In 1935, Robinson graduated from Washington Junior High School. He then entered Muir Tech (now called John Muir High School). Seeing that Robinson was good at sports, his older brothers Mack (himself a good athlete and silver medal winner at the 1936 Summer Olympics) and Frank inspired Jackie to follow his interest in sports. At Muir Tech, Robinson played several sports at the varsity level. Robinson lettered in four of them: football, basketball, track, and baseball. He played shortstop and catcher on the baseball team, quarterback on the football team, and guard on the basketball team. With the track and field team, he won awards in the broad jump. He was also part of the tennis team.
