Retired diplomat, Hans Blix, is most well-known for his involvement in the United Nation's disarmament and monitoring program of nuclear weapons in Iraq.
The 82-year-old Swede was called out of retirement by then former Secretary General, Kofi Annan in 2000 to help lead the UN's effort in Iraq.
As head of the United Nations Monitoring, Verification and Inspection Commission, Blix was responsible for taking inspection teams into Iraq to make sure that the country was following proper disarmament guidelines.
During his tenure as the chief inspector, Blix admonished former leader Sadaam Hussein for playing 'cat and mouse games' and for a decade of unnecessary sanctions.
Blix also clashed with the Bush administration over the reasons to go to war.
After leaving the United Nation's role in 2003, Blix went on to write two books on his role in Iraq.
This week, Blix will be appearing at the Iraq Inquiry in the United Kingdom to testify over his involvement in the lead up to war.
