Wilson W. Crook III:An Inventory of Papers at the Texas State Archives, [ca. 1977]
Biographical SketchWilson W. Crook III is a native Texan, graduating with a degree in geology (mineralogy) from Southern Methodist University. While working on his honor's thesis, he collected and studied rare-earth minerals from the Clear Creek pegmatite, located in Burnet County, Texas. After finishing his studies at Southern Methodist University, he entered the graduate school of mineralogy at the University of Michigan at Ann Arbor, Michigan. He continued his studies in the area of pegmatite by researching rare-earth minerals in the Central Mineral Region in and around Llano and Burnet counties, also referred to as the Barringer-Hill rare-earth pegmatite district. In 1975, while looking through specimens gathered while at Southern Methodist University, he discovered a new rare-earth element. Crystals of the mineral are small (0.1mm), translucent, and apple-green in color. He named the mineral texasite, after his native state of Texas.
