Early years

He was the son of Sir Hiram Stevens Maxim, inventor of the Maxim Machine gun. He had a sister, Percy Maxim, who married George Albert Cutter. ^[1] Hiram was a mechanical engineering graduate of the Massachusetts Institute of Technology.
Maxim tinkered with internal combustion engines before contacting the Pope Manufacturing Company about the possibility of manufacturing a gasoline-powered automobile. Albert Augustus Pope hired Maxim to run his Motor Vehicle Division. In 1899, with Maxim at the controls, the Pope Columbia, a gasoline-powered automobile, won the first closed-circuit automobile race in the US at Branford, Connecticut. Columbia later began manufacturing an electric automobile.

Marriage

He married Josephine Hamilton, the daughter of the former Maryland Governor William T. Hamilton around 1905, and had a son, Hiram Percy Maxim, Jr.; and a daughter, Percy Maxim who married John Glessner Lee.
Maxim is also noted as the inventor of the "Maxim Silencer" or Suppressor for firearms (patented in 1909) as well as of a silencer (or muffler) for gasoline engines.
He created the ARRL in 1914 because he saw a need to build up an organized group of "Relay" stations to pass messages via amateur radio. This allowed messages to pass farther than any particular station of the time could reach.
H.P. Maxim wrote an amusing account of his youth in the book "A Genius in the Family: Sir Hiram Stevens Maxim Through a Small Son's Eyes." H.P. Maxim recounted his days as an automobile pioneer in his book "Horseless Carriage Days."

Death

Hiram Percy Maxim was returning to his home in Hartford, Connecticut, in February, 1936, from a trip to California to visit the Lick Observatory. He fell ill and was taken from the train to a hospital in La Junta, Colorado, where he died the following day, February 17, 1936. Hiram P. Maxim was buried in the Rose Hill Cemetery in Hagerstown, Maryland, some days later. Hiram Maxim was buried in the Hamilton family plot belonging to his wife's family. ^[2]
