Sven Kalisch

Sven Kalisch is a German scholar, formerly an Islamic theologian. He converted to Islam at age 15, became the first in Germany to hold a chair in Islamic theology, then in 2008 announced that he had come to the conclusion that the Islamic prophet Muhammad probably never existed. Official Islamic groups in Germany have referred to him as an apostate. Germany's Muslim Coordinating Council withdrew from the advisory board of professor Kalisch's centre.
