323 Brucia was the first asteroid to be discovered by the use of astrophotography. It was also the first of over 200 asteroids discovered by Max Wolf, a pioneer in that method of finding astronomical objects. Discovered in 1891, it was named in honour of Catherine Wolfe Bruce, a noted patroness of the science of astronomy.
It it also a Mars-crosser asteroid.
