So far he has deliberately avoided exposure, it's difficult to know who he is. There are only two photos of him in circulation.

Here goes some interesting and horrifying details of Abu Bakr Al-Baghdadi, the world's most dreaded terrorist:
Abu Bakr Al-Baghdadi is the leader of ISIL, an Islamic extremist group in western Iraq and north-eastern Syria, self-described as the “Islamic State”.
He ascended to his position by a process of elimination after the previous Sunni militant leaders in Iraq, Abu Musab Zarqawi and his successors, Abu Omar al-Baghdadi and Abu Ayub al-Masri, were killed.
