Well, you can be as firm as you like about the claim, it's still reads as if Dieter Rams worked for Apple.

Dieter Rams no doubt had significant influences and admiration for those who shaped his work and design philosophy, should we credit those people as being behind Apple also? How far should we go? Perhaps we need to point out da Vinci is also one of the men behind Apple's design philosophy.

Seems reasonable to suggest "the man behind" is generally understood to mean "the person directly responsible for".
