Lucy Diecks, an art educator in Louisville, studied at the Corcoran Art School in Washington, D.C., and Syracuse University in New York. She was in the first class at the Louisville Art Center. She exhibited from 1929 to 1964. As with several Louisville painters of her generation, she was involved in the art scene in Provincetown, Massachusetts, and also painted in Colorado and New Mexico. According to her niece, Barbara Brooks, Diecks "put down her brushes in the 1960s and never painted again." She didn't know why. Diecks was represented in the ground-breaking exhibition Kentucky Women Artists: 1850-2000 in 2001-2002.
