Which years did Dick Button win gold in figure skating?

Dick Button is well-known for his achievements in figure skating, particularly for winning the gold medal in the men's singles at the Winter Olympic Games. He achieved this distinguished honor in 1948, held in St. Moritz, Switzerland, and again in 1952 at the Games in Oslo, Norway. His victories in these years were pivotal not just for his career but also for the sport itself, as he was the first male figure skater to land a double axel in competition, which showcases his influence on the evolution of figure skating. The other answer choices represent years when other skaters competed, but they do not correlate with Dick Button's Olympic gold medal achievements.
