Paul and Prosper Henry

 

The Henrys discovered NGC 1432, the Maia Nebula (Pleiades) in Taurus and the IC 434, Horsehead Nebula in Orion (a year earlier then Fleming). NGC 1432 was first seen on a plate taken on November 16, 1885 with the 13" (f/10) photographic refractor at Paris Observatory (see below); see also On Photographs of a new Nebula in the Pleiades, MNRAS 46, 98 (1886). The nearby Merope Nebula (NGC 1435) was dicovered visually by Tempel on October 19, 1859 with a 4" refractor at Venice.
