Limbert was then selected to serve the highest post in all of the YMCA movement. In 1952, he was named Secretary General of the World Alliance of YMCAs in Geneva, Switzerland. During his tenure, the YMCA celebrated its centennial in 1955, and Limbert visited many YMCAs in over 60 nations, including Britain, France, and in Africa.
After his term ended, Limbert traveled, lectured and wrote articles dealing with YMCA history. In 1985, at age 88, he was named as the first inductee into the YMCA Hall of Fame. Limbert was also named as the association's most notable living leader, a "position" he held until his death at the age of 101 in 1998.
