Below is a collection of articles about the great American driver Joe Dawson who won the second Indianapolis 500 Mile Race in 1912. Also check out this article on Joe from Vanderbilt Races.
Earl Kiser was one of America's early professional auto racing drivers and a chief rival to his much more well-known contemporary, Barney Oldfield. Kiser succeeded Oldfield on Alexander Winton's Bullet II race car when Barney and Winton had a falling out. Kiser was also a colleague of Indianapolis Motor Speedway founder Carl Fisher.
I just uploaded a photo of driver Joe Jagersberger sporting the safety gear he intended to don for the first Indianapolis 500. The image, as you can see, is pretty bizarre and could have easily worked to depict a Martian in "B" sci-flick from the 1950's. In that regard, I guess old Joe was ahead of his time.
