The Institute of Biology (IoB) was a professional body for biologists, primarily those working in the United Kingdom. The Institute was founded in 1950 by the Biological Council: the then umbrella body for Britain's many learned biological societies. Its individual membership (as opposed to the individual membership of its affiliates) quickly grew; in the late 1990s it was as high as 16,000 but declined in the early 21st century to 11,000. It received a Royal Charter in 1979 and it held charitable status.The IoB was not a trade union, nor did it have the regulatory power over its membership (like the General Medical Council) although it did have the right to remove a member's Chartered status and was empowered by its Royal Charter to represent Britain's profession of biology.
