95824 Elger           Discovered 2003 Mar. 28 by the Catalina Sky Survey.
Thomas Gwyn Empy Elger (1836-1897) was a British selenographer who was the first Director of the Lunar Section of the British Astronomical Association. His book The Moon (1895) is considered a classic lunar observing guide for the amateur astronomers of that time.
