Bernhard Walther

Bernhard Walther (1430 in Memmingen – June 19, 1504 in Nuremberg) was a German merchant, humanist and astronomer based in Nuremberg, Germany.

The merchant was a man of large means, which he devoted to scientific pursuits. When Regiomontanus settled in Nuremberg in 1471, they worked in collaboration to build an observatory and a printing press. After the death of Regiomontanus in 1476 at Rome, Walther bought his instruments, after Hans von Dorn, commissioned by the Hungarian king, had tried in vain about it with the council of Nuremberg. Thenceforward, he continued the observation of planets till his death. His house, purchased in 1509 by Albrecht Dürer, is nowadays a museum.
