Joseph Jean Pierre Laurent

from Wikipedia, the free encyclopedia

Joseph Jean Pierre Laurent († 1900 ; also A. Laurent , while the first name was forgotten) was a French astronomer and chemist.


Laurent discovered the asteroid (51) Nemausa on January 22, 1858 . He did not make any further asteroid discoveries, little is known about himself. The astronomer Benjamin Valz , director of the Marseille observatory , described Laurent as “élève distingué de l'école marseillaise” (“excellent pupil of the Marseille school”), from whose successor Édouard Stephan called “jeune homme très habile” (“very able young man ”). As his official activity "contrôleur au bureau de garantie" ("inspector in the guarantee office") is called, accordingly astronomers described him as "amateur" or "astronomical dilettante".

Nemausa was discovered at a private observatory in Nîmes that belonged to a house that Benjamin Valz previously lived in. Valz became director of the Marseille observatory and entrusted the house to Laurent. The house at 32 Rue Nationale now bears a plaque commemorating the discovery.

For his discovery, Laurent was awarded the Prix ​​d'Astronomie Medal of the Lalande Foundation in 1858 together with other discoverers of asteroids and comets ( Goldschmidt , Searle , Tuttle , Winnecke and Donati ) .

In honor of Laurent, an asteroid (162) discovered in 1876 by Prosper Mathieu Henry was named Laurentia .
