F.H. Mitchell (or Michell), associate member of the (British) Institution of Electrical Engineers, was a lecturer in electrotechnics under Professor J.H. Dobson* at the South African School of Mines and Technology, Johannesburg (later the University of the Witwatersrand) from about 1910 to 1914. During that time he published the following papers: 'The measurement of large alternating current e.m.f.'s and power by the Kelvin balance' (1910), and 'Short discourse to students' (1915) in the Transactions of the South African Institute of Electrical Engineers; and 'Phenomena connected with the application of continuous currents to the stator or rotor of a 3-phase induction motor' (Transactions of the South African Institution of Engineers, 1913).
He is probably the same person as F.H. Michell, the author of 'Notes on modern electrical machinery' (Transactions of the South African Institute of Electrical Engineers, 1911/2); possibly also the same person as F.H. Michell, assistant engineer stationed at Pretoria, who was called upon to retire from the public service in 1918.
