Edwin Montagu

Edwin Samuel Montagu PC (6 February 1879 – 15 November 1924) was a British Liberal politician who served as Secretary of State for India between 1917 and 1922. Montagu was a "radical" Liberal and the third practising Jew (after Sir Herbert Samuel and Sir Rufus Isaacs) to serve in the British cabinet.

He was primarily responsible for the Montagu–Chelmsford Reforms which led to the Government of India Act 1919, committing the British to the eventual evolution of India towards dominion status. Provided by Wikipedia
