who was the head of the medellin cartel
Medellín Cartel The Medellín Cartel was a ruthless, highly organized and much-feared Colombian drug cartel originating in the city of Medellín, Colombia. The drug cartel operated throughout the 1970s and 1980s in Bolivia, Colombia, Central America, Peru, and the United States, as well as in Canada and Europe. It was founded and run by Ochoa Vázquez brothers Jorge Luis, Juan David, and Fabio, together with Pablo Escobar, George Jung, Ishaq Velasco, Carlos Lehder and José Gonzalo Rodríguez Gacha. By 1993, the resistance group, Los Pepes (or PEPES), controlled by the Cali Cartel, and the Colombian government, in collaboration with the Cali Cartel, right-wing paramilitary groups, and the United States government, had dismantled the Medellín Cartel by imprisoning or assassinating its members.
Merck & Co. In 1953, Merck & Co. merged with Philadelphia-based Sharp & Dohme, Inc., founded by Alpheus Phineas Sharp and Carl Friedrich Louis Dohme in 1845, becoming the largest US drugmaker.[6][7] The merger combined Merck & Co.'s strength in scientific research and chemical manufacturing with Sharp & Dohme's sales and distribution system and its marketing expertise. The combined company kept the trade name Merck in the United States and Canada, and as Merck Sharp & Dohme (MSD) outside North America. In 1965 Merck & Co. acquired Charles E. Frosst Ltd. of Montreal, Canada (founded 1899) and created Merck-Frosst Canada, Inc., as its Canadian subsidiary and pharmaceutical research facility. Merck & Co. closed this facility in July 2010,[8] and the company was renamed Merck Canada in 2011.
