J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels. German mathematician, astronomer and cartographer Johann Gabriel Doppelmayr (1677-1750) worked in Nürnberg. His Atlas Coelestis, published in 1742, was one of the major celestial atlases of the eighteenth century.
