If you consider wining the most medals to be "winning", then it would be Greece - they won 10 Gold 17 Silver and 19 Bronze medals in the 1896 Summer Olympics. The USA won 11 Gold, 7 Silver, and 2 Bronze - so if "winning" is getting the most Gold's, then the USA "won" - albeit with less than half the total medals won by the Greeks.
Note: the medals awarded to the winning athletes were actually silver with runners-up getting a copper medal

== == In the SUMMER Olympics, I think it was Stephanie Rice. Steven Bradbury was the first Australian athelete to win gold in the Winter Olympics. It was for the 1,000 metre short track speed skating in the 2002 games. Australia is the only country in the southern hemisphere to win a gold medal at the Winter Olympics.
I don't know that history has recorded the first woman to compete in the Olympics. History has recorded that the first woman to win a gold medal was Charlotte Cooper of Great Britain who won gold in ladies singles tennis in the 1900 Olympics in Paris. The 1900 Olympics were the second Olympics of the modern era and the first that women were allowed to compete in. Women were not allowed to compete in the first modern Olympics held in Greece in 1896.
There are 97 events in which a country can win a gold medal in the 2014 Winter Olympics. It is possible, though highly unlikely, for one country to win them all.
