Carl Gustav Witt (29 October 1866 – 3 January 1946) was a German astronomer and discoverer of two asteroids who worked at the Berlin Urania Observatory, a popular observatory of the Urania astronomical association of Berlin.

[2] He wrote a doctoral thesis under the direction of Julius Bauschinger.

Witt discovered two asteroids, most notably 433 Eros, the first asteroid with a male name, and the first known near-Earth object.

[3][4] His first minor planet discovery was the main-belt asteroid 422 Berolina, that bears the Latin name of his adoptive city.

[5] The minor planet 2732 Witt – an A-type asteroid from the main-belt, discovered by Max Wolf at Heidelberg Observatory in 1926 – was named in his memory by American astronomer and MPC's longtime director, Brian G.
