Historical Notes
1450 The first anemometer, a disc placed perpendicular to the wind, was invented by the Italian architect Leon Battista Alberti. Robert Hooke, an English physicist, later reinvented the anemometer.

1846 John Thomas Romney Robinson, an Irish physicist, invented the spinning-cup anemometer. In this device, cups are attached to a vertical shaft; when the cups spin in the wind, it causes a gear to turn.
