Early life and education
Born in Marshalltown, Iowa, on April 30, 1865, Henderson was a ninth-generation American. He was of Scottish descent and was the son of a district court judge. By age 22, he was working as the editor of a small Washington newspaper. In 1892, he moved with his parents to Boulder, Colorado, where he worked in a law office. Two years later, he became a lawyer. By 1902 he had become a county judge and a law instructor at the University of Colorado. He had always been avidly interested in nature, so when he discovered that the university's natural history collection was small and poorly maintained, with no official curator, he volunteered to take care of it.Career
He was appointed the honorary curator of the Museum (without pay) in 1902, when "the whole collection would have gone into a good sized wagon, and was of no value." The collection at that time consisted of “a few fossils and mollusk shells, a small collection of rocks and minerals, and several mounted bird and mammals.” “During his early years as judge and curator,” according to one source, “Henderson found time to earn a bachelor's degree from the university. Instead of attending graduation, he went exploring for fossils.” Working closely with ProfessorsHonors and awards
Henderson was elected a member of the Malacological Society of London in 1913.Personal life
Henderson was married to his first wife, Nellie, for 30 years. She died in 1924. He married his second wife, Bess, a zoologist and teacher, in 1929.Selected publications

In the abstract to this book-length paper, Henderson writes that “in the Rocky Mountain States and the adjacent territory and extending far northward into British America, the non-marine formations are so extensive, of such thickness, and so associated with thick coal beds and other deposits of economic importance, that they are of great consequence to the geologist” but “present more complex and difficult problems than marine deposits generally do, which results in much disagreement as to the age and correlation of some of the formations.” The book seeks to provide a “comprehensive, systematic review and index” of the literature on this subject and “to clear up many problems in synonymy, geologic and geographic distribution of species, and so on.” *Henderson, J. 1935.
