Happy birthday today (Saturday) to two Olympic champions who competed in a total of seven Olympic Games.

One of these two champions was 21 when the other person was born.

Our birthday athletes earned a total of two Olympic gold medals during their careers.

Both birthday athletes set world records.

The younger of the two won three World Championship gold medals, two World Championship silver medals, one World Championship bronze medal, and one World Indoor gold medal.

You might already know that the older individual was born 76 years ago today, but died at the age of 59.

Please name both Olympic champions.
