Elijah Muhammed (October 7th, 1897 – February 25th, 1975) was the leader of the Nation of Islam and Malcolm X's mentor.  He was regarded as a prophet by his followers and preached that white people were demons and that the black race must separate completely from white America.  At one point, a sex scandal arose in which Muhammed was accused of illegitimately fathering several children.  After Malcolm X travelled to Mecca and renounced Muhammed's racist teachings, he arranged for Malcolm X to be assassinated.
