John Emery Harriman, Jr. (June 3, 1869 — May 18, 1916) was an American civil engineer and inventor.
Harriman was born in 1869 in Somerville, Massachusetts, to John Emery Harriman, Sr., a Civil War veteran of the 6th Massachusetts Regiment, and Sarah Jane Wheeler Harriman.[2] His paternal family went back eight generations to 1622, when the Harrimans left Rowley, Yorkshire, England.[3]
He created the Harriman Aeromobile Company[4] and designed a flying machine in 1902. He also designed an aerocar in 1906, which was patented in 1910, but was never manufactured.[5] [6] He also invented a rotary steam engine.[1]
He married Julia C. Horther, ex-wife of artist Hiram Peabody Flagg,[7] on April 22, 1897. He died at his home in Brookline, Massachusetts, aged 46, after a brief illness.[1]
