Michael Ambrosi jun.

Michael Ambrosi jun. (1880–1940) attended the Agricultural School in Mediaș (1894–1897), the dairy school at Sárvár (1897–1898) and the viticultural academy at Budafok, where he graduated in 1903. In 1902 he took the initiative to buy the property at Aiud, named «Ambrosi, Fischer & Co.» in 1905 and managed by him from 1912; in 1906 he published «Der praktische Weinbauer», which went through three editions and a Romanian version at Craiova in 1913. From 1907 he was partner and director of Prince Știrbey's nurseries at Buftea, with 40 ha of rootstock vines, 12 ha of grafted-vine school and 8–10 million vines a year. In 1919 he took over the Gräfenberg vineyards, in 1924 he moved to Mediaș, and in the 1920s he made the clonal selections from which the name Fetească Regală probably derives. He was mayor of Mediaș from 1933.
