A. D. Stenger. 
Arthur Dallas Stenger better known as A.D. Stenger is perhaps one of Austin's better known residential architects, an impressive feat for someone that dropped out of UT prior to graduating.  A.D. Stenger was not one to follow the traditional path however.  He was innovative, had strong opinions and wasn't afraid to do things his own way.  In 1950 he passed his architectural exams just prior to graduating the University of Texas School of Architecture. The demand for post war housing was high, and he was ready to work.
