N. J. Berrill
Norman John ("Jack") Berrill (28 April 1903 – 16 October 1996) was an English marine biologist. He was born in Bristol and received his BSc degree from the University of Bristol and his PhD and DSc from the University of London. In 1928, he joined the faculty of McGill University in Montreal, where, from 1946 to 1965, he was Strathcona Professor of Zoology. On 20 March 1952 he was named a Fellow of the Royal Society. He was also a member of the Royal Society of Canada (1936) and the American Association for the Advancement of Science (1978 ). Berrill wrote numerous books, including both works of popular science which were compared by some reviewers to books by Rachel Carson and Loren Eiseley, as well as textbooks and scientific monographs. Two of his titles, "Man's Emerging Mind" and "Sex and the Nature of Things", won the Canadian Governor General's Award for English-language non-fiction. His 1950 monograph on tunicata is the definitive work on the subject. Berrill received honorary doctorates from the universities of Windsor (1968), British Columbia (1972) and McGill (1973). Berrill was married twice and had three children, raising his first child as a  single parent after his first wife died. He co-wrote two books with his son and his second wife.
