The pomologist Thomas Andrew Knight, president of the Horticultural Society of London (1811-1838), first called attention to hybrid vigor in apples and pears. He sent many new varieties to America early in the nineteenth century, including the "Old Quining," a variety of cider apple. In his treatise on apple and pear cultivars, the plates were hand-colored.
