Miller is also co-inventor of one the two variations of compression algorithm called LZW. Strangely, if perhaps not unusually, two groups separately invented and separately received patents on the algorithm, and in each case the third initial is W, but in one case Welch and in the other Wegman (the IBM one). IBM's LZW is implemented by terse (AMATERSE and friends), while the other is the base for UNIX compress and the GIF file format. While they are not immediately interoperable, they are essentially the same thing. The Wikipedi article is perhaps a little confusing/confused on this.
