Olmo Harold

The American botanist, plant physiologist, enologist and vine breeder Dr. Harold Paul Olmo (1909-2006) studied horticulture and genetics at the University of California at Berkeley. Towards the end of the American Prohibition, he was appointed professor of viticulture at the reactivated Department of Viticulture and Enology at the University of California at Davis in 1931 and entrusted by the head of the institute, Albert Julius Winkler (1894-1989), with the task of breeding new grape varieties. He subsequently became the leading grapevine geneticist of his era. By the time of his retirement in 1979, he had created several thousand new varieties, about 30 of which were included in the National Variety Lists.
