Abstract :
The year 1968 marks the 20th year of annual Pioneer Awards made by G-AES and its predecessors. The presentation of the bronze plaque has been one of the highlights of the annual NAECON meetings in Dayton, Ohio, every May. The names of the Pioneer Award winners constitute a roster of outstanding contributors to the field of AES. Biographical-historical sketches on the a ward winners have been appearing annually in the TRANSACTIONS since 1956, serving as source material on many of the great advancements in radio navigation and airborne electronics. It is fitting at this time to collect together the names of all past Pioneer Award Winners and present them here.
