Kerr, Sir John Graham. ( 1869-1957) Zoologist and Professor of Natural History, University of Glasgow, Scotland

John Graham Kerr was born at Rowley Lodge, Arkley, Barnet, England on 18 September 1869 . He was commonly known as Graham Kerr. He was educated at the Royal High School, Edinburgh, Scotland, and at the University of Edinburgh , where he studied Mathematics and Philosophy, before enrolling in the Medical Faculty. He interrupted his medical studies to join an Argentine expedition, led by Captain Juan Page. He returned to England in 1891 and entered Christ's College, Cambridge, gaining First Class Honours in both parts of the Natural Sciences Tripos ( 1894-1896 ).

In 1903, he married Elizabeth Mary Kerr and had two sons and one daughter. His first wife died in 1934, and in 1936 he married Isobel, the widow of Alan E Clapperton, LLD.

In 1896 , he made an expedition to Paraguay to study the South American Lungfish (Lepidosiren), accompanied by J S Budgett. Their collections of specimens, and those of three further expeditions to the Chaco region, have been preserved in the Hunterian Museum at the University of Glasgow, Scotland. On his return from Paraguay in 1896, he was appointed demonstrator in Animal Morphology at Cambridge University, a post he held until 1902.

He was a Fellow of Christ's College, Cambridge from 1898-1904 and was appointed Regius Professor of Zoology at the University of Glasgow in 1902 . During his professorship he concentrated on teaching medical students, using a largely morphological and embryological approach. This approach is reflected in his books: Zoology for Medical Students (1921) and ntroduction to Zoology (1929).

Graham was elected a Fellow of the Royal Society in 1909 and held office in many scientific societies and organisations including president of the Scottish Marine Biological Association ( 1942-1949 ) and as a member of the Advisory Committee on Fishery Research from 1919-1949. He served on the council of the British Association, being President of the Zoology Section at the Oxford meeting in 1926.

In 1939 Graham Kerr was given a knighthood. Other awards included Honorary Degrees of LLD from Edinburgh University (1935) and St. Andrews University (1950); Honorary Fellowship of Christ'College, Cambridge (1935); the Linnean Gold Medal (1955); and Associate Membership of the Royal Academy of Belgium (1946).

Kerr was particularly interested in war camouflage, and he corresponded with the Admiralty at great length. His suggestion for the use of obliterative shading and disruption was adopted, and was used extensively during the 1939-1945 World War. He also claimed to have invented dazzle painting of warships in 1914, although the collection of papers reflects the dispute over his claim.

n 1935, he was elected as the Independent Member of Parliament for the Scottish Universities, serving until the abolition of University seats in 1950. At the time of his election he resigned his post at the University and moved to live at Barley, near Royston, Hertfordshire, England, where he died on 21 April 1957 .
