Here’s a photograph from the July 19 1928 edition of the Toronto Daily Star of a woman who beat her husband in a road race in England.
A Google search turned up an interview with W. B. Scott in Motor Sport magazine in 1976. From this, I learned that W. B. Scott’s nickname was “Bummer”, he was from a wealthy background (his family owned Calgary Castle in the Isle of Mull and had over 2000 acres of shooting rights), he was a former Scottish squash champion, and his wife’s name was Jill.
The article describes Mr. Scott’s racing exploits in some detail, but doesn’t explain what happened to his wife. It does include the fascinating detail that the couple’s daughter, Sheila, sat in a race car travelling at over 100 mph at the age of five months; Daddy drove, while Baby sat in Mommy’s lap.
