Sir Evelyn John Ruggles-Brise KCB (6 December 1857 – 18 August 1935)[1] was a British prison administrator and reformer, and founder of the Borstal system.

At Oxford, Ruggles Brise knew Montague John Druitt, the man named as the prime suspect in the Jack the Ripper case by Chief Constable Melville Macnaghten in a report written for the Home Office in 1894.

Ruggles Brise was also a lifelong friend of Basil Thomson who attended New College, Oxford at the same time as Montague Druitt and who succeeded Melville Macnaghten as Head of CID at Scotland Yard in 1913.

The long-serving incumbent chairman of the Prison Commission, Sir Edmund du Cane, was criticised by Gladstone Committee in 1895, and resigned.

His main task was implementing the report of the Gladstone Committee, to combine reform with deterrence, and to separate youths from older men in adult prisons.

He was advanced to a Knight Commander of the order (KCB) in the 1902 Coronation Honours list published on 26 June 1902,[2][3] and invested as such by King Edward VII at Buckingham Palace on 24 October 1902.
