Science Marketing Notes
British postage stamps honor chemists Conformational analysis—synthesis— chromatography—crystallography. These four areas of chemistry are the subjects of stamps being issued this week by the British post office. The new stamps represent the chemical achievements of four British Nobel Prize winners, all members of the Royal Institute of Chemistry, whose centenary the stamps are designed to commemorate. An 8%-pence stamp with a design based on conformational analysis depicts the chemical structure of a steroid. It honors Sir Derek Barton, who worked with steroids to pioneer his theories in conformational analysis that have simplified considerably the intricate synthesis of complicated biological substances. For his work, Barton won the 1969 Nobel Prize in Chemistry. Synthesis is depicted on a 10-pence stamp with the structure of vitamin C. Sir Norman Haworth is the chemist honored. He and his research group deduced the structure of vitamin C and produced the first synthetic vitamin. For this achievement, he shared the 1937 Nobel Prize with Paul Karrer of Austria for independent work in vitamins. Chromatography is the subject of an 11-pence stamp. It honors Dr. A. J. P. Martin and Dr. R. L. M. Synge, who pioneered gas chromatography. They were the 1952 recipients of the Nobel Prize. Depicted on the stamps along with the colored spots is the trace obtained by Synge when separating amino acids on a column of starch. X-ray crystallography is represented on
a 13-pence stamp honoring W. H. and W. L. Bragg, who pioneered the technique using salt. For their work, they won the 1915 Nobel Prize in Physics. Sir Lawrence Bragg was specially elected an honorary fellow of the Royal Institute of Chemistry. The event being commemorated by the stamps took place on March 29,1877, in London, with the founding by Chemical Society fellows of the Institute of Chemistry of Great Britain & Ireland—in 1949 renamed the Royal Institute of Chemistry. The independent professional body, as stated in its 1885 Royal Charter, exists to provide a means of recognizing those who have been trained properly and proved competent to practice chemistry. The institute provides an advisory service for the profession on behalf of its members, who work in industry, education, and public service. All public analysts, for example, are required by law to hold an institute qualification of Mastership in Chemical Analysis. The institute has 29,000 members, who use the designatory letters LRIC, MRIC, and FRIC for licentiates, members, and fellows. Fellows and members also use CChem for Chartered Chemist. This designation is equivalent in Great Britain to Chartered Accountant, Chartered Surveyor, and the like. The institute is celebrating its centennial year with the theme "Chemistry in our lives." Exhibitions, lectures, television programs, competitions, and company and laboratory visits for school children are planned. •
