Mark Spitz, winning 7 medals, then a new record. This record has since been pasted by Alexander Dityatin in 1980 and Michael Phelps in 2004 and 2008; both athletes have won 8 medals in a single Olympics. But Spitz would retain the title of most gold medals until 2008 as Dityatin won 3 gold 5 silver and a bronze in 1980. Phelps won 8 gold medals in a single Olympic game in 2008, which set a new record of most gold medals in a single Olympic.
No, Alvin Kraenzlein did that before Owens did.

Gaétan Boucher, a Canadian legend, in my opinion :) He won 2 of his gold medals in a single olympics game (1984 I am 95% sure)
No they did not win any medals or advance into finals
