Hugh Paterson Donald CBE FRSE (1908–1989)[1] was a New Zealand-born, British biologist, noteworthy as an important contributor to Peter Medawar's research on skin grafts.
[3] At the beginning of his career he was interested in finding new varieties of wheat, but the plant geneticist Otto Frankel advised him that there were more job opportunities in agricultural research on animals.
[1] In the 1930s he worked with cytologists, geneticists, pharmacologists and his colleagues included Auerbach, Muller, Greenwood, Buchanan-Smith and Koller who all contributed to the new science of agricultural and pure genetics.
[1]ABRO grew under his directorship to run six farms in the UK developing improved breeds such as Friesian, Ayrshire, Jersey cattle, and Blackface sheep.
His studies of identical and fraternal twin cattle successfully improved fertility, body weight and milk flow.
