He and his twin brother Fred attended East High School and came to their father's university to play basketball for coach Vadal Peterson in the Fall of 1943.
Due to the shortage of college-aged men associated with World War II, freshmen were eligible to play varsity basketball (freshmen wouldn't become permanently eligible until 1973). Following the championship season, the Lewis twins joined the Army for World War II. After their stint in the military, both Lewises moved to Stanford University to finish their academic careers. Bob Lewis played basketball for Stanford coach Everett Dean and played three years for the Indians.
Lewis was noted as a strong defensive player during his time in Palo Alto. In addition to basketball, Lewis was a standout tennis player at Stanford. Lewis graduated with an engineering degree and went into a career in the aerospace industry.
Bob Lewis died on April 11, 2012 at his home in Tucson, Arizona.
