According to Rick Hines and Keith Harmon Snow writiting in 2007: "Maurice Tempelsman has a long and bloody history in Africa. When Congo’s first Premier, Patrice Lumumba, pledged to return diamond wealth back to the newly independent Congo in the early 60’s, Tempelsman, who began with De Beers in the 1950’s, helped engineer the coup d’etat that consolidated the dictatorship of 29 year-old Colonel Mobutu, and the coup against Ghana’s Kwame Nkrumah; diamonds were at stake in each."
