BROOKLINE, Massachusetts -- Monday marks 100 years since the birth of the 35th president, John F. Kennedy.
Kennedy was born on this day in Brookline, Massachusetts, in 1917. He attended Harvard University, served in the Navy during WWII, and served in both the House and Senate. Kennedy won the presidency in 1960.
The JFK Library is marking the day with a birthday card open for anyone to sign and leave a message regarding how Kennedy inspired them. Leaders say it's a chance to reconnect with Kennedy's values to serve the United States and make the world a better place.
Organizers are also celebrating his birthday with a cake, and handed out slices for 1,000 guests.
