Gustav Harald Edelstam (March 17, 1913 – April 16, 1989) was a Swedish diplomat. During World War II he earned the nickname Svarta nejlikan ("the Black Pimpernel," a reference to the Scarlet Pimpernel) for helping hundreds of Norwegian Jews, SOE agents, and saboteurs escape from the Germans. During the early 1970s he was stationed in Santiago, Chile, and became known as the "Raoul Wallenberg of the 1970s" when he helped over 1,200 Chileans, hundreds of Cuban diplomats and civilians, and 67 Uruguayan and Bolivian refugees escape persecution by dictator Augusto Pinochet.
