Alleged Bronte sisters photo

I am always fascinated by these mysteries, but in my experience they usually get involved in so much minutiae that the central question becomes lost. I have no particular knowledge of the Brontes, but as a photo historian, this looks to me to be an attractive if otherwise normal c. 1850s-1860s ambrotype. It is taken outside which is not unusual for a British ambrotype but very unusual for a daguerreotype. The sharpness does not make it appear to be a copy. The dress looks very much from the…See More

Bronte Sisters Photo Discovery

Bronte MysteryThere are no known photographs of the Bronte Sisters but an 'alleged' photo of them has been discovered.It needs authenticating. Can anyone help the researcher?The photo is thought to be a Collodion copy of a Daguerreotype. The photographer who they think copied it is John Stewart of Pau, France & London, England. He was brother-in-law of Sir John Herschel.The original photo must have been taken before Emily died in 1848.Why is there is no backdrop, just a brick wall?How to…See More

Kenny,
Looking forward to adding it to my chronology. By the way I have another segment of my site, not yet online; for now I am calling it:
"Photography: essential texts"
I have several published and unpublished texts which I intend to put on line as PDF files [ This is the only format I have found, to date, which does not lose footnotes if you transfer texts from Word] Texts such as the Wedgwood-Davy paper; An Account of the Art…etc.,; Waterhouse: History of the Camera Obscura, History of the Salts of Silver; Lady Eastlake on Photography; Maskelyne: The Future of Photography written 1846-7: Niepce: correspondence 1826 on relating to his English visit - translated in English Plus several others written by yours truly.

BTW, we have a carte de visite of Ernest Lacan with an envelope (dated?) sent to Talbot when he stayed in a Parisian hotel. Would this possibly help your chronology? Yes! is it dated?

Dear Kenny and Jenny,
I have recently spent some time with Terry Bennett - we share a common interest in Jocelyn, that is William Nassau. You probably know of the two albums he has containing the Jocelyn and Vacher material centered around Shanghai in the mid/late 1850s. Over the last 5 years i have had an interest in the first photographers in Taiwan and this has, of course, now spread to included the treaty ports and Shanghai in particular. Terry informed me that you might have some related Jocelyn material.

I am currently working on two Vacher albums that are in a local collection and attempting to reconcile the contents of the two related collections.

I am sorry that I have not been in touch for some time - a lot of water has gone under the bridge so to speak and I now have not connection with Lacock or the National Trust; I am once again a free agent.

Kind regards

michaelg [Michael Gray]
