Mordecai Meirowitz was an Israeli postmaster and telecommunications expert who invented the code-breaking board game Master Mind.
Having been rejected by the leading games companies, he managed to interest a Leicester-based Company, Invicta Plastics, which restyled and renamed the game.
Released in 1971, the game sold over 50 million sets in 80 countries, making it the most successful new game of the 1970s.
