Hippolyte Pixii

Antoine- Hippolyte Pixii (* 1808, † 1835) was an instrument maker in Paris.

His father was the instrument maker Nicolas Constant Pixii ( - Dumotiez ) ( 1776-1861 ).

Hippolyte Pixii learned his father's profession and built in the 1820s instruments for André- Marie Ampère and Claude Servais Mathias Pouillet.

1831 Michael Faraday had presented his magneto-electric machine, a circling between the poles of a horseshoe magnet copper disc from which he took with sliding contacts DC.

1832 built Pixii the first AC generator based on the detected Faraday principle of magnetic induction. Pixiis unit containing a winch driven by a rotating magnet, the moving of a coil with an iron core passed. He was able to create sparks of several millimeters in length. Jean Nicolas Pierre Hachette reported on 3 September, the Academy of Sciences of what the Academy Pixii on November 19, awarded the third prize.

Since AC was unsuitable for galvanic experiments, Pixii built in 1833 with a proposed Ampère rocker as an inverter ( commutator ) the first generator for pulsating direct current.

His studio existed until 1860.
