The Reith Lectures is a series of annual BBC radio lectures given by leading figures of the day. They are commissioned by the BBC and broadcast on Radio 4 and the World Service. The lectures were inaugurated in 1948 to mark the historic contribution made to public service broadcasting by Lord Reith, the corporation's first director-general. Reith maintained that broadcasting should be a public service that aimed to enrich the intellectual and cultural life of the nation. It is in this spirit that the BBC each year invites a leading figure to deliver the lectures. The aim is to advance public understanding and debate about issues of contemporary interest. The first Reith lecturer was the philosopher and later Nobel laureate, Bertrand Russell. The first female lecturer was Dame Margery Perham in 1961. The youngest Reith lecturer was Colin Blakemore, who was 32 in 1976 when he broadcast over six episodes on the brain and consciousness.

The Reith Lectures archive

In June 2011 BBC Radio 4 published its Reith Lectures archive. This included two podcasts featuring over 240 lectures from 1948 to the present day as well as streamed online audio, and the complete written transcripts of the entire Reith Lectures archive: The BBC found that some of the audio archive of the Reith Lectures was missing from its library and appealed to the public for copies of the missing lectures.
