Swedish astronomer, physicist, and mathematician (1701–1744). Rare ALS in Swedish, signed “And. Celsius,” one page, 8 x 5.75, May 20, 1731. An untranslated letter of recommendation for student Dan Petraeus. In fine condition, with mild overall wrinkling and a stain to the right edge. This letter was written by Celsius early in his career, during his second year as professor of astronomy at Uppsala University. In 1730 he had published A New Method for Determining the Distance from the Earth to the Sun, and throughout the early 1730s he traveled through Germany, Italy, and France, visiting most of the major European observatories. He went on to play a major role in raising public and private funding to build a modern observatory in Sweden, and was able to found the Uppsala Astronomical Observatory in 1741.
