Although Jenkins used mechanical rather than electronic technologies and is one of the lesser-known pioneers of television, his contributions were still of great importance. He acquired over 400 patents in his lifetime, in such diverse areas as paper containers, automobiles, propellers, and time-lapse photography. Seventy-five of those patents were dedicated to mechanical television alone. Jenkins was the founding member and first president of the Society of Motion Picture Engineers, now the Society of Motion Picture and Television Engineers (SMPTE).
C. Francis Jenkins died in June of 1934.
