Johann Gabriele Doppelmayr was a German mathematician, astronomer, and cartographer. He was born in Nüremberg as the son of a merchant but became something of a polymath by studying at a range of universities throughout Europe. He was widely recognized as an authority during his lifetime, achieving notable positions in the Berlin Academy, The Royal Society, and the Imperial Academy of Sciences and Letters in St. Petersburg.

Throughout most of his professional life, Doppelmayr had a close working relationship with the famous Dominican friar and cartographer Johann Baptist Homann, who among other things published one of his most famous books, the Atlas Coelestis (1742).
