In a typical "early internet" straightforward way, you can just leave out the "dmr" from the URL and get a listing of some other ex-Bell Labs employees. Although at least two other ones I know about (Ken Thompson and Rob Pike) are missing. Some who you might know that are there include Brian Kernighan (the "K" in "K&R C", co-author of "The C Programming Language" and later "The Go Programming Language") and Russ Cox (I think he's the only ex-Bell Labs person left working on Go at Google after Thompson and Pike retired?).
