Alva Myrdal (January 31, 1902 – February 1, 1986) was a Swedish sociologist and politician. She received the Nobel Peace Prize in 1982.
Born in Uppsala, she first came to public notice in the 1930s, and was one of the main driving forces in the creation of the Swedish welfare state. She coauthored the book Crisis in the Population Question (Swedish: Kris i befolkningsfrågan with Gunnar Myrdal in 1934). The basic premise of Crisis in the Population Question is to find what social reforms are needed to allow for individual liberty (especially for women) while also promoting child-bearing, and encouraging Swedes to have children. While heralding many sweeping social reforms seen as positive for Sweden, the book also incorporated some of the zeitgeist of the 1930s, in its promotion of the idea of racism, eugenics and compulsory sterilization programs. With architect Sven Markelius she designed Stockholm’s cooperative Collective House in 1937 with an eye towards developing more domestic liberty for women.
A long-time prominent member of the Swedish Social Democratic Party, in the late 1940s she became involved in international issues with the United Nations, appointed to head its section on welfare policy in 1949. From 1950 to 1955 she was chairman of UNESCO’s social science section—the first woman to hold such prominent positions in the UN. In 1955-1956 she served as a Swedish envoy to New Delhi, India, Rangoon, Burma (Myanmar) and Colombo, Ceylon (Sri Lanka).
In 1962 she was elected to the Swedish parliament, and in 1962 she was sent as the Swedish delegate to the UN disarmament conference in Geneva, a role she kept until 1973. In 1966 she was also named consultative Cabinet minister for disarmament, an office she held until 1973. A vocal supporter of disarmament, she received the Nobel Peace Prize in 1982 together with Alfonso Garcia Robles. She participated in the creation of the Stockholm International Peace Research Institute, becoming the first Chairman of the governing board in 1966.
