URSI: The international scientific radio union

The International Scientific Radio Union originated in a small meeting in Brussels in 1913; thus, it was celebrating its Golden Jubilee, or 50th anniversary, at its XIVth General Assembly in Tokyo in September, 1963. The following paper presents a very brief history of the URSI, with an account of its scientific objectives and its activities in relation to other scientific and technical bodies in the radio and allied fields. For a comprehensive account of the development and international work of the URSI, the reader may be referred to a volume shortly to be published.
