Cyrus Caswell Marshall (April 17, 1902 – December 20, 1974)[1] was an American racing driver. Marshall was seriously injured and his riding mechanic, brother Paul Marshall, was killed in the 1930 Indy 500.[1] He returned to the race in 1947.[2] The 17 years between starts was a record he shared with Roland Free, who also competed in only the 1930 and 1947 races, until it was broken by Jacques Villeneuve, who competed in the 2014 race after having last competed in the 1995 race. Marshall also failed to qualify for the 1950 race.[3]
