The Richard Frères house was founded in Paris by Félix Richard in 1845, the year in which the company also produced the first metal barometer. In 1871 the company was taken over by Jules Richard and for over 160 years it has produced and designed environmental control and monitoring equipment for various parameters, such as temperature, humidity, pressure etc.
The anemometer or air flow meter is an instrument used to detect and measure the speed of an air mass. The wind speed is calculated based on the number of revolutions made in a time determined by a pivoted wheel equipped with vanes that activate a counter: from the number of revolutions per unit of time it is possible to calculate the wind speed. The first type of anemometer was described by Leon Battista Alberti in 1450 and later taken up by Leonardo da Vinci. Anemometers equipped with moving propellers probably derive from windmills; this idea, for example, was exploited by Robert Hooke starting around 1670, one of the greatest scientists of the seventeenth century and one of the key figures of the scientific revolution. In November 1662 he took a job at the Royal Society as curator of experiments, a new professional figure created for him, which made Hooke the first scientist paid solely for the purpose of carrying out research.
