There was no zsh "project"; it was developed by a single student (Paul Falstad) at Princeton for use by himself and other students on the time-sharing system there. There weren't outside contributors until a few years later after the sources appeared on the comp.sources.unix newsgroup. The goals were not at all similar. Bash was an effort to re-create the Bourne shell under the GPL; zsh was an effort to introduce structured shell language and scripting to csh users.
