Galen and Pharmaceutical Technology

Using certain examples we have shown, that Galen took the properties of the used components and their components into consideration, offered sensible ingredients combinations and blends, and prepared a dosage form, capable of implementing its pharmacological action. The analysis of the materials gave grounds to consider Galen not only as an outstanding doctor, but one of the first manufacturing chemist.

Chemistry, Color, and Art

Artists' colors have been intertwined with chemistry from antiquity, both in the extraction of them from raw materials and their production by the 'manufacturing chemists' of their day. In our own time, not only has chemistry made possible the enormous expension of the artist's palette, but also has provided methods to study it scientifically with a view to restoration, preservation, authentication, and understanding of works of art.

The Rise of a Northern Musical Élite

NORTHERN MUSICIANS of national and international stature emerged on a proportionate scale quite abruptly in the nineteenth century. They rose on the back of unprecedented and spectacular technological and industrial advance. The North of England the third of the country beyond the Trent in terms of nationally recognized musical talent now at least 'punched its weight'. Sir Thomas Beecham and Sir Adrian Boult epitomize this rise. Both men were born in the North in the later nineteenth century, both received their musical education and made their careers mainly outside the North, and both came from wealthy urban-industrial families. Beecham's father was a manufacturing chemist (and mayor) at St Helen's, Boult's father, from a deep-rooted Chester family, made his fortune as an oil merchant in Liverpool. 1 Other northern musicians of distinction generally came from far less affluent families; but they rose against a background of immense and relatively recent regional prosperity and urban growth. It was not only 'elite' or classical musicians like Beecham and Boult who were now coming disproportionately out of the North: more popular music-makers and in particular the brass bands rose strongly in northern industrial society. The brass bands have been described as 'the most remarkable working-class cultural achievement in European history';2 but in spite of their wide geographical spread throughout England, they showed a marked northern concentration: 'It is undeniable that the movement was a northern phenomenon'. Certainly the prizewinning bands were disproportionately from the textile towns of Yorkshire and Lancashire.3 They rose with the great festivals of choral classical music in the southern Pennines (the first of Bradford's renowned musical festivals was held in 1853, and the Black Dyke brass band was formed in the neighbouring textile town of Queensbury the following year) and although their social-class base and musical style were sharply

Leonard Harrison Matthews, 12 June 1901 - 27 November 1986

Leonard Harrison Matthews was born at Clifton, Bristol, and was the eldest child of Harold Evan Matthews, a manufacturing chemist who had studied at the London School of Pharmacy where he had won prizes and medals, and Ruby Sarah Harrison, formerly a pharmacist. Known to many as ‘Leo’, and to others as the intrepid explorer ‘El-Aitch-Em’, he had earlier in his career been nicknamed ‘Matt’, and then ‘Hyaena’ Matthews. He was the last of the great travelling naturalists of his day having visited South America, the Falklands and South Georgia, the Antarctic and the Arctic, Europe and Africa to observe and dissect animals varying in size and diversity from copepods to whales. His extensive knowledge of animals and their habits was incorporated in a long series of research papers and popular books that have already become valued collectors’ items. He was never better than at meetings at the London Zoo when talking on animals newly introduced to the Collections or fostering discussion on papers read to the Zoological Society. No laboratory experimentalist, he frequently claimed that the animals themselves performed naturally all the experiments that he would wish to conduct. When in detective mode, and wearing his cape and carrying a swordstick, he always seemed to the writer an incarnation of Chesterton’s The man who was Thursday .

Stability-Indicating High-Pressure Liquid Chromatographic Assay for L-Lysine

Abstract A high-pressure liquid chromatographic method for the assay of L-Lysine is described. L-lysine was derivatized by reacting with 2,4-dinitrofluorobenzene. A fixed wavelength detector (254 nm) and a LiChrosorb RP-18, 10 μm, Hibar-II column from MCB Manufacturing Chemists, Inc., was employed. The method is simple, precise, accurate and stability-indicating.

Toxic substances law: a quiet first year

Last year C&EN polled key industry executives about how the then newly enacted Toxic Substances Control Act (TSCA) would affect the chemical industry (Jan. 3, 1977, page 15). Most of them expressed guarded optimism about the new law, but some did have serious misgivings. One firm, in fact, which originally supported toxic control legislation, no longer thought it necessary in light of other environmental laws passed in recent years. Now, after a little more than a year, C&EN again has asked some of the same industry leaders for their assessment of how TSCA is progressing and how well the Environmental Protection Agency is administering the law. Overall I'd have to say that things are going more reasonably and more realistically than we would have expected, observes George Dominguez, Ciba-Geigy Corp.'s director of government relations, and chairman of the Manufacturing Chemists Association's regulatory advisory committee. We're kind of happy that EPA's apparently taken cognizance ...
