Johann Gabriel Doppelmayer (27 September 1677 – 1 December 1750) was a German mathematician, astronomer, and cartographer. He published several works of a scientific nature, covering topics on mathematics and astronomy, including sundials, spherical trigonometry, and celestial maps and globes. One of his works also included useful biographical information on several hundred mathematicians and instrument makers of Nuremberg.
Doppelmayr developed a close relationship with the Dominican monk and cartographer Johann Batist Homann, the founder of a famous cartographic publishing firm. In the early 1700s, Doppelmayr prepared a number of astronomical plates that had appeared in Homann’s atlases, which in 1742 were collected and issued as the Atlas Coelestis in quo Mundus Spectabilis… The atlas contained 30 plates, 20 of which treated astronomical themes and historical development, including Copernicus’s and Tycho Brahe’s cosmological systems, illustration of planetary motion and the solar system, and a detail of the moon’s surface based on telescopic advances.The remaining ten plates were actual star charts, including hemispheres centered on the equatorial poles.
