Designed by Leon Battista Alberti somewhere in mid 15th century the Anemometer was a simple instrument made to measure wind speed. It had a rectangular metal plate attached to a horizontal axis with a hinge, so that in the wind metal plate lifted, giving an indication of relative wind speed that could be measured crudely on a curved scale bar below the plate.
The Anemometer designed by Leon Battista Alberti was used for around 200 years, until a British scientist, Robert Hooke reinvented it in 1664, placing the moving plate beneath the curved scale bar to ensure more accurate measurements.
