Darton, Nelson Horatio (17 December 1865–28 February 1948), geological mapper, groundwater specialist, and bibliographer, was born in Brooklyn, New York, the son of William Darton, Jr., a shipbuilder and civil engineer, and Caroline Matilda Thayer. Darton was a self-trained geologist who dropped out of public school before the age of thirteen to apprentice as a chemist in his uncle’s business. He became a member of the American Chemical Society at age sixteen and shortly thereafter started his own business, selling distilled water. As a practical chemist he became interested in minerals and collected in New Jersey. By age seventeen, Darton had spoken before the New York Academy of Sciences and published his first paper. The conclusion he derived from fieldwork was that some of the rock strata in eastern New Jersey were ancient lava flows, a new concept at that time, but one that was immediately accepted....
