“…The senior staff remaining at UCT after Rapson and Carman had transferred to Pretoria, and Newbery had retired, were at first few in number. Pugh, the HoD, was the leading researcher in inorganic chemistry and analysis, Spong (Anderson et al,1957;Du Plessis & Spong, 1959) and Sebba were the physical chemists (Sebba & Sutin, 1952;Sebba, 1962), and Fred Holliman FRSSAf was in charge of organic chemistry; in addition he was instrumental in setting up microbiology and biochemistry at undergraduate level. Of the many new appointments made in the 1950s, the applied chemist Victor Tarica stayed three years, but Prout, Stephen and Pay left only in the 1980s; Campbell remained until 1997.…”

includes material from its inception in 1876 until the closing years of the millennium preceding 1999. Several phases of growth are presented: first, as a one-man enterprise, Professor Paul Daniel Hahn introduced the teaching of Chemistry and fostered both pure and applied research; this developed with the founding of the University of Cape Town at the end of World War 1. A move into the new building at Groote Schuur followed, with a rapid expansion on many fronts after World War II. Apart from a brief interlude as a School comprising four separate Departments (1974)(1975)(1976)(1977)(1978)(1979)(1980)(1981)(1982)(1983)(1984)(1985)(1986)(1987)(1988), the Department of Chemistry continued to grow in terms of student numbers, courses offered, and productivity of its research groups, until the present time. The Department has occupied a large building, named after its first full-time professor, since 1972. Advances in performance, consequent on improved, computerised instrumentation and teaching techniques, are evident.

“…The strong interaction between amines and molten metal stearate phases and the possi-bilities for studying complex stabilities by this method were discussed by Barber and coworkers (9). Ammonia was found irreversibly absorbed on silver salt solutions until enough ammonia was introduced to form a stable ammine after which ammonia peaks showed a plateau suggesting formations of a second, unstable ammine (66). Solid silver nitrate has been used to react selectively with sec-bromide in a short precolumn, permitting a differential analysis of secand isobutyl bromides (98).…”
