In 1864 he became a professor of anatomy and physiology at the University of Maryland and in 1869 he succeeded Nathan R. Smith as chair of surgery. Johnston was noted for being a patient microscopist, experimenter, and a skilled artist.[2] In 1881 he published his studies on the antennae of Culex mosquitoes. He was involved in the founding of the Maryland Academy of Sciences. In 1873 he was successful in removing the complete upper jaw of a patient. He was a consulting surgeon for Johns Hopkins hospital devised instruments for surgery and bequeathed his instruments to Johns Hopkins University.[3][4]
Johnston wrote mainly on medical topics, including an entry on plastic surgery for Ashhurst's Encyclopedia. His most influential work was on a study of the antennae of mosquitoes and the auditory organ on it[5] which is now known as Johnston's organ.[6] A fossil sauropod genus that he suggested the name Astrodon for on the basis of a tooth was described as Astrodon johnstoni by Joseph Leidy.[7]
