How can you guys forget Roger Nichols that engineered Donald Fagen's "The Nightfly"...
I think Bob Ludwig, in my original list, did the mastering on Nightfly...I just couldn't list everyone, I guess.
George Martin is a good suggestion....did much of the Beatles stuff - a little too heavily panned (stuff seems to come out one speaker or the other) for my tastes but great stuff nevertheless - Sergeant Pepper is an all time classic - groundbreaking in almost every way.
