- Named for Thomas Gwyn Empy Elger (October 27, 1836 – January 9, 1897), a lunar mapper and the first director of the Lunar Section of the British Astronomical Association (BAA). He is best known as a careful and indefatigable selenographer. He is most remembered for his book The Moon: A full Description and Map of its Principal Physical Features. Published in 1895, its maps are still highly regarded by lunar observers due to their uncluttered nature.
- An account of the recovery of Elger's nearly-lost observing books appears starting on page 46 of the January 1956 issue of JBAA.
