Walter Henry Jollyman, British bacteriologist, worked under Walter C.C. Pakes* in England during 1900 to 1903. In 1901 they published three papers in the Journal of the Chemical Society, Transactions, onthe bacterial decomposition of formic acid, the bacterial oxidation of formates by nitrates, and the collection and examination of the gases produced by bacteria from certain media. Two years later Jollyman contributed articles on "Apparatus for making anaerobic cultivations in fluid media" and "Recent advances in the bacteriological examination of water" to The Analyst (1903). He was a Fellow of both the Chemical Society (FCS) and the Institute of Chemistry (FIC).
In August 1903 Jollyman was appointed assistant analyst and bacteriologist in the Government Laboratory, Johannesburg, under Pakes, who was by then analyst and bacteriologist of the Transvaal Colony. He assumed duty in September. In March 1904, when plague broke out in Johannesburg and Pakes had to serve as medical officer of health to the Rand Plague Committee, Jollyman was temporarily put in charge of the laboratory.
By 1904 Jollyman was a member of the South African Association for the Advancement of Science and during that year served as a member of its publication committee and as joint secretary of Section B (which included bacteriology). At the association's annual congress, held in Johannesburg that year, he read a paper on "The science of bacteriology and its commercial value". With reference to the recent outbreak of plague he pointed out that the disease could be diagnosed bacteriologically at an early stage, and also dealt with the uses of bacteriology outside medicine. The paper was published in the association's Report for 1904 (pp. 242-251). He was still listed as a member, living in Johannesburg, in 1906. In 1903 he also joined the Chemical, Metallurgical and Mining Society of South Africa. Soon thereafter his "Notes on the persistence of cyanide in the stomach after death" was published in the society's Journal (1904/5, Vol. 5).
Jollyman did not adapt well to conditions in the Government Laboratory. As early as September 1904 he complained of his treatment by Dr Pakes and much correspondence about their differences followed. A committee appointed to enquire into Jollyman's conduct reported in April 1905. Pakes resigned his post that year and Jollyman was dismissed in 1906. However, he was again appointed in the civil service of the Transvaal Colony by the Colonial Secretary in 1907. His problematic conduct appears to have continued, for he was again dismissed in 1911. He asked for reconsideration of his dismissal, but the administration of the Transvaal Colony replied that it could not recommend his employment in the public service of the Union of South Africa.
After leaving South Africa Jollyman settled at Fort Jameson (now Chipata), Northern Rhodesia (now Zambia), where he farmed with tobacco for many years. He then settled in Nyassaland (now Malawi) where, on behalf of the government, he investigated the destruction of crocodiles by poisoning. From about 1951 he resided near Salima, where he conducted research on the tides and related movements in the level of Lake Nyasa. The results of this investigation were published in The Nyasaland Journal in 1955.
