Gary Kildall
Gary Arlen Kildall (/ˈkɪldɔːl/; May 19, 1942 – July 11, 1994) was an American computer scientist and microcomputer entrepreneur. During the 1970s, Kildall created the operating system CP/M among other operating systems and programming tools, and subsequently founded Digital Research, Inc. to market and sell his software products. He is considered a pioneer of the personal computer revolution.
In 1974 in Pacific Grove, California, Kildall demonstrated the first working prototype of CP/M, which would later become the dominant operating system for microcomputers for a time. Together with his invention of the BIOS (Basic Input Output System), his operating system allowed a microprocessor-based computer to communicate with disk storage. Kildall was among the earliest individuals to recognize microprocessors as fully capable computers. During the 1980s, Kildall also appeared on PBS as co-host of Computer Chronicles, a weekly informational program that discussed the latest developments in personal computing.
Gary Kildall was born and grew up in Seattle, Washington, where his family operated a seamanship school. His father, Joseph Kildall, was a captain of Norwegian heritage. His mother Emma was of half Swedish ancestry, as Kildall's grandmother was born in Långbäck, Sweden, in Skellefteå Municipality, but emigrated to Canada at 23 years of age.
Kildall earned a bachelor's degree in mathematics in 1967 and a master's degree in Computer Science in 1968, both from the University of Washington. At one time, he had hoped to become a mathematics teacher. During his studies, Kildall became increasingly interested in computer technology and enrolled to attain a Ph.D. in Computer Science.
Kildall fulfilled his draft obligation by teaching at the Naval Postgraduate School in Monterey, California.
Kildall briefly returned to UW and finished his doctorate in computer science in 1972.
Intel lent him systems using the 8008 and 8080 processors, and in 1973, he developed the first high-level programming language for microprocessors, named PL/M. For Intel he also wrote 8008 and 8080 instruction set simulators named INTERP/8 and INTERP/80. He created the operating system CP/M the same year to enable the 8080 to control a floppy disk drive, combining for the first time all the essential components of a computer at the microcomputer scale. He demonstrated CP/M to Intel, but Intel had little interest and chose to market PL/M instead.
In 1973 Kildall and Kathryn Strutynski developed the language PL/M to produce CP/M, one of the first operating systems for personal computers.They used as reference their experience with the IBM mainframe computers and the operating system VM.
