Ah this is sad news. I came to know of him by way of UIUC's Engineering Open House. Back in 03' or 04' a rag tag group of us put together an "asymmetric capacitor" exhibit -- a sort of simple ion thruster. A kind hearted TA put our project in for an award Bitzer had sponsored, and it went in our favor.
It was not a large amount after dividing it up, but it was so rare in the college days to have any spare change for anything, and it sure meant a lot at the time. https://ece.illinois.edu/academics/ugrad/scholarships-and-aw...
