Raymond Sackler KBE (February 16, 1920 – July 17, 2017) was an American physician and businessman. He acquired Purdue Pharma together with his brothers Arthur M. Sackler and Mortimer Sackler. Purdue Pharma is the developer of OxyContin, the drug at the center of the opioid epidemic in the United States. Sackler and his family have been linked to the rise of direct pharmaceutical marketing and the opioid crisis. The Sackler family's philanthropy has been characterized as reputation laundering from profits acquired from the selling of opiates.
