Zimmer was a male Donican and a governmental leader in a regional area. In 2267, Nyota Uhura read news reports extolling his five years of community leadership, focusing on how he'd beautified the community -- accomplishments that previously had been credited to a man named Nyshev. Shortly afterwards, however, Uhura discovered Zimmer's name stricken from all official records. (TOS short story: "See No Evil")
