Here's some sketchy evidence for you:
Per a factory sales brochure, "The Forte Model 40 was developed by Nelson Pass to combine..." And from Audio magazine, November 1991, "The model 4 (power amp) was designed by a team led by Nelson Pass..."
That said, I remember reading soemwhere that Michael Bladelius worked on the remote controlled F44 and the last generation, XLR equipped, Forte power amps. He is now linked with Primare; see

Enjoy your research.
