On 1^st April 2011, the world of neurology said a sad farewell to Professor Hubert Kwieciński, a medic of exceptional quality who left a mark on all those who knew him – his colleagues, students as well as friends. Nowhere will the loss be felt more than at the Medical University of Warsaw where Professor Kwieciński began his academic career and where from 1990 he headed the Department of Neurology and the Neurology Clinic.
