The World Confederation for Physical Therapy held its first formal meeting in Copenhagen. Mildred Elson, APTA’s first executive director, was elected to serve as WCPT’s first president. Five years later, in 1956, APTA would cohost the second WCPT World Congress in New York City, where Elson would be one of the dignitaries on hand as WCPT honored Jonas Salk for the introduction of his widely acclaimed Salk vaccine for polio the previous year.
