"Steve Guttenberg," unless there is a much more intellectual seventh _Police Academy_ sequel uncovering his secret time traveling invention, probably didn't contribute very much to the printing press.

"Johannes Gutenberg," in spite of not appearing in _Police Academy 7: Mission to Moscow_ or kissing Sharon Stone in _Police Academy 4: Citizens on Patrol_ (the true highlight of the series, as many aficionados will readily attest), probably deserves our thanks instead.
