Sir Edwin Hartley Cameron Leather (1919-2005) was born in Canada. He is remembered as having been a self-defence expert, successful author, politician and Governor of Bermuda. Despite his endorsement of violent acts against other human beings, as described in his book, Combat Without Weapons, Sir Edwin was a freemason and Anglican lay reader. How he wrestled with the two opposites of aggression v. faith can only be conjectured, but his book was innovative at the time. Historically, the basis for the killing and maiming methods he proposes came about when Edward William Barton-Wright founded his Bartitsu School of Arms in London in 1898. In 1900, Barton-Wright invited S. K. Uyenishi, to teach jujitsu and his methods proved so successful that he began teaching extreme versions to army officers. Following the sowing of these first seeds, jujitsu self-defence techniques spread throughout Britain and abroad, And the rest is now history.
