Few men have acquired so scandalous a reputation as did Basil Zaharoff, alias Count Zacharoff, alias Prince Zacharias Basileus Zacharoff, known to his intimates as “Zedzed.” Born in Anatolia, then part of the Ottoman Empire, perhaps in 1849, Zaharoff was a brothel tout, bigamist and arsonist, a benefactor of great universities and an intimate of royalty who reached his peak of infamy as an international arms dealer—a “merchant of death,” as his many enemies preferred it.
In his prime, Zaharoff was more than a match for the notorious Aleister Crowley in any contest to be dubbed the Wickedest Man in the World. Still remembered as the inventor of the Systeme Zaharoff—a morally bankrupt sales technique that involved a single unscrupulous arms dealer selling to both parties in a conflict he has helped to provoke—he made a fortune working as a super-salesman for Vickers, the greatest of all British private arms firms, whom he served for 30 years as “our General Representative abroad.” He expressed no objection to, and indeed seemed rather to enjoy, being referred to as “the Armaments King.”
Sources on Zaharoff's life and exploits are varied, incomplete, and sometimes suspicious. Mike Dash of Smithsonian's Past Imperfect blog puts together what we know -and don't know- about the strange life of the mysterious Mr. Zedzed. Link
