Victor Puiseux

Victor Alexandre Puiseux (French: [pɥizø]; 16 April 1820 – 9 September 1883) was a French mathematician and astronomer. Puiseux series are named after him, as is in part the Bertrand–Diquet–Puiseux theorem. He was also an accomplished amateur mountaineer. A peak in the French alps, which he climbed in 1848, is named after him.

A species of Israeli gecko, Ptyodactylus puiseuxi, is named in his honor.

He was born in 1820 in Argenteuil, Val-d'Oise. He occupied the chair of celestial mechanics at the Sorbonne. Excelling in mathematical analysis, he introduced new methods in his account of algebraic functions, and by his contributions to celestial mechanics advanced knowledge in that direction. In 1871, he was unanimously elected to the French Academy.

One of his sons, Pierre Henri Puiseux, was a famous astronomer.

He died in 1883 in Frontenay, France.
