Mr. A. P. Trotter

BY the death on July 23 of Alexander Pelham Trotter, at the advanced age of ninety-one, science and engineering lose another great figure linked with researches which have become classic. In his early years Mr. Trotter was concerned with dynamo manufacture, afterwards becoming editor of The Electrician until 1896, when he accepted a position as Government electrical engineer at the Cape of Good Hope. On return to Britain three years later he became electrical adviser to the Board of Trade, which position he held until reaching the age of retirement in 1917.
