He did his Ph.D. dissertation in 1913 at the Landessternwarte Heidelberg-Königstuhl (Königstuhl Observatory, near Heidelberg) at the University of Heidelberg [1].
At the time, the observatory at Heidelberg was a center for asteroid discovery under the direction of Max Wolf, and during his time there Helffrich discovered a number of asteroids.
