Charles T. Jeffery's (Thomas' son) experimental prototypes of 1901 (Models A & B) used at least two radical innovations - steering wheels and front-mounted engines. By the time Charles was ready for production in 1902, his father had talked him out of these wild dreams and convinced him to stick with tillers and engines under the seat. In 1915, Charles T. Jeffery, changed the automotive branding from Rambler to Jeffery to honor the founder, his father, Thomas B. Jeffery.
