The French oenologist Adhémar de Chaunac (*1896) emigrated to Canada in 1907, but returned temporarily to France to serve in the French army between 1915 and 1919 during the First World War. After training as a chemist, he worked in Canada for the dairy and yeast industry. From 1933 to 1961, he was the responsible chief oenologist at Brights Wines in Niagara Falls, Ontario. He also served as a consultant in Canada and the eastern United States, introducing a total of 35 hybrid vines, including Baco Noir, later named De Chaunac, Léon Millot, Maréchal Foch and Vidal Blanc. The resulting wines were the first in North America to be made without the foxtone that is usually present in other varieties. He also founded the production of ice wines. Chaunac is considered a pioneer in viticulture with a great influence on North America's wine industry.
