Life

In 1890 he went to Washington, DC, where he worked as a stenographer . In the following year he began to experiment with cinema and developed his Phantascope , which he improved from 1895 together with Thomas Armat and presented at the Cotton States and International Exposition in Atlanta. Armat sold the patent rights to Thomas Edison , who marketed it under the name Vitascope .

Jenkins then turned to television and published an article Motion Pictures by Wireless in 1913 . In 1923 he was able to transmit moving shadow images and two years later transmit sound and image synchronously. In June 1925 he received a patent for his wireless image transmission.

From July 1928, the Jenkins Television Corporation regularly broadcast 48-line television pictures of films at 15 frames per second via its test station W3XK near Washington. In March 1932 the company was liquidated.
