By the time of Frederick Winslow Taylor's death, the gospel of industrial efficiency preached by American scientific managers was commonplace on both sides of the Atlantic. In the following years of world war, reconstruction, and adjustment, scientific management attracted a new generation of advocates and practitioners, many of whom would have perplexed and shocked Taylor and his immediate circle. Of the entrepreneurs of scientific management who succeeded Frank Gilbreth, Harrington Emerson, Richard Feiss, and other pioneers, none was more successful than Charles Eugene Bedaux (1886-1944). Unlike Taylor and his colleagues, Bedaux was and still is a mysterious figure. Secretive to a fault, he avoided professional contacts, refused to write for popular or technical journals, and spurned publicity. Yet he was a master salesman whose operations were global in scope and impact. Only in recent years, with the discovery of the papers of the British Bedaux Company, is it possible to gauge the impact of Bedaux and his extraordinary career.
