Age: 37 (June 19, 1903 – June 2, 1941)
Cause of Death: ALS

Gehrig remains one of baseball’s most iconic players almost 80 years after his last game. He tore up the majors in the 1920s and 30s, finishing his career with a .340 lifetime average. Gehrig played a whopping 2,130 consecutive games — a record that seemed unbreakable at the time.

But in 1939, something wasn’t right. Gehrig was batting just .143 eight games into the season, and decided to bench himself for the good of the team, missing his first game in 14 years. Gehrig would never play again, as he soon found out he was suffering from ALS. That Fourth of July, he gave his famous speech, and was inducted to the Hall of Fame in a special election that December. Baseball writers waived the typical six-year wait period so that Gehrig would live to see his induction. He passed away in 1941, less than three weeks shy of his 38th birthday.
