biography

De Hautefeuille was born in Orléans, the son of a baker. In his youth he came into contact with Maria Anna Mancini , Duchess of Bouillon, whom he accompanied on trips through Italy and England. Because of their aspirations, he became a priest of the Roman Catholic Church.

One of the most important inventions of de Hautefeuille was the replacement of the pendulum with a balance wheel as a clock for clocks . Around 1670 he had a correspondence with Christiaan Huygens in which de Hautefeuille proposed the spiral spring . While Robert Hooke also claimed the authorship of this discovery, Huygens was the first to build a watch with a balance wheel.

De Hautefeuille also carried out experiments in the field of acoustics , including examining the mouthpiece and writing an essay on the echo , which was awarded in 1718 by the Bordeaux Academy. He also designed improved optical lenses and proposed a method of moving water through the explosive power of black powder . He was also interested in the tides and invented the thalassameter , a device for measuring the tidal range .

In 1678, de Hautefeuille proposed an early form of the internal combustion engine using black powder, but did not carry out his ideas. However, in the same year he was the first to propose the use of a piston in a heat engine . Huygens then built such a prototype two years later .

He rarely carried out his inventions in order to be able to devote himself to something new. The Paris Academy of Sciences attested him the value and usefulness of several of his inventions, but never discussed his inclusion. On December 14, 1687, however, he was elected a member ( Fellow ) of the Royal Society .
