Admiral Sir Edmond John Warre Slade KCIE KCVO (20 March 1859 – 20 January 1928) was a Royal Navy officer who served as Director of Naval Intelligence.

[1] Promoted Rear-Admiral in 1908,[5] he represented the Admiralty at the International Maritime Conference (December 1908 to February 1909) which resulted in the Declaration of London.

The expedition gave a positive report and the British Government bought a 51% stake in the Anglo-Persian Oil Company just before the outbreak of the First World War.

As part of the agreement the Government had the right to appoint two directors, and Slade became one of these, a position he held until his death.

In 1887 Edmond married Florence Madeleine, eldest daughter of Mr James Carr Saunders of Milton Heath, Dorking (but born in Reigate, Surrey in 1870), and had two daughters: Rhona Warre and Madeline Warre Slade.
