David Lack

Résumé
David Lambert Lack FRS (16 July 1910 – 12 March 1973) was a British evolutionary biologist who made contributions to ornithology, ecology, and ethology. His 1947 book, Darwin's Finches, on the finches of the Galapagos Islands was a landmark work as were his other popular science books on Life of the Robin and Swifts in a Tower. He developed what is now known as Lack's Principle which explained the evolution of avian clutch sizes in terms of individual selection as opposed to the competing contemporary idea that they had evolved for the benefit of species (also known as group selection). His pioneering life-history studies of the living bird helped in changing the nature of ornithology from what was then a collection-oriented field. He was a longtime director of the Edward Grey Institute of Field Ornithology at the University of Oxford. Lack was born in London, the oldest of four children of Harry Lambert Lack MD FRCS, who later became President of the British Medical Association. The name 'Lack' is derived from 'Lock'. His father grew up in a farming family from Norfolk and became a leading ear, nose and throat surgeon at the London Hospital. Although his father had some interest in birds as a boy it does not appear that he influenced David's interest. His mother Kathleen was the daughter of Lt. Col. McNeil Rind of the Indian army. Kathleen's father was Scottish and on her mother's side was part Irish, Greek and Georgian. Kathleen had been an actor and was a supporter of women's suffrage. At home they organized meetings of the poetry society. David was schooled at home until seven and then went to the Open Air School in Regent's Park before going to The Hall, Hampstead followed by Foster's School, Stubbington and Gresham's School, Holt, Norfolk. Lack was taught biology at Gresham's by W.H. Foy and G.H. Lockett. He went to Magdalene College, Cambridge and received a BA second class in 1933 after studying botany, zoology and geology for part I of the Tripos and zoology for part II.
