At Munich, Johann Soldner calculated the deflection, due to gravity, of starlight as it grazes the Sun’s limb (1801). Thus he is sometimes said to have presaged  Albert Einstein; however, because he used Newtonian gravity and a particle theory of light, Soldner’s deflection is half of Einstein’s 1916 value.
