John Hinde was a colour photo pioneer. “Chances are you’ve never heard of him, but it’s more than likely that you’ll have seen some of his work. Hinde is a (mostly unsung) pioneer of colour photography; overlooked because he spent his time producing holiday postcards.” (source, with very neat samples). He recently became somewhat more widely known because of the Butlin’s Photographs (some of which you can see here). There appears to be a John Hinde website, but it won’t load for me right now…
