Lou Gehrig, one of baseball’s greatest players, was forced out of the game at age 35 by a fatal nerve disease that would eventually bear his name. After playing 2,130 consecutive games for the New York Yankees, a streak that stood as a record for more than 60 years, Gehrig’s body began failing him in ways no one could explain. Within two years of his last game, he was dead.
The Decline No One Could Explain
By the 1938 season, something was clearly wrong. Gehrig’s batting average had already slipped to .295, a respectable number for most players but a sharp drop for a man who had been one of the most feared hitters in baseball. Teammates noticed he was stumbling on the field, losing coordination, and lacking his usual power. Still, he hit 29 home runs that year and played in all 157 games.
The 1939 season was different. In eight games, Gehrig managed just four hits in 28 at-bats, a .143 average with zero home runs. He couldn’t grip the bat properly, couldn’t run the bases, couldn’t make routine plays at first base. On April 30, 1939, he pulled himself from the lineup. That was his last Major League game.
Diagnosis at Mayo Clinic
Gehrig traveled to the Mayo Clinic in Rochester, Minnesota, where doctors examined him over several days. On June 16, 1939, his 36th birthday, he received the diagnosis: amyotrophic lateral sclerosis, or ALS. At the time, doctors already understood the disease was progressive and fatal. Historical cases from that era showed an average survival of about two years after symptoms appeared, with some patients living as few as five months and others lasting up to nine years.
There was essentially nothing medicine could offer. Gehrig received experimental vitamin E injections, a treatment that had shown promise in animal studies after the compound was isolated in the 1920s. It did not slow his decline.
How ALS Destroys the Body
ALS attacks the nerve cells that control voluntary movement. These motor neurons, which run from the brain through the spinal cord and out to the muscles, gradually die off. As they disappear, the muscles they control weaken, shrink, and eventually stop working entirely. The disease typically progresses from limb weakness to difficulty speaking and swallowing, and finally to respiratory failure as the muscles needed for breathing give out.
The brain’s signaling system relies on a balance between excitatory and inhibitory chemical signals. In ALS, that balance breaks down. Excess excitatory signaling can become toxic to motor neurons, essentially overstimulating them to death. Inflammation in the brain and spinal cord compounds the damage. The average survival after symptoms first appear is three to five years.
The “Luckiest Man” Speech
On July 4, 1939, the Yankees held “Lou Gehrig Appreciation Day” at Yankee Stadium. Between games of a doubleheader, Gehrig stood at a microphone on the field and delivered what became one of the most famous speeches in American history. Visibly weakened, he told the crowd of more than 60,000 that he considered himself “the luckiest man on the face of the earth.” He never played again.
Gehrig continued working for a time, accepting an appointment to the New York City Parole Commission, but his condition deteriorated steadily. Walking became difficult, then impossible. On June 2, 1941, less than two years after his diagnosis, Lou Gehrig died at his home in the Bronx. He was 37 years old.
The Disease That Bears His Name
Gehrig’s public battle with ALS gave the disease a human face at a time when most people had never heard of it. Almost immediately, the condition became known as “Lou Gehrig’s disease,” a name still widely used in the United States. His diagnosis and rapid decline brought public attention to a disease that remains incurable more than 80 years later, though modern treatments can now extend survival for some patients.
Did Gehrig Actually Have ALS?
A surprising question emerged decades after his death. Researchers at Boston University discovered a link between repetitive head trauma and a motor neuron disease that closely resembles ALS but appears to be a distinct condition. They named it chronic traumatic encephalomyelopathy, or CTEM.
Gehrig’s history makes this finding particularly striking. He played football at Columbia University before joining the Yankees. During his baseball career, he suffered at least five documented concussions and was once knocked unconscious for five minutes after being hit in the head by a pitch while not wearing a helmet. He played the next day. The risk of ALS among collision sport athletes is estimated to be at least eight times higher than in the general adult male population.
Researchers have raised the possibility that Gehrig may have suffered from this trauma-related motor neuron disease rather than classical ALS. Without the ability to examine his brain and spinal cord tissue, there is no way to know for certain. Either way, the disease killed him the same way: by systematically destroying the nerve cells that let him move, breathe, and ultimately stay alive.
