Johnson Hall houses the Quaternary Research Center and the Department of Geological Sciences. Quaternary research focuses on the processes that are now shaping the natural environment and on the geologic record of environmental changes during the Quaternary Period - roughly the last two million years.
Built in 1930, it is named for Orson B. Johnson, who joined the faculty in 1882 - as a professor of physiology, botany, zoology, biology, mineralogy, geology, chemistry, and natural philosophy! He had graduated from law school and was admitted to the bar, but he declared that "law doesn't suit my temperament" and turned to the sciences. Because of his extensive insect collection and his intense preoccupation with the creatures, his students affectionately nicknamed him "Bug."
