John Graham Kerr was born on 18 September 1869, at Arkley, Herts, the son of James Kerr, M.A., a former Principal of Hoogly and Hindu College, Calcutta, and of Sybella Graham, of Hollows, Dumfriesshire. He was third in a family of four with three sisters. His father was a well-known educationalist and the author of various works dealing with a number of topics including Indian educational problems, English orthography and aspects of human nature, and Thomas Carlyle. Graham Kerr, as he was known throughout the greater part of his life, lost his mother in early childhood and grew up under the influence of his father who although his tastes were mainly literary had a broad interest in general science, especially in natural history and evolution, in which he was widely read. His father superintended the early stages of his education, including latin and mathematics, and encouraged the reading of such books as Darwin’s
The voyage of the Beagle
, Waterton’s
Wanderings
, Wallace’s
Amazon and Malay Archipelago
, etc. In addition, his library contained a large selection of classical works, especially poetry and history, and Graham Kerr was brought up in a general atmosphere of literary culture. His schooling began at the parish school of Dalkeith, Midlothian, under William Young, a good example of the old-fashioned type of parish schoolmaster who did not hesitate to give special time and attention to any boy who in his opinion possessed the natural capacity to benefit by his teaching. After a short time at the Collegiate School, Edinburgh, he passed on to the Royal High School, where he was specially influenced by Munn, the mathematics master under whose tuition he became Dux of the Fifth Form. He subsequently enrolled in the University of Edinburgh and first concentrated on higher mathematics and natural philosophy. He then studied geology, botany and zoology and finally decided to follow out the curriculum in medicine. This was interrupted when on a wintry afternoon in February 1889, this young medical student of nineteen, returning home from his classes picked up a copy of
Nature
at the book-stall in Waverley Station, and read an announcement which in his own words ‘determined the whole future of my life’.
