Raffaele "Ralph" DePalma (occasionally spelt De Palma, December 19, 1882 – March 31, 1956) was an American racing driver who won the 1915 Indianapolis 500. DePalma won the 1908, 1909, 1910, and 1911 American AAA national dirt track championships and is credited with winning 25 American Championship car races. When he arrived in the US he was told that, because his father had become a naturalized US citizen, he was automatically a US citizen himself. It was not until March 1920 that it was revealed to him that his father had not completed the paperwork required. He applied for US citizenship and was granted it in August 1920. As a young man, he tried bicycle racing with mixed success, but at the age of twenty-two, he began racing motorcycles before switching to the automobile dirt track racing circuit in 1909, the year that the American Automobile Association established the national driving championship.
DePalma was immediately successful in car racing. In 1911, DePalma won the first Milwaukee Mile Championship Car race. However, he is still remembered for the dramatic manner in which he lost the 1912 Indianapolis 500. After taking over the race lead on lap 3 and then leading the race for the next 196 laps, his car, a 1910 Mercedes 90 hp with overhead valves, cracked a piston. With only two laps remaining, he and his mechanic had to push the car across the finish line to take eleventh place. but was almost killed in an accident on October 5 at the Grand Prize held in a road course in Milwaukee. After being impaled by a corn stalk, he was hospitalized for 11 weeks;
DePalma was an intense competitor but one of the most popular racers with his fellow drivers and the fans because of his good sportsmanship, a quality he displayed on and off the track. In June 1917 he lost to Barney Oldfield in a series of 10 to 25 mile match races at the Milwaukee Mile. On February 12, 1919, at Daytona Beach, Florida, he drove a Packard to a world speed record of over a measured mile (1.6 km). and he led for many laps
DePalma later competed in stock cars until he retired from racing in 1936. He was interred in the Holy Cross Cemetery in Culver City, California.
