Mark Adler wrote the decompression part. We developed this program as a replacement for compress because of the Unisys and IBM patents covering the LZW algorithm used by compress. These patents made it impossible for us to use compress, and we needed a replacement. The superior compression ratio of gzip is just a bonus.
