Information and discussion on all aspects of British photographic history
My great great grandfather was in business with Antoine Claudet (Claudet & Houghton) in the 1840s and after Claudet died in the 1860s when the company became Houghton's Ltd. To cut a long story short, by the end of that century, around 1900, Houghton's evolved into the Ensign Camera Co with a factory in Walthamstow, employing around 700 work force.
I have one photo of my ancestor taken in 1848 and another which I believe is Antoine Claudet. At present I cannot upload the photos onto my computer - I don't have the know how!
For more information, the museum in Walthamstow has an extensive portfolio relating Houghton's and Ensign. You may be able to find something useful there.
