Ernst von Rebeur-Paschwitz (9 August 1861 – 1 October 1895) was a German astronomer, geophysicist and seismologist.

After traveling to England and Ireland, he continued studies in Berlin and Geneva, with a one-year break for military service.

[6] In 1883, he received his doctorate at the University of Berlin with a dissertation "On the Movement of Comets in Resisting Average" and became an assistant at the Observatory.

The pendulums designed to measure the horizontal motion of the ground due to supposed lunar tides.

[7] The realization that strong earthquakes can be recorded at great distances helped usher in the modern era in the field of seismology and the physics of the Earth’s interior.

[11] As a result, Englishman John Milne established network of stations with simply-to-use horizontal pendulums in the British colonies.

[1] In his last publication of the same year, Rebeur-Paschwitz also argued for establishing an internationally centralized bureau to collect global seismological observations.
