On 29 December 2016, Google marked the 250th birthday of William Macintosh’s nephew, Charles, with a Google Doodle. Charles (1766–1843) was the inventor of the fabric waterproofing process that gave rise to the eponymous Macintosh (later Mackintosh) coat.
In my research on William, Charles is significant insofar as he was the subject of a useful privately printed biography, written by his son George, that contains, as an appendix, a short account of William’s life. This account is based, in part, on family correspondence that is now lost and is particularly valuable in fleshing out William’s period of exile in Germany towards the end of his life. Had William’s nephew not found fame through his invention, it is unlikely that any of the valuable biographical detail concerning William’s life would have been recorded in this way.
In 2014 I visited Charles’s grave at Glasgow Cathedral with his descendent, Deirdre Grieve (who was kind enough to alert me to the Google Doodle).
