rohydride chemistry, the London-born chemist is known for theoretical and experimental work on the role of steric strains in determining chemical properties of organic compounds and for his quantitative approach to aromatic substitution reactions. A member of the National Academy of Sciences, the American Academy of Arts and Sciences, and the American Chemical Society, Dr. Brown was the 1968 recipient of the Linus Pauling Medal—the first non-Nobel Prize winner to be so honored. Dr. Robert J. Huebner, chief of the viral carcinogenesis branch of NIH's National Cancer Institute, received the award "for contributions to the modem understanding of viruses and their role in the induction of diverse diseases/' Leading proponent of the theory that cancer can be caused by viral infection, virologist Huebner also played major roles in the discovery of adenoviruses and in development of the first commercial adenovirus vaccine for preventing acute respiratory disease. Physicist Wolfgang K. H. Panofsky of Stanford University was chosen "for classic experiments probing the elementary particles of matter" and for contributions to the technology of particle physics. Known for his work on pi-mesons—including the first quantitative determination of the mass difference between charged and neutral mesons—Dr. Panofsky has been director of the Stanford Linear Accelerator Center since 1961. Dr. William Feller, professor of mathematics at Princeton University, was singled out for contributions to pure and applied mathematics, notably in the field of probability, and for pioneering in the establishment of Mathematical Reviews. Awards also went to Dr. Ernst Mayr of Harvard's Museum of Comparative Zoology and to Jack S. Kilby of Texas Instruments. Dr. Mayr received the medal for contributions to biogeography, for the study of birds, and for his work on the evolution of animal populations. Mr. Kilby, an electrical engineer, was honored for inventing and developing integrated electronic circuits.
WEST GERMANY:
Complex Quite Simple Months of speculations over who will gain control of Chemische Werke Huels have ended with a complex exchange of financial holdings among the major West German chemical companies. Involved in the reshuffle are BASF, Bayer, Hoechst, energy giant VEBA, and several smaller chemical firms. With the swap in participations: 14

• Bayer obtains unquestioned control of Huels, a major producer of plastics and other products, plus full ownership of synthetic rubber maker Synthese-Kautschuk-Beteiligungs (SKB). • Hoechst now has the majority interest in dye and drug producer Cassella Farbwerke Mainkur. • BASF increases its share in lacquer producer Herbol-Werke HerbigHaarhaus to nearly 100%. Negotiations between Bayer and Hoechst, both major shareholders in Huels, over control of the firm had been under way for some time (C&EN, Nov. 4, 1968, page 2 3 ) . Until now Huels stock was held by Chemie-Verwaltungs ( 5 0 % ) , Hibernia (25%), and Bayer (25%). Bayer and Hoechst held shares in Chemie-Verwaltungs. Early in 1967 Bayer increased its interest in Chemie-Verwaltungs. Hoechst countered, however, in fall 1967 with an increase in its stake in Chemie-Verwaltungs, blocking any attempt by Bayer to take control of Huels. For bowing out of Huels, Hoechst receives the interests of BASF and Bayer (totaling 50.49%) in Cassella and will now have the majority, 75.59%, of Cassella. In return, Bayer will receive half of Hoechst's 51.42% interest in Chemie-Verwaltungs, Frankfurt/Main. The other half will go to the Hibernia/ VEBA-Chemie group of companies. As a result, Bayer and Hibernia/ VEBA-Chemie together will hold more than 70% of Chemie-Verwaltungs. Bayer, which already had about 20% of the firm, will have the majority. Bayer will also take over Hoechst's 50% interest in SKB, Frankfurt/Main, for $12.3 million. As Bayer already holds 50% of SKB, the rubber company will become a wholly owned subsidiary of Bayer. This gives Bayer a 50% interest in West Germany's only other synthetic rubber producer, Buna-Werke Huels, Marl, in which
SKB had a 50% interest (the other half is held by Chemische Werke Huels and will remain with C W H ) . In return for its interest in Cassella, taken over by Bayer to pass on to Hoechst, BASF will receive Bayer's 25.6% interest in Herbol-Werke Herbig-Haarhaus, Cologne. BASF already owns about 72% of the firm's $2.8 million capital. In addition BASF will get $12.7 million from Bayer.
METALS:
Interest at Engelhard Anglo American Corp., a South African mining and finance company, has gained effective control of precious metals giant Engelhard Minerals and Chemicals Corp. (EMC), Newark, N.J., through an international sale of stock. With $1.33 billion in sales in 1968, EMC is a kingpin not only in refined metal production, much of it for the chemical industry, but also in metal merchandising. EMC is a combination of three firms merged in two different transactions during the 1960's. Engelhard is the parent refining company, a family concern headed by Charles W. Engelhard. In 1967 Engelhard absorbed Minerals & Chemicals Philipp, which was formed 10 years ago from nonmetal mining firm Minerals & Chemicals and metal merchant Philipp Bros. The current transaction involves two intermediate business entities between EMC and Anglo American. The first is a newly formed company in Europe controlled by Anglo American. The name and location have not yet been revealed, according to EMC president Milton F. Rosenthal. Mr. Engelhard states that he and his family have sold to this intermediary part of their shareholdings in a second company, Engelhard Hanovia, Inc., which has an effective controlling interest in EMC.
