Norman George Heatley OBE (10 January 1911 – 5 January 2004) was an English biologist and biochemist. He was a member of the team of Oxford University scientists who developed penicillin. Heatley developed the back-extraction technique for efficiently purifying penicillin in bulk.

Early life

He was born in Woodbridge, Suffolk, and as a boy was an enthusiastic sailor of a small boat on the River Deben, an experience which gave him a lifelong love of sailing. He attended school at Westbourne House in Folkestone, followed by Tonbridge School, then went on to St John's College, Cambridge, where he studied Natural Sciences, graduating in 1933. His doctoral research in Cambridge led to a PhD in 1936, and he then moved to the University of Oxford, where he became a fellow of Lincoln College and joined a team working under Howard Florey that included Ernst Chain.

Production problem

Alexander Fleming had first discovered penicillin by accident in 1928, but at that time believed it had little application. When Florey and his team recognised the potential of the discovery for combating bacterial infection, they faced the problem of how to manufacture penicillin in sufficient quantities to be of use. Heatley, although the junior member of the team, possessed a natural gift for ingenuity and invention. It was he who suggested transferring the active ingredient of penicillin back into water by changing its acidity, thus purifying the penicillin.

In order to conduct tests on human patients, even more of the drug had to be produced, and again it was Heatley who realised that the most effective vessel for this purpose was something like the porcelain bedpans in use at the Radcliffe Infirmary. These were in short supply because the ongoing World War II, so Heatley designed a modified version which was manufactured in the Potteries. With the help of these, the Oxford laboratory became the first penicillin factory, and subsequent tests on humans proved the efficacy of the new treatment. Even so, it was very difficult to produce enough for sustained treatment.

Trials on humans

In December 1940, a 43-year-old police constable, Albert Alexander, was accidentally scratched by a rose thorn on his mouth and was succumbing to septicaemia. Alexander was admitted to the Radcliffe Infirmary, where various conventional treatments all failed, and his case was brought to Florey and Heatley's attention. Having previously tried penicillin only on mice, Heatley was concerned about the side effects large doses of penicillin might have. On 12 February 1941, Alexander was given an intravenous infusion of 160 mg (200 units) of penicillin. Within 24 hours, Alexander's temperature had dropped, his appetite had returned and the infection had begun to subside. However, owing to the instability of penicillin and the wartime restrictions placed on Florey's laboratory, only a small quantity was available, and Florey and colleagues had run out by the fifth day and Alexander died a month later.

Illinois and New Jersey

Eventually, Heatley and Florey travelled to the United States in 1941 because they wanted to produce about one kilogram of pure penicillin, and persuaded a laboratory in Peoria, Illinois, to develop larger-scale manufacturing of it. In Peoria, Heatley was assigned to work with Dr. A.J. Moyer. Moyer suggested adding corn-steep liquor, a by-product of starch extraction, to the growth medium. With this and other subtle changes, such as using lactose in place of glucose, they were able to push up yields of penicillin to 20 units per millilitre. But their cooperation had become one-sided. Heatley noted, "Moyer had begun not telling me what he was doing."

Florey returned to Oxford that September, but Heatley stayed on in Peoria until December; then for the next six months, he worked at Merck & Co. in Rahway, New Jersey. In July 1942, he returned to Oxford and was soon to learn why Moyer had become so secretive. When he published their research results, he omitted Heatley's name from the paper, despite an original contract which stipulated that any publications should be jointly authored. Fifty years on, Heatley confessed that he was amused, rather than upset, by Moyer's duplicity. Later he was to learn that financial greed had led Moyer to claim all the credit for himself. To have acknowledged Heatley's part of the work would have made it difficult to apply for patents, as he did, with himself as sole inventor.

Achievement

As Sir Henry Harris put it succinctly in 1998:

"Without Fleming, no Chain or Florey; without Florey, no Heatley; without Heatley, no penicillin."

Yet while Fleming, Florey and Chain jointly received the Nobel prize for their work in 1945, Heatley's contribution was not fully recognized for another 45 years. It was only in 1990 that he was awarded the unusual distinction of an Honorary Doctorate of Medicine from Oxford University, the first given to a non-medic in Oxford's 800-year history. In 1978, he received an OBE.

Final years

Heatley died on 5 January 2004 at his home, 12 Oxford Road, Old Marston, near Oxford, which now bears a commemorative blue plaque in his honour. He was cremated in a cardboard coffin after a funeral service at St Nicholas's Church, Marston, on 15 January 2004. Heatley was survived by his wife, Mercy, and four children, Rose, Chris, Jonathan and Tamsin.

Legacy

After Heatley died in 2004, Oxford University established a Norman Heatley Postdoctoral Award for researchers showing excellent ingenuity and problem-solving skills. Heatley's papers are archived within the Wellcome Collection in London.
