Besides companies specifically mentioned in the text, the authors are indebted for donations of materials to the American Cyanamid Company, the Geigy Company, and the Pennsylvania Salt Manufacturing Company. They also wish to express indebtedness to W. E. Baier, of the California Fruit Growers Exchange, for arranging to process the DDT-treated lemons and oranges, and to M. Elliot Miller and R. C. Blinn of these laboratories for most of the analytical work.. 

Recalling that parathion was developed as an insecticide by aayer in 1944 and that the Geigy Company were developing the carbamate anticholinesterases for this purpose in the late 1940s, we see that the 1950s were entered with (including toxaphene) no less than four new classes of chlorinated insecticides and two new classes of anticholinesterase insecticides - a truly unique situation ...

Mitln FF, is a sulfonate compound developed by the J. R. Geigy Company in Switzerland and Introduced to the trade in 1939 (Moncrieff, 1950). Essentially, Mitin FF is a water-soluble colorless dyestuff that will exhaust onto wool from an aqueous solution in a manner similar to a weak acid dye. When applied at temperatures above 60°C, Mitln FF is fast to washing and is not affected by light, hot pressing, or drycleaning. 

The chemical industry manufactures a large number of antioxidants (qv) as well as uv stabilizers and their mixtures with other additives used to facilitate resin processing. These companies include American Cyanamid, BASE, Ciba—Geigy, Eastman Chemical, Elf Atochem, Enichem, General Electric, Hoechst—Celanese, Sandoz, and Uniroyal, among others. The combined market for these products in the United States exceeded 900 million in 1994 and will reach 1 billion in the year 2000. 

Commercial BMI Resins. Since the late 1960s, bismaleimide resins have been commercially available. The first company in the marketplace was Rhc ne Poulenc Chimie, Erance. Several others, Technochemie, Germany CIBA GEIGY, Switzerland DSM, The Netherlands, BASE, West Germany Mitsubishi Gas Chemicals and MitsuiToatsu, both of Japan Reichhold and Polyorganics from the United States and Shell Chemical Company, United States (through the acquisition of Technochemie by Deutsche Shell AG), followed. Some of them lost interest in this speciaUty market sector. Table 13 indicates the BMI resins available at the end of 1992. No reference is made to prepreg systems available from various sources. A complete Hst of available products and information on any particular material should be obtained from the suppHers. 

In the USA producers included Eastman Kodak (Tenite PTMT), General Electric Corporation of America (Valox), and American Celanese (Celanex). In Europe major producers by the end of the decade were AKZO (Amite PBTP), BASF (Ultradur), Bayer (Pocan) and Ciba-Geigy (Crastin). Other producers included ATO, Hills, Montedison and Dynamit Nobel. With the total Western European market at the end of the decade only about 7000 tonnes other companies at one time involved in the market such as ICI (Deroton) withdrew. 

A premium antiscalent product in this group is Flocon 100 from Great Lakes Chemical Corporation (originally the brand was owned by Pfizer, then Ciba-Geigy, then FMC). Flocon 100 is a 35% w/w, 2,000 MW acrylic acid polymer. An alternate and much more concentrated product is Good-Rite K-752, a 62.5% w/w, 2,100 MW acrylic acid polymer from Noveon, Inc. (formerly BF Goodrich Company). 

National market shares shifted as fast as fashion taste. Five years after the London exhibition, another international fair was held in Paris. By then, the dyes market had tripled in value, although French dye companies—like some of their colors—were fading. Their chemists were emigrating to Switzerland where future chemical giants, including Novartis forerunners, Ciba and Geigy, would flourish. 

Richard C. Honeycutt, Ph.D., was born in Newport News, VA, in 1945. He attended Anderson University in Anderson, IN, from 1963 to 1967 and earned an A.B. in Chemistry. He received his Ph.D. in Biochemistry from Purdue University in 1971 and served as a Postdoctoral Fellow from 1971 to 1973 at the Smithsonian Institution s Radiation Biology Laboratory. Dr. Honeycutt worked as a Senior Chemist at Rohm and Haas Company from 1973 to 1976 and as a Senior Metabolism Chemist at Ciba Geigy from 1976 to 1989. Currently, he is President of the Hazard Evaluation and Regulatory Affairs Company, Inc., which he founded in 1990, and is an analytical biochemist and field research specialist/consultant engaged in exposure assessment of pesticides to humans and the environment. 

The medical success of these drugs gave new emphasis to the pharmaceutical industry, which was boosted further by the commencement of industrial-scale penicillin manufacture in the early 1940s. Around this time, many of the current leading pharmaceutical companies (or their forerunners) were founded. Examples include Ciba Geigy, Eli Lilly, Wellcome, Glaxo and Roche. Over the next two to three decades, these companies developed drugs such as tetracyclines, corticosteroids, oral contraceptives, antidepressants and many more. Most of these pharmaceutical substances are manufactured by direct chemical synthesis.

Paul Hermann Muller received a degree in chemistry and worked for the J. R. Geigy Corporation, which later became part of Novartis (McGrayne 2001). Geigy specialized in dyestuffs for woolens. Chemists at the company discovered a chlorinated hydrocarbon compound that protected woolens from clothes moths, but it was a stomach poison. Geigy then searched for other insecticides that killed other pests. Natural insecticides made from plants include pyrethrum from chrysanthemum, rotenone from a tropical...
