Dorothy Quick (1896-1962) was an American writer and poet who became friends with Mark Twain as a girl, who encouraged her write. Mark Twain formed a club in 1906 for girls whom he viewed as surrogate granddaughters called the Angel Fish and Aquarium Club. The dozen or so members ranged in age from 10 to 16. He exchanged letters with his "Angel Fish" girls and invited them to concerts and the theater and to play games. Twain wrote in 1908 that the club was his "life's chief delight." In 1907, he met Dorothy Quick (aged 11) on a transatlantic crossing, beginning "a friendship that was to last until the very day of his death."
