Haas began his UT career in 1963. For thirty-five years, he taught courses including western civilization, Austrian and German history, and multiple graduate level seminars.
Haas passed on to students and friends his interest in old items such as Tennessee marble with 400 million-year-old fossils, samples of which are found in the construction of his home. For many years he was a member—and for one year president—of the East Tennessee branch of the Archaeological Institute of America.
Haas’s extensive collection of Roman artifacts and coins is now at the McClung Museum of Natural History and Culture. Students working on projects can touch these more than two thousand year-old items.
Haas is survived by Roswitha Haas, his wife of fifty-three years; brother George Haas; nieces and nephew Theresa Krause, Patricia Cleveland, Susan Meyer, and Christopher Haas and their families.
The family held a private burial for Haas. Donations may be made in his memory to the McClung Museum or to the Department of History Enrichment Fund.
