Kabelo "Sello" Duiker, (April 13, 1974 – January 19, 2005), was a South African novelist. His debut novel, Thirteen Cents, won the 2001 Commonwealth Writers Prize for best first book written by an African writer. He also worked in advertising and as a screenwriter, at the time of his death he was working as an editor of drama for SABC1.
Duiker, the eldest of three brothers, was born in Orlando, Soweto at the height of apartheid. Coming from a moderately wealthy family he was sent to a public school, where he was one of the very few black pupils. During his school-years the schools in South Africa were very much at the centre of the anti-apartheid movement. This personal experience of the social-struggles influenced Duiker greatly, his novels treated racial difference as largely immaterial, being basically cosmetic.
Duiker received a degree in journalism from Rhodes University, he also briefly studied at the University of Cape Town. He suffered a nervous breakdown in 2004 prior to committing suicide by hanging himself in Northcliff, Johannesburg, in January 2005. His death came a month after that of his contemporary Phaswane Mpe.
