Colleagues,

This is a great loss. RIP.

I still refer to Lancaster's CMOS Cookbook and Active Filter Cookbook 
from time to time.

But his largest influence on my life was his PostScript hacking. His 
work in that realm helped lead to what I jokingly refer to as "my 
career" (Aldus, Visio, Adobe).

Thanks,

Olav Martin Kvern
