 Johann Georg von Soldner

Johann Georg von Soldner (1776–1833) was a German physicist and mathematician, known primarily for his contributions to astronomy and the study of gravitational theory. He is best recognized for his work on the gravitational constant and for his advancements in the mathematical formulation of gravitational phenomena. Soldner is notable for his investigation into the deflection of light by gravity, which anticipated some of the concepts later developed in the context of general relativity by Albert Einstein.
