Gary Lewis

Gary Roger Lewis (February 22, 1942 – December 12, 1986) was an American professional football running back in the National Football League (NFL). He played seven seasons for the San Francisco 49ers from 1964 to 1969 and New Orleans Saints in 1970.

Lewis was one of three 1964 San Francisco 49ers teammates who died of amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, a rare ailment with an incidence estimated at 1 per 50,000 individuals in the general population. Others 49ers stricken by the disease included contemporaries Bob Waters and Matt Hazeltine and — a generation later — wide receiver Dwight Clark.
