Password dilemma

I vowed to get "it" under control.  I cut 4/5 slips, quickly wrote them down for each site with anagrams for the title.  There must be 60 slips.  I've got them "under control" ; but what is "S DC"?  I got the password but not the slightest notion of of whom "S DC" might be.  I Googled for 15 minutes but did not "spot" it.  (It has to do with photography, image editing, SW, computers, cameras...alas, I am named well.
