His older brother Hiram Maxim invented the Maxim gun, the world’s first truly automatic machine gun. Hudson Maxim was later a somewhat eccentric writer on a number of social, cultural and political issues. His last years were spent developing resort property at Lake Hopatcong, N.J. This collection focuses on his attempts to float his inventions in England during the late 1890s, his anti-pacifist crusade, and his work at Lake Hopatcong.
