Title: Indianapolis 500 by year
Content:  From 1952 to the mid-1960s. Considered by many as the "golden era" of the Indy 500, it is highlighted by the participation of the front-engined Roadsters. The first "roadster" is regarded to have been built and entered by Frank Kurtis in 1952. During this time (1950–1960), the Indy 500 awarded points towards the World Championship of Drivers. However, very few European entries even made an attempt to race at Indy. Noteworthy moments include the emotional victory by Sam Hanks in 1957, as well as the tragic death of two-time winner Bill Vukovich. The famous 1960 duel between Rodger Ward and Jim Rathmann set the race record for the most lead changes in Indy 500 history, a record that remarkably would not be broken until 2012. Indy legend A. J. Foyt debuted in 1958, and won his first 500 in 1961. In the fall of 1961, the last of the remaining original brick pavement was paved over in asphalt, and in 1962 Parnelli Jones famously broke the 150 mph barrier.
