Discovered 1923 Aug. 9 by K. Reinmuth at Heidelberg.

Named in honor of the astronomer and mathematician Franz Xaver Freiherr von Zach (1754–1832). He was the director of the Seeberg Observatory near Gotha, Germany. Von Zach recovered planet(1) Ceres profiting the Gauss computings because the planet was lost in consequence of Piazzi’s serious illness. He founded the journalMonatliche Correspondenz zur Beförderung der Erd- und Himmelskunde which was the main medium for exchange and improvements in observation and data treatment of the first asteroids.

Zach is also honored by a lunar crater.
