Otto Bayer (November 4, 1902 in Frankfurt – August 1, 1982 in Burscheid) was a German industrial chemist at IG Farben who was head of the research group that in 1937 discovered the polyaddition for the synthesis of polyurethanes out of poly-isocyanate and polyol.
Dr. Bayer was not related to the founding family of Bayer Corp. Today polyurethanes are ubiquitous throughout modern life. He was a member of the board of directors and of the supervisory board of Bayer, and was also vice chairman of the supervisory board of Cassella in the 1950s.
