Named after André Kertész - Hungarian-born American photographer (1894-1985).
Located in the western edge of Mercury's giant Caloris basin, Kertész crater has some unusual, bright material located on its floor. Sander crater, located in the northwestern edge of Caloris basin, also shows bright material on its floor. Just northeast a small crater has very bright rays and ejecta, indicating that the crater is young. (wikipedia entry)
A crater is a circular depression likely created by an impact event. On Mercury they are named after deceased artists, musicians, painters, and authors who have made outstanding or fundamental contributions to their field and have been recognized as art historically significant figures for more than 50 years.
