Jannie Momberg

Jan Hendrik "Jannie" Momberg (27 July 1938 – 7 January 2011) was a South African politician, businessman, and sports administrator who served in the South African Parliament from 1989 to 2001. A former member of the National Party (NP), Momberg's opposition to apartheid led him to become a founding member of the Democratic Party in 1989, and he joined the African National Congress (ANC) in 1992.

Born in Stellenbosch to a conservative Afrikaans family, Momberg inherited half of Middelvlei wine estate and subsequently purchased Neethlingshof Estate. Alongside his business career, he was a sports administrator in the Cape Province and later nationally as a member of the board of the South African Athletics Association. He joined the National Party in 1957 and remained a member until 1987, though by the mid-1960s he was openly critical of aspects of the party's policy of apartheid. By the mid-1980s, Momberg had publicly called for the abolition of apartheid.

In the 1989 general election, he was elected to the House of Assembly, representing the Democratic Party in Simonstown. From 1992, he sat as an independent after defecting to join the recently unbanned ANC. The next general election in 1994 was held under universal suffrage with the ANC's participation and Momberg was elected to an ANC seat in the post-apartheid National Assembly. He served as the party's programming whip until June 2001, when President Thabo Mbeki appointed him to a diplomatic posting. He served as South African Ambassador to Greece from 2001 to 2006.
