Lucien Bull
Lucien Bull died in his Paris flat at the age of 95 on the 25 August 1972.
Bull died in Paris in 1972 as a bachelor, leaving behind no children. He outlived his brother, British cartoonist René Bull, by almost 30 years. Bull's work spanned fields beyond high speed photography, with his bibliography of published papers ranging from military applications of sound in the form of sound ranging and medical papers to recording of video. Much of this was continued research from his work with Étienne-Jules Marey. Bull's work as an assistant with Marey, particularly in regards to developing Marey's camera gun into the higher speed spark-drum camera, was instrumental in the development of the technique of chronophotography, and was key to his appointment as head of the Marey Institute. Chronophotography itself acted as a stepping stone to the development of cinematography and silent film. The lasting effects of the technique are observable to this day, as it provided a foundation for modern cinema. Some of Bull's work has been preserved to this day. A copy of his stereoscopic spark drum camera is held in the National Science and Media Museum of Bradford, England. His research on the heart was later used in the development of the electro-cardiograph. Bull was memorialized in an article for the Irish Engineer's Journal, written by Kenneth Mitchell and published on the 17th of April 2018 .This article gave an overview of Bull's life and accomplishments.
