In the late 1930s, an early pioneer of the American viticulture, Paul Masson, brought with him several Burgundian grapes for his winery in California. One of those grapes he believed to be the Gamay variety from the Beaujolais region in France, which in the 1940s University of California at Davis (UCD) researchers christened "Gamay Beaujolais". In the late 1960s, UCD scientists decided that Gamay Beaujolais was a clonal selection of Pinot noir, and that California's version of the true Gamay
History of manifolds and varieties spaces with a differentiable or topological structure, while "variety" refers to spaces with an algebraic structure, as in algebraic varieties. In Romance languages, manifold is translated as "variety" – such spaces with a differentiable structure are literally translated as "analytic varieties", while spaces with an algebraic structure are called "algebraic varieties". Thus for example, the french word "" means topological manifold. In the same vein, the Japanese word "" (tayōtai) also encompasses both manifold and variety. ("" (tayō) means various.) Ancestral to the modern concept of a manifold were several important results of 18th and 19th century mathematics. The oldest
