Arthur Lewis Hall

Arthur Lewis Hall FRS (10 January 1872 – 13 August 1955) was a British geologist, who worked in South Africa for most of his career. He was awarded the Murchison Medal of the Geological Society of London in 1930 for his work on the Bushveld Igneous Complex, and elected to the Royal Society in 1935.

Early life and education Hall was born in Birmingham, to William Hall and Mary Ann (née Smith). At an early age he moved to Germany. He went to school in Freiburg, Bonn, Schwehn, Westphalia and finally to the Real Gymnasium, Kassel. At the age of 19 he won a scholarship to study at University College, Bristol. In 1896, Hall went to Gonville and Caius College, Cambridge, and graduated with first class honours in geology in 1899. That summer he went to Wales to learn geological surveying with Philip Lake, a physical geographer who was later a lecturer in Cambridge. Hall then spent two terms in Cambridge as assistant demonstrator in mineralogy, working for the professor of mineralogy W J Lewis.

Career In 1900, Hall joined Dulwich College as a science teacher; a post he held for two years. This expedition drew attention to extraordinary nature of the Bushveld complex, and to the work that had already been done there by Molengraaf and Hall over the previous two decades. In 1932, Hall published his memoir on the Bushveld, which stretched to more than 550 pages. He was elected as a fellow in 1935.

After retirement from the geological survey at the age of 60, Hall continued to work as a consulting geologist. He also published a vast compendium of analyses of rocks, minerals, ores, coal, soils and waters from southern Africa, and updates to his series of monographs on the bibliography of South African geology, until his failing eyesight meant that he had to stop.

Awards Hall's work was widely recognised during his career. He was awarded the ScD degree from Cambridge University in 1925. He was the first recipient of the Draper Memorial Medal of the Geological Society of South Africa in 1932. Hall was awarded the Murchison Medal in 1930, and was elected to the Royal Society in 1935.

Personal life Outside his work, Hall was a proficient violinist, who regularly performed both chamber music and in orchestras. He was also a regular supporter of classical music concerts in Pretoria. According to his biographer Sidney H. Haughton, Hall 'wasted no time with the helpless amateur or the pretentious professional' in either geology, or music.

Hall married Rosalie Powell, from Clifton, Bristol, in August 1900. They had a daughter and three sons. Two of Hall's sons died before him.
