George Arthur Webb was an associate of the (British) Institution of Electrical Engineers. Though he was a British subject, he resided in Randfontein, Gauteng, in September 1908 when he applied for a United States patent (granted in 1910) for a 'Jockey or rope-grip for mechanical haulage'. Shortly thereafter he contributed a paper on 'The earthing of electrical apparatus' to the Transactions of the South African Institute of Electrical Engineers (1909/10, Vol. 1(6), pp. 141-147).
Webb became a member of the South African Association for the Advancement of Science in 1914 and was still a member by 1918, when he lived in Johannesburg.
