Karlheinz Deschner

Karl Heinrich Leopold Deschner (23 May 1924 – 8 April 2014) was a German researcher and writer who achieved public attention in Europe for his trenchant and fiercely critical treatment of Christianity in general and the Catholic Church in particular, as expressed in several articles and books, culminating in his 10 volume ''Christianity's Criminal History'' (''Kriminalgeschichte des Christentums'', Rowohlt Verlag, Reinbek).
