Henry Louis "Lou" Gehrig (June 19, 1903 – June 2, 1941), was a Major League Baseball first baseman. He played his 17-year baseball career entirely with the New
York Yankees (1923-1939). His career was cut short by ALS, now commonly known
as Lou Gehrig’s disease. Gehrig holds the record for most career gland slams at
23 total. He was elected to the Baseball Hall of Fame in 1939. In 1941 Lou Gehrig
died of the neuromuscular disease at the age of 37. He was voted the greatest first baseman of all time in 1969 by the Baseball Writer’s Association.

Dale Earnhardt, Sr. (April 29, 1951 – February 18, 2001). The stock car

The Boston Marathon is an annual event hosted by the city of Boston, Massachusetts
on Patriot’s Day, the third Monday of April. It began in 1897 and was inspired by the success of the first modern-day marathon competition in the 1896 Summer Olympics. The Boston Marathon is the world’s oldest annual marathon and ranks as one of the world’s best-known road racing events. The first marathon started with 18 participants, and today it attracts an average of 20,000 registered participants each year. It is the most widely viewed sporting event in New England.
