In Memoriam Marc Yor Séminaire de Probabilités XLVII This volume is dedicated to the memory of Marc Yor who passed away in 2014. The invited contributions by his collaborators and former students bear testament to the value and diversity of his work and of his research focus which covered broad areas of probability theory. The volume also provides personal recollections about him and an article on his essential role concerning the Doeblin documents. With contributions by P. Salminen J Y. Yen & M. Yor; J. Warren; T.
