Siobhan Nash-Marshall holds the Mary T. Clark Chair of Christian Philosophy at Manhattanville College. Author of many academic books and articles on metaphysics and the problem of evil, she also has written books and articles for the general public – Joan of Arc: A Spiritual Biography and What It Takes to be Free: Religion and the Roots of Democracy. In recent years, Nash-Marshall has devoted a lot of attention to genocide and genocide negationism. The Sins of the Fathers is her first book-length treatment of the topic. After the breakout of the war in Syria, Nash-Marshall and some friends founded the Christians In Need Foundation (CINF), through which they attempt to help the ancient Christian cultures of the world which are presently in peril.
