Grimm was one of the “barnstorming”
drivers of the early days of midget auto racing who appeared
all over the country and raced where the money was. In 1941 he
won the Toledo, Ohio Fort Miami Speedway track Championship.
In 1945 he captured the Toledo title again and
then won the famous “Turkey Night Grand Prix” at Gilmore
Stadium in
1946. He repeated as the winner
of the “Turkey Night” classic in 1949 and won the Pacific
Coast Midget title as well.
His third-place finish at New York’s Roosevelt Raceway
open competition show in 1939 is still talked about as he
drove the last 55 miles of the 150-miler with a flat tire.
That race was watched by a crowd of 61,256.
He passed his drivers test for the Indianapolis 500
Mile Race in 1952 but never earned a spot in the starting
field.
