Die (Wieder-)Entdeckung von Eulers Mondtafeln

摘要

Up to now only three lunar tables by Leonhard Euler (1707–1783), published in 1745, 1746, and 1772, were known. For a long time, however, it was assumed that the first two of these tables were identical. The author compared these tables with each other and proved the contrary. This fact also transpires from an examination of their history, which was reconstructed using Euler’s correspondence. In addition, evidence has been found in Euler’s voluminous scientific correspondence and in contemporary publications of the eighteenth century that, between 1742 and 1750, Euler published additional lunar tables anonymously. The author proved Euler’s authorship of at least five lunar tables containing some 100 pages, which were neither recorded in the list of his works nor published in the Leonhardi Euleri Opera Omnia.
