18. Ty Cobb
The first athlete on this list to fight in World War I, Ty Cobb was an outstanding baseball talent. Nicknamed ‘The Georgia Peach,’ he spent the majority of his career with the Detroit Tigers, before finishing up with the Philidelphia Athletics. Furthermore, he set 90 MLB records, including the most home runs in the division’s history.
In 1918, he enlisted in the Army and was assigned to the Chemicals Corps, becoming the captain of his unit. During a training session, something went terribly wrong and the majority of his troop had their lungs poisoned, after contracting tuberculosis. Cobb was lucky to survive and would return to baseball in 1919.
