This book is about the importance of nuclear disarmament and the work pursued by Alva Myrdal, a pioneering social activist, diplomat, cabinet minister, and disarmament negotiator. She was awarded the Nobel Peace Prize in 1982 together with Alfonso Garca Robles "for their work for disarmament and nuclear and weapon-free zones". Prominent academics, politicians and practitioners have contributed reflections on Myrdals achievements and their impact on the world today. Furthermore, a sample of Myrdals own writings on nuclear disarmament are included, as well as significant speeches and a bibliography of her publications on nuclear matters. Alva Myrdal was born in Uppsala, Sweden, in 1902, graduated from college in Stockholm in 1924, and continued higher education at Uppsala University in the 1930s. She was a prolific author and reformer, specializing in social affairs, womens roles and nuclear disarmament. She was Swedens Ambassador to India in the 1950s, for Nuclear Disarmament in the 1960s and 1970s, and a member of the Cabinet 1967-1973. Her most well-known works are "The Game of Disarmament" (1976), "Nation and Family" (1941), and "Women's Two Roles" (1956, with Viola Klein). Her book "The Game of Disarmament" (1976) is a key work in disarmament.
