Hungarian dancer, choreographer, teacher, and ballet master. Raised as a foster child, he discovered ballet through his godmother who worked as a cleaning woman for the ballet master Jakab Holczer. Holczer adopted him as student and virtual stepson. Nádasi also studied with Henrietta Spinzi and Nicholas Guerra in Hungary and later with Cecchetti in St Petersburg. In 1910 he toured Russia with a group organized by Holczer. From 1913 to 1921 he was a dancer with the Budapest State Opera Ballet, becoming the company's first male soloist. After leaving the opera house, he embarked on more than a decade of European touring, performing classical ballet as part of a variety bill with his wife, Marcelle Vuillet-Baum. In 1936 he returned to the Budapest State Opera, becoming ballet master and eventually artistic director (1959–61). He was the first director of the Budapest State Ballet Institute (from 1950) and was responsible for training a generation of leading Hungarian dancers. He was also head of a group of teachers who produced Method of Classic Dance (1963), one of the standard works of classical ballet training. His works for the Hungarian State Opera Ballet include Sylvia (1943), Le Spectre de la rose (1948), and The Birthday of the Infanta (1959). Merited Artist of the Republic and Order of Merit, first class.
