July 1878

First Time Photography Used for Sound Recording

This recording was made in July of 1878 by using photography to record speech vibrations for the first time in history. Eli Whitney Blake, Jr., a great-nephew of cotton gin inventor Eli Whitney, was Hazard Professor of Physics at Brown University, where he conducted a number of telephone exhibitions and experiments. The speaker says "Brown University" and then "How do you do?"
