Alfred Ewing
British physicist and engineer (1855-1935)
Sir James Alfred Ewing MInstitCE (27 March 1855 − 7 January 1935) was a Scottish physicist and engineer, best known for his work on the magnetic properties of metals and, in particular, for his discovery of, and coinage of the word, hysteresis.
It was said of Ewing that he was 'Careful at all times of his appearance, his suits were mostly grey, added to which he generally wore – whatever the fashion – a white piqué stripe to his waistcoat, a mauve shirt, a white butterfly collar and a dark blue bow tie with white spots.' He was regarded as brilliant and successful, but was conscious of his dignity and position. On appointment to head the newly created Admiralty codebreaking department, the Director of Naval Intelligence, Henry Oliver, described him as 'too distinguished a man to be placed officially under the orders of the Director of Intelligence or Chief of Staff'. His first wife, Annie, was an American, a great great niece of George Washington.
Life

Born in Dundee, Scotland, Ewing was the third son of the Reverend James Ewing a minister of the Free Church of Scotland. He was educated at West End Academy and the High School of Dundee, Ewing showed an early interest in science and technology.
In a family whose chief interests were clerical and literary, I took my pleasure in machines and experiments. My scanty pocket money was spent on tools and chemicals. The domestic attic was put at my disposal. It became the scene of hair-raising explosions.

Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
