Richard F. Heck (bom 1931) was a student of Saul Winstein (UCLA) and Vladimir Prelog (ETH Zurich). He started mechanistic work on homogeneous catalysis in 1956 when he entered Hercules Inc. (Wilmington, Del., USA) as a research chemist. He pioneered the elucidation of reaction mechanisms of organometallic processes, e. g., hydro-formylation and Ziegler-Natta polymerization, and published a number of key papers about the chemical and mechanistic backgrounds of these reactions. He was a chemistry professor at the University of Delaware from 1971 until his retirement in 1989. For the Heck reaction the reader is referred to Section 3.1.6. 

It was under the impulse of the First World War that the manufacturing of synthetic chemicals, already well established in Europe, began on a large scale in the United States. Even before the United States entered the conflict, the war transformed the chemical industry. Explosives makers like DuPont and Hercules ran plants to the limit to fill European orders, while a British blockade of German exports impelled the sudden launch into production of chemicals that had previously been imported. War-inflated profits were plowed into new plants, capital flooded in from investors, and by November 1917, the secretary of the American Chemical Society could say that the country s chemists had accomplished within two years what it took Germany forty years to attain. 10... 

Sung Gun Chu received his B.S. from Han Yang University, Seoul, Korea and his Ph.D. from the University of Texas (1978) in Polymer Physical Chemistry. He joined Hercules Incorporated in 1981 and is presently a Research Chemist in the Adhesives Laboratory at the Hercules Research Center. 

Marlene Jones received her B.A. degree in Chemistry from Thiel College. She joined Hercules Incorporated in 1972 and is currently a Sales Development Supervisor in the Resins Division. Prior to this, Marlene held the position of Staff Chemist in the Adhesives Laboratory at the Hercules Research Center. Her experience in adhesives is primarily in the pressure-sensitive field. 

Two other industrial chemists who worked with developing NIR applications in the 1950s were Robert Goddu of Hercules Powder Company (now Hercules Incorporated) and Kermit Whetsel of Tennessee Eastman. Goddu explored a number of different applications including the measurement of epoxide functionafity and unsaturation in polymers and phenohcs. His review chapter published in 1960 included many of these applications. Whetsel also studied a number of applications including phenols, fuels, and polymers, and included those in a review article published in 1968."... 

Sung Gun Chu, chemist, received a Ph.D. degree in physical polymer chemistry from the University of Texas at Austin in 1978. His main interests are in the property-structure processing relations of polymeric materials, and the rheology of polymers. Since Dr. Chu began work at Hercules in April 1981, he has been involved in the study of adhesives and sealants. He is also involved in the development of new, tough matrix resins for graphite composite applications, has published over 20 papers, and has several patents on adhesives and composite resins. He is presently a Project Leader in Adhesives at the Hercules Research Center.
