I call it hearsay because the only person we're hearing these allegations from is von Schuttenbach, who never even met Hipp. She says she "found evidence;" okay, when she publishes and shows us the evidence, then we can make our decisions. Mind you, it might all turn out to be correct, but right now it's hearsay.
Hipp not only turned down his compositions, she turned down his advances. Although Feather’s memoir makes no mention of any sexual tension or personal conflict, Hipp’s biographer, Katja von Schuttenbach, found evidence when she interviewed musicians who knew Hipp; they said that Feather pursued Hipp romantically once she was in the United States. Feather was married and a father at the time, and Jutta was engaged to a Hungarian guitarist named Atilla Zoller. Even though they called off their engagement after he moved to the United States in 1956, Zoller and Hipp remained lifelong friends.
Von Schuttenbach has been researching Hipp since 2005 as part of her master’s thesis, and she intends to publish as a biography. Her account will show how Feather retaliated, turning Hipp, in von Schuttenbach’s words, “from protégée to persona non grata.”
