^Yes! I had an architecture professor who was “just” an adjunct. https://legacy.lib.utexas.edu/taro/utaaa/00009/aaa-00009.html He was in charge of a lot of renovations at Colonial Williamsburg, along with work in historical Galveston. He also happened to be a WWII pilot who was shot down and held in a German POW camp. One of the most amazing teachers I had at UT-Austin. Another one of my “just an adjunct” professors was a leading expert in masonry design. https://masonrysociety.org/clayford-t-grimm-recognized-honorary-member/ He was also in the infantry in WWII and fought in the Battle of the Bulge. Both men shared lots of stories from their time in the service.
I’m sure glad I didn’t reject UT because of their adjuncts.
