query: When was the Whyte notation introduced?
passage: Whyte notation
The Whyte notation for classifying steam locomotives by wheel arrangement was devised by Frederick Methvan Whyte,[2] and came into use in the early twentieth century following a December 1900 editorial in American Engineer and Railroad Journal. The notation counts the number of leading wheels, then the number of driving wheels, and finally the number of trailing wheels, groups of numbers being separated by dashes.[3] Other classification schemes, like UIC classification and the French, Turkish and Swiss systems for steam locomotives, count axles rather than wheels.
passage: John Whyte (politician)
He was born in Dunfermline, the son of John Whyte and Elspeth Simpson. Whyte was educated in Fife and came to Canada East in 1858. In 1859, he married Harriet Donaldson Johnson. He worked at the Harvey Hill mine until 1862 and then was foreman at the mine in Sutton. He became a merchant at Leeds (later Saint-Pierre-de-Broughton) in 1865. He was elected to the Quebec assembly in an 1884 by-election held after George Irvine was named a judge. Whyte was defeated when he ran for reelection in 1886 and 1892. He died in Leeds at the age of 88.
