Charles Messier (French: [?a?l me.sje]; 26 June 1730 – 12 April 1817) was a French astronomer.
He published an astronomical catalogue consisting of 110 nebulae and faint star clusters, which came to be known as the Messier objects.
The purpose of the catalogue was to help astronomical observers, in particular comet hunters like himself, distinguish between permanent and transient visually diffuse objects in the sky.
