Description
George Washington Hough (1836-1909) was an astronomer who served as director of the Dudley Observatory in Albany, New York, from 1862 to 1874, and as director of the Dearborn Observatory in Chicago from 1879 until his death.
While at the Dudley Observatory, Hough devised a recording thermometer, a recording barometer, and an anemograph. This example of his recording thermometer contains six iron rods and five brass rods, and their differential expansion controls a marking pen. The instrument is not dated, but inside it is a piece of paper from the New York Times of March 12, 1860.
