Van Wyk was born in Baragwanath Hospital in Soweto. When he was a little older, his family moved to Riverlea, a suburb outside of Johannesburg. He was educated at Riverlea High School in Riverlea, Johannesburg, where he lived until 2005. His autobiographical novel Shirley, Goodness & Mercy details his childhood growing up in Riverlea. The follow-up novel, Eggs to Lay, Chickens to Hatch, continues this theme. Van Wyk worked as a clerk for the independent South African Committee for Higher Education as an educational writer of accessible literature for new readers. He was also editor of Staffrider from 1981 to 1986 and in 1980 started the short-lived Wietie magazine with Fhazel Johennesse. One of Van Wyk’s most notable achievements was his abridgement of Nelson Mandela’s Long Walk to Freedom for children. Van Wyk died in Johannesburg on 3 October 2014.
Writing
During the literary explosion among black writers that followed the Soweto uprising in 1976 van Wyk published a volume of poetry, It Is Time to Go Home, that won the 1980 Olive Schreiner Prize. The book is characterized by the preoccupations of other Soweto poets such as Mongane Serote, Sipho Sepamla, and Mafika Gwala and employs the language of defiance and assertion in poetry that reveals at all times the Black Consciousness of the era. In 1981 he received the Maskew Miller Longman Literature Award for black children's literature for A Message in the Wind, the story of two boys who travel in their homemade time machine to their shared tribal past of 1679. Other children's stories include Peppy 'n Them and Petroleum and the Orphaned Ostrich. He has written books for neo-literate adults, such as The Murder of Mrs. Mohapi, My Cousin Thabo, Take a Chance, My Name is Selina Mabiletsa, and Sergeant Dlamini Falls in Love, biographies of Sol Plaatje and Oliver Tambo for teenagers, and adaptations of works by Bessie Head, Sol Plaatje and Can Themba. He won the 1996 Sanlam Literary Award for his short story "Relatives", published in Crossing Over. The Year of the Tapeworm is an adult novel and warns of government control of the media. His latest work Eggs to Lay, Chickens to Hatch details childhood memories about growing up in Riverlea and his colourful interactions with the men and women who lived the African proverb that "it takes a village to raise a child".
