description: "Joris Gerhard Keizer is a retired butterfly swimmer from the Netherlands, who competed for his native country at two consecutive Summer Olympics, starting in 2000 in Sydney, Australia. There he was eliminated in the semifinals of the 100m butterfly, and finished in fourth place with the men's 4×100 medley relay team. A year earlier, Keizer won the bronze medal in the 50m butterfly at the 1999 FINA Short Course World Championships. He retired from the sport after a disappointing appearance at the 2004 Summer Olympics in Athens, Greece."
