[Highland Park] Wolfgang Swoboda memories, relatives, etc.

I am looking for any information -- e.g., memories, knowledge of relatives, . . . -- on Wolfgang Swoboda. He completed a PhD at the University of Pittsburgh in 1974, and died not too long afterwards. I have heard that perhaps he has family in Pittsburgh. Today a visiting scholar very appreciative of his work asked me if I knew anything more about him, and I thought I would ask the Highland Park neighborhood for any clues. So, any information you might have would be much appreciated.
