Joseph Innarone and John Tackray are two former members of the DuPont dye business that experienced its golden age after World War II and was sold off in 1979, marking the visible onset of the decline of the U.S. synthetic dye industry. The authors are not research chemists. For the entire period covered by the book, they both held different jobs in the dye business, spanning technical service, sales, and business management. In course of their various assignments that started for both of them as trainees in the Technical Laboratory, the authors acquired substantial knowledge of dye innovations and the business of selling dyes. Rather than attempting a scholarly history (only five sources are cited), the authors offer their own personal history of Du Pont’s dye business. Their story is valuable for anyone who wants to gain a deeper understanding how DuPont became an innovator in the synthetic dye industry yet in the 1970s could no longer compete successfully with foreign rivals. Du Pont exited the industry in 1979 as later did all other U.S. headquartered firms.
