Douglas Leigh (1907-1999) was an advertising designer and executive from New York, N.Y.
He was responsible for festooning Broadway with miles of spectacular electrical and animated signs, such as a steaming coffeepot, a winking penguin on a cake of ice for Kool cigarettes, and the giant Camel sign that puffed smoke rings from a Times Square sign from 1941 to 1967. These effects led to creating animated billboards, an innovation called the Leigh-EPOK animated, billboards matrix display, or EPOK. Leigh was also a pioneer in the illumination of city skylines and buildings.
