Born in 1903, Henry Louis “Lou” Gehrig grew up to become a man who is widely considered to be the best first baseman in baseball history. Lou was first drafted by the New York Yankees in 1923, plucking him from a college he had been attending on a football scholarship. This lefty was dubbed “The Iron Horse” due to his incredible skills at bat as well as his durability. After he retired in 1939 due to ALS, this two-time MVP was elected into the Baseball Hall of Fame. His number, 4, was also the first to ever be retired in MLB history. After his baseball career was over, Lou Gehrig accepted a job as Parole Commissioner because it provided a public service. He died in 1941, three years after onset, and two years after retirement. source (http://en.wikipedia.org/wiki/Lou_Gehrig)
