He was a gifted student, and studied law at both Harvard and Oxford before his athletic career.
After his Olympic days, he served for his country in World War II.
He was born in Denver, Colorado.
He joined Gillis Grafstrom as the only people to win gold medals in the summer and winter Olympics, but since Grafstrom earned both in the same event, he kept his own record.
