Evidence of light bending due to gravitational effects is an important milestone in the history of science because measurements of light deflection in astronomical observations during the 1919 eclipse confirmed the value predicted by Einstein's theory of general relativity in 1915. This had an extraordinary repercussion in the press, which led Einstein to worldwide recognition and to becoming the most famous scientist in the non-scientific media of the twentieth century. However, light deflection had been a matter of attention since Newton. This paper discusses the advances and calculations performed by Einstein's predecessors and details his trajectory in the development of relativity theory until the exact determination of the gravitational deflection of light. [ABSTRACT FROM AUTHOR]

The article describes the circumstances in which the first attempt was made to confirm one of the predictions of Einstein's theory, linked to the deviation of light by gravity, made at the eclipse occurred in 1912, by the expedition of the Observatorio Nacional Argentino that was installed in the town of Cristina (Brazil). The observations were planned at the request of Erwin Finlay-Freundlich, an astronomer who since 1911 helped with verifications of the ideas of the eminent German physicist. The relationships that occurred between the director of the Argentine institution, Charles D. Perrine and Freundlich, and with the director of the Observatório do Rio de Janeiro, Henrique C. Morize are detailed. In addition to these little-known events, the expeditions of 1914 and 1916 are described, as well as the reasons why the ONA was not present at the famous eclipse of 1919.
