A Polish girl, desperate and vengeful after failing her examination, took a gun, concealed herself in [Alfred] Werner’s garden, and awaited his return. He arrived home. She fired and missed. Werner calmly turned to her and remarked, ‘Your aim is no better than your knowledge of chemistry.’
Werner (1866 – 1919) was a chemist and major contributor early in the field, who won the Nobel Prize for Chemistry in 1913. And he was also, apparently, very cool under fire.
