on the womens side:
Fanny Blankers-Koen was a Dutch athlete known as "The Flying Housewife" (and also "Amazing Fanny") after winning four gold medals in the 1948 Olympics whilst already the mother of two. Mrs Blankers-Koen won four gold medals, the 100 meters, 200 meters, 80 meters hurdles and 4 x 100 relay. She also held the world high jump and long jump records at the time, but didn't compete in those events in the Olympics. The two winners were both well behind Amazing Fanny's world records, so she would likely have won them as well had she taken part. She was also Dutch shot put champion, and would have walked the pentathlon, except that there wasn't one at the 1948 games.
Could a woman of 30 with two kids win all these events today? I doubt it.
A couple of bits of Fanny trivia. After her Olympic triumph, she was instrumental in having a rival sprinter with the unlikely name of Foekje Dilemma thrown off the Dutch team. She alleged that Dilemma was a man, but there appears to have been no obvious evidence for this. (Unlike the Polish/American sprinter Stella Walsh, who just was a man. When "she" died in 1980, doctors allowed journalists to view the body - which left the matter in little doubt.)
Oh, and a piece of Olympic trivia about that relay. The Dutch team that won it consisted of Xenia Stad-de Jong, Jeanette Witziers- Timmer, Gerda van der Kade-Koudijs and Fanny Blankers-Koen. It's the only time an Olympic relay race has been won by four married women.
