The French oenologist Adhémar de Chaunac (*1896) emigrated to Canada in 1907, but returned to France temporarily to serve in the French army during the First World War between 1915 and 1919. After training as a chemist, he worked in Canada for the milk and yeast industry. From 1933 to 1961, he was the head oenologist at Brights Wines in Niagara Falls , Ontario. He also worked as a consultant in Canada and the eastern USA, introducing a total of 35 hybrid vines during this time, including Baco Noir, De Chaunac, which was later named after him, Léon Millot, Maréchal Foch and Vidal Blanc. The wines made from these grapes were the first in North America to be produced without the foxy that was usually present in other varieties. He also established the production of ice wines. Chaunac is considered a viticultural pioneer with great influence on North America's wine industry.
For me, Lexicon from wein.plus is the most comprehensive and best source of information about wine currently available.
