Sir Isaiah Berlin (6 June 1909 – 5 November 1997) was a Russian-British social and political theorist, philosopher and historian of ideas. Although averse to writing, his improvised lectures and talks were recorded and transcribed, with his spoken word being converted by his secretaries into his published essays and books. **Source**: [Isaiah Berlin](https://en.wikipedia.org/wiki/Isaiah_Berlin) on Wikipedia.
