Masten Gregory sits in the cockpit of the 1965 BRP Indycar as team manager Tony Robinson looks on.
What brothers? Most motor racing aficionados know something about Masten Gregory. An American, he won Le Mans in 1965 and drove in Formula One. Few, however, remember that he had a brother who also raced. His name was Riddelle. We called him “Rocket.” I met Masten one time, but Rocket and I were good friends.
Somewhat older than his brother, Rocket was born in 1927; Masten in 1932. They came from Kansas City, Missouri, where their father owned an insurance company. The father—Riddelle Sr.—died in 1935. Their mother sold the business, creating a considerable estate. She set aside a significant amount of money for the boys and their sister, Nancy, to receive when they became 21 years old or got married. Masten married Luella Simpson when he was 18.
