Lee de Forest
In 1918 he had his first major success with his play "Abraham Lincoln". He followed it with others in a similar vein, including "Mary Stuart" and "Oliver Cromwell". In 1924, his Lincoln play was adapted for a two-reel short film made by Lee de Forest and J. Searle Dawley featuring Frank McGlynn Sr. as Lincoln, and made in de Forest's Phonofilm sound-on-film process.
