Pieter Juriaan van der Heyde Schreuder attended the high school at Franschhoek, Western Cape, and passed the matriculation examination of the University of the Cape of Good Hope in 1906. He continued his studies at Victoria College, Stellenbosch (forerunner of the University of Stellenbosch) and in 1911 was awarded the Bachelor of Arts (BA) degree in literature and science. He then proceeded to the United States to study further at Cornell University at Ithaca, New York State, which awarded him the degree Doctor of Philosophy (PhD) in 1915. His thesis was entitled The Cape horse, its origin, breeding and development in the Union of South Africa.
Upon his return to South Africa Schreuder appears to have been employed in the Department of Agriculture, for during 1916-1917 he compiled notes on the production and export of beef. During the late nineteen-twenties he worked in South West Africa (now Namibia). With D.H. Thompson he wrote an article on 'Karakoel-skaapboerdery' (Karakul sheep farming) in the South West African Farmer (1928). The article was reprinted as a pamphlet by the Department of Agriculture of the territory (Windhoek, 1928, 14p). At this time Schreuder was a member of the South West Africa Scientific Society and served on its council for 1928/9. Back in South Africa twenty years later he and F.B. Wright wrote The horse on the farm (Department of Agriculture, Bulletin No. 293, 1948).
Schreuder married Helena Elizabeth Jacomina Lewis, but they were divorced in 1938. He was survived by his second wife, Olive Claudine Bosscher, but had no surviving children.
