Arthur L. Flagg was a practicing Arizona mining engineer, an accomplished author, and an Arizona mineral locality aficionado. Above all else, he was an enthusiastic unbridled “rockhound” who undauntedly promoted the earth sciences to the young and old alike. Through his personal passion and involvement in forming several important mineral-based societies, Flagg inspired generations of future collectors and earth scientists. In 1962, a year after his death, family, friends, and society members created a suitable memorial: The A. L. Flagg Foundation for the Advancement of Earth Sciences, a nonprofit educational and scientific tax-exempt corporation, now known as the Flagg Mineral Foundation.
Philip D. Richardson, a structural engineer by profession, has worked as a geological field technician and is the Flagg Mineral Foundation vice-chairman. A field collector of Utah and Arizona minerals, he has previously written for Rocks & Minerals.
