Before his death in 1903, Muybridge would emigrate to America, change his name three times, come close to death and suffer brain damage in a carriage accident. Perhaps most sensationally, he would also be acquitted for the murder of Major Harry Larkyns, his wife’s lover, and the true father of his presumed son Floredo Helios Muybridge.
In fact, Muybridge enjoyed a professional life which may even have surpassed his sensational personal biography. He gained fame through adventurous and progressive landscape photography before working as a war and official government photographer; something which took him from the Lava beds of California during the Modoc War to Alaska and Central America.
Furthermore, Muybridge was instrumental in the development of instantaneous photography. To accomplish his famous motion sequence photography, Muybridge even designed his own high speed electronic shutter and electro-timer, to be used alongside a battery of up to twenty-four cameras!
While Muybridge’s motion sequences helped revolutionise still photography, the resultant photographs also punctuated the history of the motion picture. Muybridge actually came tantalisingly close to producing cinema himself with his projection device the ‘Zo√∂praxiscope’.

April 9, 1939: Marian Anderson’s Easter Sunday Lincoln Memorial concert


Marian Anderson, contralto, was denied the right to perform at Constitution Hall by the DAR because of her color. Instead, and at the urging of Eleanor Roosevelt, Harold Ickes permitted her to perform at the Lincoln Memorial on April 9, 1939.
