Bob Sweikert was born in Los Angeles, California, in 1926, and started racing midgets in the late 1940s. He attempted big cars in 1950, being DNQ at Indy 500 in 1950 and 1951. Finally Sweikert ran his first Indy 500 race in 1952. In 1955 Indianapolis 500 Sweikert was entered by John Zink, owner of John Zink Company, which his father had founded in 1929. By then, the company had specialized in manufacturing burners, flares, and incinerators for the petroleum and related industries. Zink was one of the premier Indy car owner and sponsor in the 1950s-60s. He signed Sweikert for the 1955 AAA National Championship, which started from the Indy 500 race. Sweikert was qualified 14th, and was among the leaders after the horrific crash on lap 57 which brought the life of 1953 and 1954 Indy winner Bill Vukovich. Sweikert battled with Art Cross and Don Freeland, and about 100 miles to go he runs third. Cross blows engine on lap 169, and Freeland’s transmission broke 10 laps later. That clears the way for Sweikert’s rose and white roadster, which coast to victory more than two laps ahead of Tony Bettenhausen’s Kurtis. Later that season Sweikert recorded one more win and five more podiums in remaining 10 races of the National Championship. Sweikert became the only driver in history to win the original American motor sports Triple Crown in 1955, by sweeping the Indianapolis 500, the AAA big car National Championship, and the Midwest sprint car championship. Sweikert died in a sprint car crash occurred on June 17, 1956, at Salem Speedway.
