Mandela and Tambo was a South African law firm established by Nelson Mandela and Oliver Tambo in Johannesburg in late 1952. It was the first firm in the country to be run by black partners.
In August 1952, Mandela had opened his own firm:210 but, after just several months, he invited Tambo to join him in the establishment of Mandela and Tambo in two small rooms at Chancellor House, the building housing the headquarters of the African National Congress. The firm was inundated with clients seeking redress from acts of the oppressive apartheid regime. Tambo would do much of the paperwork in the office whilst Mandela did most of the advocacy before the magistrates in the courts opposite.:212
The firm was closed down in 1960 as Mandela faced charges of treason and Tambo fled the country. The building was later gutted by fire and was an urban slum for many years before being completely refurbished and opened as a museum and archive in 2011.
