Walter Archer

Walter Edward Archer C.B. F.R.S.E. (4 July 1855 – 19 August 1917) was a British civil servant, spy and specialist on "the sex life of the salmon".

Walter Archer led the Fisheries Division of the UK government's Board of Agriculture and Fisheries from 1903 to 1912. Between 1908 and 1912, he served as President of the International Council for the Exploration of the Sea, the world's oldest intergovernmental science organization.

His interest in salmon took him to live in Sand, Rogaland, Norway.

In 1912, Archer and his son Hugh were recruited as agents by Mansfield Smith-Cumming, the first director of the Secret Intelligence Service, who gave them the codenames "Sage" and "Sagette", to spy on German ships in Norwegian and Danish waters. Provided by Wikipedia
