George Robert Marshman (September 24, 1936 – December 3, 1964), was an American racecar driver. Born the son of auto race promoters George and Evelyn Marshman in Pottstown, Pennsylvania, Marshman died in San Antonio, Texas of injuries sustained in a tire test in Phoenix, Arizona. About a year after her husband's death, Marshman's widow, Janet F. Marshman, sued Ford Motor Company for $5 million, claiming that the crash resulted from negligence by the car owner, purported to be Ford, which also failed to comply with a warranty that the car was safe according to the suit.
