Herbert Bristol Dwight

Herbert Bristol Dwight (8 September 1885, Geneva, Illinois – 30 June 1975) was an American-Canadian electrical engineer.^[1]

Dwight was educated in elementary and secondary schools in Ontario, attended Toronto University for two years, and then attended McGill University, graduating there in 1909 with a B.Sc. in electrical engineering. He developed a method for calculating the skin effect resistance ratio of a tubular conductor^[1][2] and derived formulas for mutual inductance of coils with parallel axes, repulsion of coils with parallel axes, and self-inductance of long cylindrical coils.^[3]

He was an Invited Speaker at the ICM in Toronto in 1924.
