Neil 
Armstrong, who on July 20, 1969, became the first human to set foot on the Moon, died on Aug. 25 in Cincinnati at age 82. He succumbed to complications following cardiovascular procedures, according to his Los Angeles Times obituary. “Neil was among the greatest of American heroes—not just of his time, but of all time,” said President Obama in a statement. “When Neil stepped foot on the surface of the moon for the first time, he delivered a moment of human achievement that will never be forgotten.” Born on Aug. 5, 1930, near Wapakoneta, Ohio, Armstrong was a naval aviator who completed nearly 80 combat missions during the Korean War. He later flew pioneering high-speed research aircraft, such as the X-15, prior to joining the astronaut program in 1962, states his NASA biography. Armstrong was the spacecraft commander for NASA’s Apollo 11 lunar landing mission, which included fellow astronauts Buzz Aldrin and Michael Collins. Armstrong immortalized the following words as he stepped onto the Moon’s surface from the Apollo 11 lunar module: “That is one small step for man, one giant leap for mankind.”
