William L. Fisher is the Leonidas T. Barrow Centennial Chair in Mineral Resources and Professor Emeritus at The University of Texas at Austin, in the Department of Geological Sciences. He was the first dean of the Jackson School of Geosciences, which he was instrumental in establishing as well as in securing its substantial endowment.  He was the longest serving director of both the Geology Foundation and the Bureau of Economic Geology. At the Bureau his role as state geologist put him at the forefront of state resource management and national energy policy.

D. Hoye Eargle, George Pinkley, and Paul de Vergie led and co-authored the first field trip to the Karnes Uranium District for the South Texas Geological Society in 1958, nearly 50 years ago. Since then, various field trips have been held to this area by different groups. Additionally, there are a wealth of research and papers on the uranium geology of the area, mostly by the USGS, and the University of Texas/Bureau of Economic Geology. A few of the early geologists who worked there in the 1950s are still working and have some fascinating stories of those times.
