Throughout the 70s and 80s he was a symbol of the anti-apartheid movement in his home country South Africa. The cleric was awarded Nobel Peace Prize in 1984, and became the first black head of the Anglican Church of South Africa.
Not always popular, he had many enemies during decades of racial turbulence, but his faith, and trust in the universal goodness of humanity, carried him through.
Tutu celebrated with the rest of South Africa when in 1994 the apartheid system was dismantled. Since then, he has had more freedom to spread his universal message of tolerance and optimism – the essential good of man, in the face of evil.
Tutu’s religious and moral code, and his high-profile status, placed him ideally to sit on the TRC – Truth and Reconciliation Commission – a body which eased South Africa in to its new democratic era, with a very simple concept: forgiveness granted in exchange for the truth.
Nowadays, Tutu’s attentions turn to the global community and he throws himself in to many active causes on the international stage.
And This week he is coming out with his new Children's Bible.
Last week on Thursday Tutu announced he will retire from public life in October, when he turns 79 years old. "Instead of growing old gracefully, at home with my family - reading and writing and praying and thinking - too much of my time has been spent at airports and in hotels," the Nobel laureate said in a statement. "The time has now come to slow down, to sip Rooibos tea with my beloved wife in the afternoons, to watch cricket, to travel to visit my children and grandchildren, rather than to conferences and conventions and university campuses," he said.
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.
Here's your chance to quiz Hans Blix.
Do you want to know about what it was like being part of the inspection monitoring process in Iraq? Does he have any doubts? Was war the right decision?

As the U.S. state of Arizona prepares to enact a new law which will allow police officers to ask for proof of residency from anyone being investigated for a crime, the spotlight has shifted on the role immigration plays on developed countries around the world.

Opponents of Arizona's SB 1070 say the measure is discriminatory and invites racial profiling, but supporters say it's necessary to curb the flood of illegal immigrants in the border state.
On July 21, ten nations joined Mexico's opposition and signed a declaration expressing their "strong condemnation and profound rejection of the law," according to Senate President Carlos Navarrete Ruiz.
As countries around the world voice their opinion on the Arizona law, the debate brings into question the role that immigration can play in a country and whether it either helps or hinders.
Countries like Canada have gained a strong reputation for embracing immigration from countries around the world and today, Canada is one of the most multicultural and diverse nations on earth.
Other countries like the United Kingdom and Australia have had more difficult paths to multiculturalism.
In Australia, Pauline Hanson's One Nation party won a handful of seats in the Queensland parliament on the back of an anti-immigration message.
In the United Kingdom, Nick Griffin's British National party also received a great deal of attention for their right-wing policies, but remains relatively ignored in mainstream politics.
We want to know what you think.
Are you an immigrant? How have you found your transition from one country to another? Do you think the majority of people are welcoming? Do you oppose immigration? Should there be tougher regulations in your country?
