Well, too bad he's passed away (a couple of years ago), but I would've suggested Tom Dowd.
He's produced/engineered most of the legends. Thelonious Monk, Ray Charles, Aretha Franklin, John Coltrane, Dizzy Gillespie, Bobby Darin, Cher, Booker T & MG's, Otis Redding, Cream, Allman Bros Band, Delaney & Bonnie and Friends, Derek & The Dominoes, Rod Stewart, Dusty Springfield, Lynyrd Skynyrd, The Coasters, Lavern Baker, Herbie Mann, Bee Gees, Jackie DeShannon, The Drifters...well, look at the list yourself:
