Life with Unix says: The W in awk. Wrote 1comp.
A Research Unix Reader says: Peter J. Weinberger has moved effortlessly among number theory, databases, languages, and networking. Weinberger boasts the middle initial of awk, the 10 library for pi ', and a famous visage (see FACED, page 14). In v8 and v9 appeared an unbounded precision arithmetic package mp, a fast factoring program qfactor, a B-tree library cbt, and a new code generator for C, all Peter's work. Above all, his network file system bound a stable of machines together into a logically homogeneous system (v8).
