Disclaimer: This is not an invitation to an argument. Just passing on some lore.
In the 70's there was a very popular professor at UT, Dr. Bass. Students loved him because he was had an amazing wit, was prone to profanity in class to make
his points, and if you didn't make a B or better in his class you had no business in college. Don't remember how this came up but Dr. Bass explained to us one day
that the school nickname wasn't formally adopted by UT until the Spanish-American War broke out and every ROTC member left school to volunteer for the war.
Now is true, I dont know. I know about all the references to The Volunteer State going back to 1812, the question is when was Volunteers assigned to UT sports?
