Joannes Seyve (1900–1966) was a French biochemist who often used Seibel wine grape hybrids first produced in the 1860s. He created the Chambourcin grape,[1] a French hybrid variety that is grown extensively in the Midwest and Northeast United States.[2] His variety Joannes-Seyve 23.416 was crossed with Gewürztraminer to produce the Traminette grape.[3]
His father Bertille Seyve (1864–1939), and brother Bertille Seyve Jr. (1895–1959)[4] also produced new hybrid Grape varieties (identified as Seyve-Villard) including Seyval blanc and Villard Noir.[5]
