British physicist Arthur Eddington (1882-1944) proved Einstein's prediction correct in 1919, when he observed and recorded the shifted positions of stars whose light passed by the Sun during a total solar eclipse. Concerns were quickly raised, however, about the accuracy of Eddington's photographic plates. Therefore, the physics and astronomy community deemed the reconfirmation of his findings necessary. In September 1922, many national and international teams spread out across Australia to photograph a total solar eclipse that passed over the entire width of the country. The best remembered effort was that of William Wallace Campbell, the Director of California's famed Lick Observatory, who set up camp at Warral, Western Australia. However, many other groups set up their equipment across the path of the eclipse, including at Cordillo Downs in the northeast corner of the State of South Australia. Led by George Dodwell, the Government Astronomer for South Australia for much of the first half of the 20th century, the Cordillo Downs expedition also confirmed Einstein’s theory and Eddington’s observation. In 1927, Carl Laubman and Harold Pank, prominent South Australians and the owners of the well-known optical firm Laubman &amp; Pank, went on a 12-month world tour as official representatives of the South Australian Government where they were to “enquire into and report upon the tests for visual acuity of drivers of public utility vehicles, ophthalmic standards, and lighting of industrial buildings in Great Britain, Europe and the United States.” During their tour – which included Palestine, Egypt, and Turkey in addition to Europe and North America – Laubman and Pank met with Einstein in Berlin where they provided him with the data from the Cordillo Downs expedition that confirmed his theory of general relativity.&nbsp; In the years leading up to Laubman and Pank's visit, Einstein had taken numerous journeys around the world: to the United States in 1921, Asia and the Near East in 1922, and South America in 1925. Perhaps inspired by Laubman and Pank's more recent experiences in Palestine (where Einstein was lauded only a few years prior), Einstein gave Laubman this "inspiration," in German, as a parting gift: "Traveling gives you a clear view into the unique characteristics of your familiar surroundings."

Two letters by <a href="https://www.sothebys.com/en/search?query=Albert+Einstein&amp;pfilters.dateRange=upcoming" rel="noopener noreferrer" target="_blank">Albert Einstein</a>, one <a href="https://www.sothebys.com/en/buy/luxury/books-&amp;-manuscripts/book?locale=en&amp;Book%20Type=Signed%2520and%2520Inscribed" rel="noopener noreferrer" target="_blank">hand-signed</a>.<ul><li>Sold as a set of 3: 2 letters, 1 envelope.</li><li>Albert Einstein (German).</li><li>Potsdam, Germany: 1931.</li><li>One of the letters is hand-signed by Einstein.</li></ul> The first letter is a single-paged autograph letter signed by Albert Einstein with one horizontal fold and one vertical fold. Letter accompanied by mailing envelope, both with matching paper-clip rust stain. Letter with some light wear along edges, small staining to lower corner. Addressed to G. W. Meyer and dated 8 Oktober 31 in Potsdam, the Letter reads in full: "Sehr geehrter Herr! Indem ich Ihnen für die Uebersendung des Buches von Henry George bestens danke, sende ich Ihnen anliegend die gewünschte Meinungsäusserung mit der Bitte um Weiterleitung an Mrs. Evans. Mit ausgezeichneter Hochachtung" and signed in ink "A. Einstein". He thanks Meyer for serving as an intermediary in getting a book to him and for forwarding the enclosed letter. The second letter is a typed copy of Einstein's previously enclosed letter, presumably made by Meyer before he passed the original on to Evans. Addressed to R. W. Evans and dated 8.10.1931 in Potsdam, the letter discusses Henry George's economic theory of poverty and land nationalization, compares it to Franz Oppenheimer's work, and proposes questions to be asked. Presumably he was sent a copy of Henry George's Progress and Poverty. First published in 1879, it sparked the Progressive Era, discussing the paradox of increasing inequality and poverty amid economic and technological progress as well as the economic value of land.
