Sir Edward Penley Abraham, CBE, FRS[3] (10 June 1913 – 8 May 1999) was an English biochemist instrumental in the development of the first antibiotics penicillin and cephalosporin.[4][5]

Key Information

Early life and education

[edit]

Abraham was born on 10 June 1913 at 47 South View Road, Shirley, Southampton. From 1924 Abraham attended King Edward VI School, Southampton, before achieving a First in Chemistry at The Queen's College, Oxford.[6]

Abraham completed his DPhil at the University of Oxford under the supervision of Sir Robert Robinson, during which he was the first to crystallise lysozyme,[1][7] an enzyme discovered by Sir Alexander Fleming and shown to have antibacterial properties, and was later the first enzyme to have its structure solved using X-ray crystallography, by Lord David Phillips.[8]

Research

[edit]

In 1938 Abraham won a Rockefeller Foundation travel fellowship and spent a year in Stockholm at the Biokemiska Institut.[9]

He then moved back to Oxford and became part of a research team led by Sir Howard Florey at the Sir William Dunn School of Pathology, responsible for the development of penicillin and its medical applications. Abraham was specifically involved in the purification process and determination of its chemical structure. In 1940 Abraham discovered penicillinase as the cause of bacterial resistance to antibiotics such as penicillin.[10] In October 1943 Abraham and Sir Ernst Boris Chain proposed a novel beta-lactam structure with a fused two ring system.[11][12] This proposal was confirmed in 1945 by Dorothy Hodgkin using X-ray crystallography.[12][13] Florey formally recognised Abraham's work in 1948 by nominating him to be one of the first three "penicillin" research Fellows at Lincoln College, Oxford.

Later that year samples of a Cephalosporium acremonium fungus with antibacterial properties were received from Giuseppe Brotzu.[14] Abraham and Guy Newton purified the antibiotics from this fungus and found one, cephalosporin C, was not degraded by penicillinase and hence able to cure infections from penicillin-resistant bacteria.[15][16] During a skiing holiday in 1958 Abraham conceived the structure of cephalosporin C,[17] which he then went on to establish with Newton,[18] and was confirmed by Dorothy Hodgkin through X-ray crystallography.[19] Abraham showed that modification of the 7-amino-cephalosporanic acid nucleus was able to increase the potency of this antibiotic[20][21] and registered a patent on the compound.[11] This resulted in the first commercially sold cephalosporin antibiotic Cefalotin sold by Eli Lilly and Company. There are now five generations of cephalosporins, of which some are among the few remaining antibiotics for the treatment of MRSA.

In 1964 he became Professor of Chemical Pathology, and remained a Fellow of Lincoln until his retirement in 1980.[5]

Personal life

[edit]

Abraham was born at 47 South View Road, Shirley, Southampton.[11] His parents were Maria Agnes Abraham, née Hearne and Albert Penley Abraham, a customs and excise officer.

In 1938 he met Asbjörg Harung from Norway whom he married in Bergen the following year: she remained in Norway, trapped by the German invasion, before escaping to Sweden in 1942 when she was reunited with her husband.[22] They had a son Michael Erling Penley Abraham, born in Oxford in July 1943.[11][23]

Edward Abraham died in May 1999, in Oxford, following a stroke. He was survived by his wife, Asbjörg.[24]

Sir Edward and Lady Abraham lived at Badgers Wood, Bedwells Heath, Boars Hill, where part of the land, Abraham Wood is now managed by the Oxford Preservation Trust.[25]

Legacy

[edit]

He was a noted biochemist, his work on antibiotics producing great clinical advances. His principal work was concerned with the development of penicillin, and also later cephalosporin, an antibiotic capable of destroying penicillin-resistant bacteria. These vital drugs are now used extensively in the treatment of various infections, including pneumonia, bronchitis, septicaemia and infected surgical wounds.

Through the registration of the patent on cephalosporin, he was able to generate a regular income, which he devoted almost entirely to the establishment of two charitable trusts for the support of biomedical research, the Edward Penley Abraham Research Fund,[26] the E.P.A. Cephalosporin Fund[27] and The Guy Newton Research Fund.[28] As of 2016 the combined endowment of these charities is over £194 million. By the end of the twentieth century, the charitable funds had donated more than £30m to the University of Oxford, mainly to the Dunn School of Pathology and to Lincoln College, along with other grants to The Royal Society and King Edward VI School, Southampton. Four recent Oxford buildings received funds from Abraham's trusts:

  • the EP Abraham research building[6][29] (completed in 2001, on South Parks Road)
  • Lincoln College's EPA Science Centre (an accommodation and conferencing complex, including Lady Abraham House, completed in 2005, on Museum Road),[30]
  • Linacre College's Edward & Asbjörg Abraham Building (completed in 1995)[31]
  • The Oxford Molecular Pathology Institute, completed in 2011, is also largely funded by proceeds from Abrahams patents.[32]

Funding from these trusts have also helped to establish two scholarship programmes for doctoral students at the University of Oxford (the Oxford-E P Abraham Research Fund Graduate Scholarship and the Oxford-EPA Cephalosporin Graduate Scholarship).

Abraham Wood is a bluebell wood at Boars Hill donated to the Oxford Preservation Trust in memory of Sir Edward and Lady Abraham.[33]

Sir Edward Penley Abraham was a British biochemist known for his instrumental contributions to the development of antibiotics, particularly through his work on the purification of penicillin and the discovery and characterization of cephalosporins. Born Edward Penley Abraham on 10 June 1913 in Southampton, England, he studied at Queen's College, Oxford, where he later held academic positions, including professorship in chemical pathology. During World War II, Abraham collaborated with Howard Florey and others at Oxford on the isolation and purification of penicillin, making key advances that enabled its large-scale production and clinical use. Following this, he and his colleague Guy Newton identified cephalosporin C from a fungus, leading to the development of the cephalosporin class of antibiotics, which became widely used for treating bacterial infections resistant to penicillin. Abraham's research earned him numerous honors, including election as a Fellow of the Royal Society, appointment as Commander of the Order of the British Empire (CBE), and knighthood. He remained active in biochemical research until his later years, leaving a lasting legacy in the field of antimicrobial agents. He died on 9 May 1999.

Personal Life

Birth and Background

Sir Edward Penley Abraham was born on 10 June 1913 at 47 South View Road, Southampton, England, to Albert Penley Abraham, a customs and excise officer, and Maria Agnes Abraham (née Hearne), who was born in Ireland. He had one younger sister, Mary Abraham, born in 1917. His paternal family had deep roots in the Southampton area.

Marriage and Family

Abraham married Asbjørg Harung, from Norway, on 1 November 1939 in Bergen. They met in Oxford in 1938, and due to the German invasion of Norway in 1940, Asbjørg was trapped there until she escaped to Sweden and reunited with him in the UK in 1942. Their only child, Michael Erling Penley Abraham, was born in Oxford in July 1943; he was severely disabled, a matter Abraham rarely discussed. The couple made regular extended visits to Norway, staying at Asbjørg’s family chalet at Gullsteinhovda near Geilo, where they enjoyed skiing and walking. In retirement, they lived quietly at Badgers Wood, Boars Hill, Oxford, and were enthusiastic gardeners. Abraham died on 9 May 1999 at St Luke’s Hospital, Headington, Oxford, following a stroke. He was survived by his wife Asbjørg, who died on 20 May 2001.

Career

Early career and penicillin research

After completing his DPhil at Oxford in 1938 under Sir Robert Robinson, where he became the first to crystallize lysozyme, Abraham spent a year in Stockholm on a Rockefeller Foundation fellowship. He returned to Oxford and joined the team at the Sir William Dunn School of Pathology led by Howard Florey. During World War II, he collaborated with Florey and Ernst Chain on the isolation and purification of penicillin. Abraham introduced alumina chromatography for purification, discovered penicillinase (the enzyme responsible for bacterial resistance to penicillin) in 1940, and co-proposed the β-lactam fused-ring structure for penicillin in 1943, which was later confirmed by X-ray crystallography.

Cephalosporin discovery and development

In 1948, Abraham began investigating the fungus Cephalosporium acremonium (provided by Giuseppe Brotzu). Working closely with Guy Newton, he isolated and purified cephalosporin C in the early 1950s. This compound was resistant to penicillinase and active against penicillin-resistant bacteria. Abraham determined its novel β-lactam-dihydrothiazine structure (conceived in 1958 and published in 1961), and demonstrated that its nucleus, 7-aminocephalosporanic acid (7-ACA), could be modified to produce more potent semi-synthetic derivatives. These findings formed the basis for the cephalosporin class of antibiotics, leading to the first commercial cephalosporin (cephalothin) and subsequent generations.

Academic positions and later research

Abraham was appointed a Nuffield Research Fellow at Lincoln College, Oxford, in 1948 (one of the first "penicillin" fellows), later becoming a Professorial Fellow. He served as Professor of Chemical Pathology at the University of Oxford from 1964 until his retirement in 1980, remaining an Honorary Fellow of Lincoln College. His later work included studies on β-lactamases, the biosynthesis of penicillins and cephalosporins (identifying key intermediates like ACV), and other peptide antibiotics. Abraham assigned patent rights for cephalosporin-related discoveries to the National Research Development Corporation and used much of the resulting income to establish charitable funds supporting research and education. He remained active in biochemical research into his later years.
