Solomon Tshekisho Plaatje (9 October 1876 – 19 June 1932) was a South African intellectual, journalist, linguist, politician, translator, and writer. The Sol Plaatje Local Municipality, which includes the city of Kimberley, was named after him.

Plaatje was born near Boshof, Orange Free State (now Free State Province, South Africa). He received a mission-education at Pniel. When he outpaced fellow learners he was given additional private tuition by a missionary, Ernst Westphal, and his wife. In February 1892, aged 15, he became a pupil-teacher, a post he held for two years.

As an activist and politician he spent much of his life in the struggle for the enfranchisement and liberation of African people. He was a founder member and first General Secretary of the South African Native National Congress (SANNC), which would later become the African National Congress (ANC). As a member of an SANNC deputation he would travel to England to protest the Natives Land Act, 1913, and later to Canada and the United States where he met Marcus Garvey and W. E. B. Du Bois.

Christopher Eric Hitchens (13 April 1949 – 15 December 2011) was an English American author and journalist whose career spanned more than four decades. Hitchens, often referred to colloquially as "Hitch", was a columnist and literary critic for New Statesman, The Atlantic, The Nation, The Daily Mirror, The Times Literary Supplement and Vanity Fair. He was an author of twelve books and five collections of essays. As a staple of talk shows and lecture circuits, he was a prominent public intellectual, and his confrontational style of debate made him both a lauded and controversial figure.

Hitchens was known for his admiration of George Orwell, Thomas Paine and Thomas Jefferson, as well as for his excoriating critiques of various public figures including Mother Teresa, Bill Clinton, Henry Kissinger and Diana, Princess of Wales. Although he supported the Falklands War, his key split from the established political left began in 1989 after what he called the "tepid reaction" of the Western left to the Rushdie Affair. The September 11 attacks strengthened his internationalist embrace of an interventionist foreign policy, and his vociferous criticism of what he called "fascism with an Islamic face." His numerous editorials in support of the Iraq War caused some to label him a neoconservative, although Hitchens insisted he was not "a conservative of any kind", and his friend Ian McEwan describes him as representing the anti-totalitarian left.

Desmond Mpilo Tutu (born 7 October 1931) is a South African activist and retired Anglican bishop who rose to worldwide fame during the 1980s as an opponent of apartheid. He was the first black South African Archbishop of Cape Town, South Africa, and primate of the Church of the Province of Southern Africa (now the Anglican Church of Southern Africa).

Tutu has been active in the defense of human rights and uses his high profile to campaign for the oppressed. He has campaigned to fight AIDS, tuberculosis, poverty, racism, sexism, homophobia, and transphobia. Tutu received the Nobel Peace Prize in 1984; the Albert Schweitzer Prize for Humanitarianism in 1986; the Pacem in Terris Award in 1987; the Sydney Peace Prize in 1999; the Gandhi Peace Prize in 2005; and the Presidential Medal of Freedom in 2009. Tutu has also compiled several books of his speeches and sayings.

Desmond Mpilo Tutu was born in Klerksdorp, Transvaal, the second of the three children of Zacheriah Zililo Tutu and his wife, Aletta, and the only son. Tutu's family moved to Johannesburg when he was twelve. His father was a teacher and his mother was a cleaner and cook at a school for the blind. Here he met Trevor Huddleston who was a parish priest in the black slum of Sophiatown. "One day," said Tutu, "I was standing in the street with my mother when a white man in a priest's clothing walked past. As he passed us he took off his hat to my mother. I couldn't believe my eyes – a white man who greeted a black working class woman!"
