Mercury's Perihelion From Le Verrier To Einstein, by N. T. Roseveare, is available from the Internet Archive. Based on his doctoral thesis, this 1982 book provides a thorough analysis of the many proposals that had been set forth to explain Mercury's anomalous precession. There are two very serious issues with Gerber's prediction. 1) It did not take into account the variation of mass with velocity. At around the turn of the century, there were several competing theories seeking to explain this EMPIRICALLY OBSERVED phenomenon first noted by Thomson in 1893 and carefully characterized in subsequent experiments by Kaufmann, by Bucherer, Hubka, Neumann, Guye etc. https://tinyurl.com/4munb3ua The variation of mass with velocity adds an additional 7" advance in the perihelion of Mercury, so that Gerber's theory would predict an incorrect overall anomalous advance of 49". 2) Gerber's gravitation theory provides an incorrect prediction for the gravitational deflection of light by the Sun, 3/2 the value given by general relativity. Now, in the years subsequent to the Eddington expedition, various other eclipse measurements gave rather widely variant results, some of which would have favored Gerber. However, present-day measurements using methods of far greater precision have consistently validated the GR prediction.
