Lieutenant Colonel Joseph Janvier Woodward (1833-1884), commonly known as J. J. Woodward, served in the U.S. Civil War as Army Assistant Surgeon, microscopist and an instrumental pioneer in photomicroscopy. Woodward performed and wrote reports on the autopsies of both Abraham Lincoln and John Wilkes Booth. He also attended to president Garfield after he was shot. Woodward was the first scientist to establish photomicrography as a tool for both scientific and medical investigations. He died in 1884 at the age of 51.
