Re: [TUHS] Fwd: [SIGCIS-Members] Need help identifying a photo

Can someone here ID the mystery person? Embarrassingly, CHM has the person misidentified as well. -------- Forwarded Message -------- Subject: [SIGCIS-Members] Need help identifying a photo Date: Wed, 27 Jan 2016 16:46:45 +0000 From: Ceruzzi, Paul &lt;CeruzziP(a)si.edu&gt; To: members(a)lists.sigcis.org &lt;members(a)lists.sigcis.org&gt; There is a famous photo on Wikimedia commons, of what purports to be Ken Thompson & Dennis Ritchie in front of a PDP-11, presumably working on UNIX. The problem is that the seated person doesn’t look like either of them. And he is clean-shaven. Could it be Bjarne Stroustrup? Does anyone recall seeing T&R w/o facial hair? Any help in tracking this down would be much appreciated! The photo has been reprinted in many places, and I’d like to track this down before I inadvertently propagate an error. https://commons.wikimedia.org/wiki/File:Ken_Thompson_(sitting)_and_Dennis_R… Paul E.
