After exploratory inquires by Wallace Waterfall, Floyd Watson, and Vern Knudsen (pictured on the left), a group of some 40 scientists and engineers interested in acoustics met on 27 December 1928 at the Bell Telephone Laboratories in New York, NY, to consider forming a scientific society. Plans developed rapidly and the Acoustical Society of America was formally organized and held its first meeting 10-11 May 1929 with a charter membership of about 450.
