Katie Ledecky won the 800-meter freestyle in world record time at the Rio Olympics on Friday night, the first time in 48 years that a female swimmer has swept the 200, 400 and 800 freestyles.

Ledecky, a 19-year-old from Bethesda, Maryland, matched the feat of Debbie Meyer, also a Maryland native who won all three events at the 1968 Mexico City Games.

Meyer was a 16-year-old high school student when she became the first swimmer to win three individual golds in a single games. She set Olympic records in each of the events. In 1968, the 200 and 800 freestyles for women were added to the Olympic program for the first time.

Meyer and Ledecky have met before, and Meyer attended the U.S. trials in July, bringing her three golds and letting youngsters try them on and pose for photos.

Meyer, who turns 64 on Sunday, later opened her own swim school in California and had a license plate reading "3GOLD68."
