Sherman Loudermilk was the Art Director, apparently, on several hit TV shows, includingSimon & Simon and The A-Team. He is also credited as Art Director on Galactica 1980. If he did anything on BSG, he's not credited for it on IMDb.com.
BTW - the obit you link to requires an account to see it, so I don't know what it said. I just looked him up.
