Bertil Ohlin, Swedish economist and politician, Nobel Prize laureate (b. 1899)
Bertil Gotthard Ohlin (Swedish: [ˈbæ̌ʈːɪl ʊˈliːn]) (23 April 1899 – 3 August 1979) was a Swedish economist and politician. He was a professor of economics at the Stockholm School of Economics from 1929 to 1965. He was also leader of the People's Party, a social-liberal party which at the time was the largest party in opposition to the governing Social Democratic Party, from 1944 to 1967. He served briefly as Minister for Trade from 1944 to 1945 in the Swedish coalition government during World War II. He was President of the Nordic Council in 1959 and 1964.

Ohlin's name lives on in one of the standard mathematical models of international free trade, the Heckscher–Ohlin model, which he developed together with Eli Heckscher. He was jointly awarded the Nobel Memorial Prize in Economic Sciences in 1977 together with the British economist James Meade "for their pathbreaking contribution to the theory of international trade and international capital movements".
