Since 2006, Frank Lehmann-Horn, the Director of the Division of Neurophysiology at the University of Ulm, had been fighting against various forms of cancer. On May 8, 2018, after an apparently successful bone marrow transplantation, he passed away owing to the sequelae of leukemia. The community of German researchers into neuromuscular diseases has lost one of its most distinguished members. In particular his co-workers at the University of Ulm miss him as their pioneer and sincere friend.
