Guillermo Rawson, Argentinian physician and politician (d. 1890)

Dr. Guillermo Rawson (24 June 1821 – 20 January 1890) was a medical doctor and politician in nineteenth-century Argentina. In 1862, when he was the Interior Minister of Argentina, he met Captain Love Jones-Parry and Lewis Jones, who were on their way to Patagonia to investigate whether it was suitable for the creation of a Welsh settlement there. Rawson came to an agreement with them, and this resulted in the creation of a colony in the Chubut Valley in the following years. The city of Rawson, the capital of the province of Chubut, was named after him.
