Heinrich Ludwig d'Arrest (July 13, 1822 - June 14, 1875)

Born in Berlin.

Worked in Copenhagen. Discovered 342 NGC objects, mainly with an 11-inch refractor.

D'Arrest was honored by naming a Moon Crater after him (2.3N, 14.7E, 30.0 km diameter, in 1935) as well as a crater on Mars' moon Phobos (35.0S, 185.0W). Asteroid (9133) d'Arrest was discovered on September 25, 1960 by C. J. van Houten, I. van Houten-Groeneveld and T. Gehrels at Palomar Observatory and provisionally named 3107 P-L; independent findings have provisional designations 1990 UJ3 and 1990 VN9.
