139028 Haynald           Discovered 2001 Feb. 28 by K. Sárneczky and A. Derekas at Piszkéstető.
Lajos Haynald (1816-1891), a Hungarian cardinal and Archbishop of Kalocsa-Bács, was also a botanist and a generous patron of Hungarian science. He had the astronomical observatory built in Kalocsa, where Gyula Fényi made observations of sunspots for four decades.
