John Dickinson
Strahan was a close friend of the inventor John Dickinson (1782–1869) and his family. He recommended the young John Dickinson as a apprentice to the stationer Thomas Harrison in London and supported him financially on several occasions, amongst others to establish himself as a paper trader in 1805 and to set up a paper producing company in 1809, which later evolved into the leading paper and stationery company John Dickinson &amp; Co. Ltd.
