My life before Princeton included

• teaching Computer Science (Programming, Data Structures, Programming Languages, Operating Systems) at Boston University. I also supervised the Visual Languages Programming Group. At that time, I was the only regular, full-time CS faculty member without a doctorate, so I endured more than the usual spattering of committee assignments and meetings.

• teaching summer and evening courses for Harvard University (Computer Science, Calculus, and Linear Algebra),

• consulting for ETS (the College Board and GRE people),

• technical writing and quality control engineering for Unitrode, a Massachusetts-based integrated circuit manufacturer,

• snagging a couple of Graduate degrees (Tufts, Harvard, Princeton), and

• living and working overseas.
