William John Vukovich Sr. (; December 13, 1918 – May 30, 1955) was an American automobile racing driver of Serbian descent. He won the 1953 and 1954 Indianapolis 500, plus two more American Automobile Association National Championship races, and died while leading the 1955 Indianapolis 500. Several drivers of his generation have referred to Vukovich as the greatest ever in American motorsport. Racer Midget car Before he began Indy racing, Vukovich drove midget cars for the Edelbrock dirt track racing team. He raced on the West Coast of the United States in the URA, and won the series' 1945 and 1946 midget car championships. Vukovich won the 1948 Turkey Night Grand Prix at Gilmore Stadium, and six of the last eight races at the stadium track before it was closed for good. He won the 1950 AAA National Midget championship. Vukovich was known for racing midgets powered by Drake engines. The Drake was a Harley V-twin with specially built Drake water cooled heads. His last Drake powered midget was a Kurtis-Kraft that was built by Ed and Zeke Justice, the Justice Brothers, in their shop in Glendale from a Kurtis kit. Previous to this car Vukovich drove a "Frame Rail" midget that was also powered by a Drake engine.

He returned to win the race in consecutive years, 1953 and 1954. He led an astounding 71.7% of laps that he drove in competition at the track, and remains the only driver ever to lead the most laps in the race three consecutive years. Death at Indianapolis Vukovich was killed in a chain-reaction crash while holding a 17-second lead on the 57th lap of the 1955 Indianapolis 500. He was exiting the second turn, trailing three slower cars—driven by Rodger Ward, Al Keller, and Johnny Boyd—when Ward's car hit the backstretch outer wall and flipped, resting in the middle of the track as a result of a broken axle. Keller, swerving into the infield to avoid Ward, lost control and slid back onto the track, striking Boyd's car and pushing it into Vukovich's path. After his car went over the
