An anemometer measures wind speed and direction, and helps meteorologists determine weather conditions and patterns. This instrument belonged to George Templeman Kingston, director of the Toronto Magnetic and Meteorological Observatory between 1855 and 1880. In 1871, the observatory, located on the grounds of the University of Toronto, became the headquarters of the Meteorological Service of Canada. From this base, Kingston oversaw the creation of a national network of weather-observation stations. This anemometer was in service between 1876 and 1900, and its windmill-vane design was considered a major advance in wind measurement.
The word anemometer is from the Greek word for wind, anemos.
