Sylvester Howard Roper (November 24, 1823 – June 1, 1896)[1][2] was an American inventor and a pioneering builder of early automobiles and motorcycles from Boston, Massachusetts. In 1863 he built a steam carriage, one of the earliest automobiles.[3][4][5][6][7] The Roper steam velocipede of 1867–1869 may have been the first motorcycle,[8][9][10][11][12] for which he was inducted into the Motorcycle Hall of Fame in 2002.[13] He is also the inventor of the shotgun choke[14] and a revolver repeating shotgun.[15][16]
