the design and construction of the Automatic Relay Computer (ARC) in 1947, a relay-based machine with magnetic drum storage capable of handling 256 words of 21 bits each, where Kathleen played a central role in assembly alongside colleague Xenia Sweeting. From 1947 to 1953, the Booths jointly built three computing machines: the ARC, the Simple Electronic Computer (SEC) around 1950, and the All-Purpose Electronic Computer (APEX), a stored-program machine with 32-bit precision and 1-kiloword , operational by late 1952. In these efforts, they co-authored foundational reports, including Coding for A.R.C. (1947), which outlined programming methods, and General Considerations in the Design of an All-Purpose Electronic Digital Computer (1947), influencing stored-program architectures. Their collaboration extended to developing early elements; Kathleen independently invented an system for the ARC2 variant and wrote its assembler, making programming more accessible for non-experts. Kathleen's independent contributions further enriched their joint work, particularly in programming and magnetic storage refinements, where she co-developed the first rotating magnetic drum device—a compact 2-inch diameter unit storing 10 bits per inch—that became a model for mass-produced systems by Wharf Engineering Co. She also authored Programming for an Automatic Digital Calculator (1958), detailing techniques for their machines. This partnership significantly advanced and early software tools; at Birkbeck, Kathleen directed programs, culminating in a public demonstration of French-to-English on , 1955, while their integrated hardware-software approach facilitated simulations for in the 1950s, laying groundwork for and AI applications. Their co-authored Automatic Digital Calculators (1953) synthesized these innovations, emphasizing practical programming and design principles that influenced subsequent British computing developments.

Legacy and Recognition

Impact on Computer Science

Andrew Donald Booth's multiplication algorithm, introduced in 1951, remains a cornerstone in efficient binary arithmetic, particularly for signed numbers in representation. This method reduces the number of partial products by encoding the multiplier to skip redundant additions, enabling faster hardware implementations. Today, variants of the Booth algorithm are integral to (DSP) applications, where high-speed multiplication is essential for tasks like filtering and Fourier transforms in embedded systems and devices. It is widely adopted in modern hardware multipliers within processors and FPGAs, optimizing power and area efficiency in resource-constrained environments such as and real-time signal analysis. Booth's pioneering work on in the mid-1940s addressed the critical need for reliable, high-capacity storage in early computers, constructing one of the first practical devices capable of holding 10 bits per inch. This innovation influenced subsequent developments in rotating , serving as a direct precursor to -based systems in commercial computers and eventually contributing to the evolution of hard disk drives by demonstrating scalable, non-volatile data retention. His designs, integrated into machines like the Automatic Relay Computer (ARC), paved the way for affordable secondary storage solutions that enabled broader computational experimentation in academic settings. In the realm of , Booth's early experiments in during the late 1940s, including collaborations on morphological analysis and mechanical dictionaries using punch-card systems, established foundational techniques for automated language processing. These efforts, detailed in the 1955 anthology , highlighted the potential of computers for linguistic tasks beyond numerical computation, influencing the emergence of as a discipline. By applying computing to problems, Booth's work laid groundwork for later AI advancements in syntax parsing and semantic representation. Booth holds a pivotal place in UK computing history as one of the "fourth man" among pioneers, alongside Alan Turing's theoretical foundations, ' Colossus hardware, and ' EDSAC implementation, for his practical advancements in accessible at Birkbeck College. His leadership in building low-cost, university-scale machines democratized access to computing resources, fostering in a era with limited funding and inspiring subsequent generations of British computer scientists.
