This folder contains inquiries relating to Edison's well-known idiosyncrasies in nutrition and sleep habits. Among the items from 1919 is a letter from author and publisher William Feather expressing his belief that "every man needs at least seven or eight hours of sleep every night," along with Edison's response that there is "no actual reason why we should sleep, from a scientific standpoint." Also included is a suggestion by Edison on how to stop the progress of tuberculosis.
Four of the seven documents have been selected. The unselected letters were marked for no answer or did not receive a personal reply from Edison.
