The New Zealand inventor of the disposable syringe and tranquiliser gun died on May 4 in Canterbury.  Colin Murdoch featured last year in a series of New Zealand Post stamps about 'Clever Kiwis'.  A low achiever at school, Colin's vivid imagination and ability to conceptualise and design his thoughts saw him achieve 40 patents and save the lives of millions through his inventions. See The NZEdge or Wikipedia for the amazing life story of a quiet New Zealander.
