I sent a message through Nabble to the address at anest.ufl.edu, which was
returned "The e-mail address you entered couldn't be found. Please check the

You're not the first one looking for him. In the Dolphin Smalltalk
newsgroup they were looking for him too a year ago or so. I don't know
if they ever found him.

Good luck. He is a valuable Smalltalker.

I used to enjoy Bill's perspective on things coming to Pharo from Dolphin. It would seem there is unfortunate news.

Wilhelm "Bill" K. Schwab Ph.D., 48, of Gainesville, Florida, died Friday September 7, 2012 at a friend's home, after a determined battle with cancer.
[...] His software was far more reliable than the commercial operating systems on which it ran. He even wrote his own "object request broker," a specialized networking software tool, using Smalltalk, an exotic computer language. With his tool, he created, implemented and maintained a fully functional handwriting-capable anesthesia medical record system that was well ahead of its time, and was used for years in actual patient care in multiple operating rooms. His software never required "downtime."
