Sampson Mordan (1790 – 9 April 1843) was a British silversmith and a co-inventor of the first patented mechanical pencil. During his youth, he was an apprentice of theinventer and locksmith Joseph Bramah who patented the first elastic ink reservoir for a fountain pen
In 1822, Mordan and his co-inventor JohnIssac Hawkins filed the first patent in Great Britain for a metal pencil with an internal mechanism for propelling the graphite "lead" shaft forward during use, as an improvement on the less complex lead holders that merely clutched the pencil lead to hold it into a single position.
