The thought hit me the other day as to who designed the GG1 in the first place. Raymond Lowey refined the initial design which made the GG1 what it was.
From Wikipedia
"The first designer for the GG1 project was industrial designer Donald Roscoe Dohner, who produced initial scale styling models, although the completed prototype looked somewhat different.[15][16] At some point, PRR hired famed industrial designer Raymond Loewy to "enhance the GG1's aesthetics."[8][15]"
