11433 Gemmafrisius           Discovered 1977 Oct. 16 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Gemma Frisius (Gemma Phrysius, Gemma Reyneri, 1508-1555) born in Dokkum, Friesland, studied in Leuwen, Belgium, as a geographer, scientist and physician. He devised new globes, described how an accurate clock could be used to determine longitude and improved the astrolabe. Mercator was one of his students.
