Nomenclatress of the planet Pluto.
At the age of eleven years British schoolgirl Venetia Burney suggested the name Pluto for the newly discovered planet to her grandfather, Falconer Madan, astronomer and librarian at the time. He was reading aloud from the newspaper of the discovery at breakfast in their Oxford, England home. It was March 14th, 1930, and the news had just reached England this morning.
Curiously, her grandfathers brother Henry Madan is credited for giving name to Phobos and Deimos, the satellites of Mars. Venetias suggestion was referred to by The London Times as 'perhaps the happiest of all essays in classical nomenclature'. And indeed it might be.
