Luxembourg first sent an official team to the Olympics at the 1912 Games in Stockholm. They sent 21 athletes to compete in gymnastics and athletics. They won no medals. But the first athlete born in Luxembourg to compete at the Olympics was Michel Théato who won gold in the marathon at the 1900 Games in Paris. Michel lived in Paris and, at the time, was considered part of the French Olympic team.
Time Travel
By most accounts, the first time basketball was officially played at the Olympics was in 1936 in Berlin, with only amateur players-- and at that time, this meant men only. In 1992, professionals were allowed to compete for the first time.
It was the first time that women were allowed to compete in the games and Charlotte Cooper was the first to win the gold medal at tennis.
So they can compete in different places each time
The first Olympics started at 1739AD The Olympics (Summer or Winter) occurs every four years, but the Summer and Winter Olympics are offset by two years so that an Olympic competition actually happens every two years. Because each country must qualify their prospective athletes in time to compete in a given Olympics, competitions are held year-round.
19 women competed in three sports (golf, croquet, tennis) at the 1900 Games in Paris, the first Olympics where women competed.
They can compete in the Olympics 1-2 times usually. Your body gets too weak by the time you reach above 25 to be good enough for Olympics compared to the other younger girls that are waiting to go.
