On the UT campus and looking for a fascinating piece of scientific history? Check out the newly-installed display of the X-ray machine pictured here. This isn't any old X-ray machine. It's over 100 years old, and was part of the ground-breaking research done by Nobel Laureate Hermann Joseph Muller. He was a geneticist and UT professor best known for founding the field of radiation genetics. Much of the research that led to his 1946 Nobel Prize in Physiology or Medicine was conducted at UT Austin in the 1920s using fruit flies and this very X-ray machine! The display is in the lobby of the PAT building.
