John F. Kennedy was one of the most beloved presidents in United States history. The youngest president ever elected, he was born on May 29, 1917, and was 43 years old when he was inaugurated in 1961.

He was assassinated less than three years later on Nov. 22, 1963, at the age of 46, but he has remained a crucial part of American culture memory in the years since. His short time in office is sometimes remembered for its foreign policy challenges, but when most people think of JFK they picture his idyllic family and savor America’s very own version of royalty.

Kennedy would have been 99 years old if were still alive this year. In honor of the anniversary of his birthday, here are some of the most memorable quotes from the former president, courtesy of the John F. Kennedy Presidential Library and Goodreads.
