At the 1947 World Championships, Button was second behind rival Hans Gerschwiler following the compulsory figures part of the competition, with 34.9 points separating them. He won the free skating portion, but Gerschwiler had the majority of first places from the judges, three to Button's two. Button won the silver medal at his first World Championships. It was the last time he placed lower than first in competition. At the competition, Button was befriended by Ulrich Salchow. Salchow, who was disappointed when Button did not win, presented him with the first International Cup Salchow had won in 1901. Button later passed on this trophy to John Misha Petkevich following the 1972 Olympics and World Championships. Acknowledging that Gerschwiler had a better understanding of outdoor ice, Button decided to spend some time training outdoors on the Lake Placid club tennis courts.
