John William Heslop Harrison, (1881–1967) was a professor of Botany at Kings College, Newcastle-Upon-Tyne, specialising in the genetics of moths. He is now best remembered for a widely recognised academic fraud.
Early life and education
He was born in Birtley on 22 January 1881, the son of George Heslop-Harrison, a pattern-maker at Birtley Iron Works. He was educated at Bede College School in Durham then Rutherford School for Boys in Newcastle upon Tyne. His mother was a keen gardener, and other influences such as his uncle, Rev J E Hull, and neighbour, Charles Robson, led him to an early interest in botany and natural history.
He then studied at Durham College of Science, where he obtained a BSc degree in 1903. He did further postgraduate study at the University of Newcastle, gaining an MSc degree in 1916 and a DSc in 1917.
In 1921 he was elected a Fellow of the Royal Society of Edinburgh (FRSE). His proposers were James Hartley Ashworth, Sir Thomas Hudson Beare, Percy Hall Grimshaw, and James Ritchie. He served as the Society's Vice-President 1945–1948. He was elected a Fellow of the Royal Society (FRS) in 1928. In 2008 further proof about the forgeries committed by Heslop-Harrison emerged.
Lamarckian experiments
Heslop Harrison was described as a loner who avoided as much contact as possible with other professionals and conducted most of his experiments at his home in Birtley, Tyne and Wear. According to researcher Michael A. Salmon "Heslop Harrison claimed to have experimental proof that physical changes in the life of an individual moth or sawfly could be passed on to its progeny, according to the theory of Lamarck... For example, Heslop Harrison thought that melanism resulted from the effect of pollution on individual moths which somehow altered their genes. When others attempted to repeat his experiment, however, they always seemed to come up with different results." His experiments were criticised by J. B. S. Haldane.
Family
In 1906 he married Christian Watson Henderson. Their eldest son was George Heslop-Harrison FRSE who also came to fame as an entomologist.
Heslop Harrison's fourth son was Jack Heslop-Harrison who became director of the Royal Botanic Gardens, Kew in 1970. His daughter Helena married the botanist William Andrew Clark.
