DescriptionRoland Sumner in an informal portrait from shoulder height.
Roland Martin Winchester Sumner was born in London but moved to New Zealand as a young child.
He joined the Department of Agriculture in 1966 as a Wool Advisory Officer, gaining his B.Agr.Sc, M.Agr.Sc, and diplomas in wool. In 1978 he was awarded his Ph.D. from the University of New England, Armidale, for the thesis 'Nutritional factors affecting production in Border Leicester and Super-Fine Merino sheep with emphasis on protein nutrition'.
Sumner's whole career centered on wool research, predominantly at Whatawhata Hill Country Research Station, where he specialised in wool biology, with his most significant contribution being on loose wool bulk.
A long career included a significant involvement in the wider profession, including President and other roles in the NZ Society of Animal Production (1996-2006), positions in the Black and Coloured Sheep Breeders Association (1977-2002), and Massey Wool Association (1978-2001). In 2010 he was awarded Honorary Life Membership of the New Zealand Society of Animal Production.
After leaving AgResearch, Sumner continued his involvement in wool research.Size of originalUnknownCreatorUnknownColourColourLanguageN/A
