'Mention of the Levy dry plates and cameras can be found in Philadelphia Photographer  v.16, p. 95 (1879). As the notice appears early in 1879 and states that Levy is well known for his dry plates, it is quite evident that he was making them as early as 1878 and possibly sooner.' Here is described where Taft found the reference. Page 503.

'In fact the earliest manufacturers of dry plates (Levy and Carbutt) sold their products rather largely to amateurs. Early in 1879, Levy followed up his plates with a small camera designed for amateurs trade. This was described as “a unique little camera for dry plates- and he (Levy) offers camera and lens for $12.00 for plates 4x5 inches: For this sum a half a dozen plates, developer, pyro, and hypo are included, with full instructions for working the same". The following year T.H Blair of Chicago place on the market a camera for “amateurs photographers, college boys and artists “ which became well known.'. Page 375.

To the editor
Sir; Your always valuable and wellcome Journal came to hand,as you are always trying to keep your readers well posted, you should add a P. S. to M. S.A. Crawford's  letter ( p.78) to the effect that Mr Official  Photographer C.D. Arnold by name ( very glad to take pictures ..etc. against pay..etc) does not even answer my in quiry to effect. Personally I had written three times to him without being able to obtain an answer . My first letter dating November 12 last. The above may prove interesting to other parties  who may be tempted to ask Mr. C.D. A. for any reference or negatives.
By the way, Mr. Editor, What do you say to the american generosity towards allowing photographers on the Exhibition grounds?. You were at the time very hard against French meannes in 1889.Let me remind you of the rules that existed then . Twenty francs , or 16 s. , for one's day work , and no restriction to sizes or cameras renewed if weather unfavorable , or 300 Fr. , ( 12 l.) for the whole time the exhibition was open
I am yours..etc

Lorsqu’Albert Lévy (1891-1976) prend la direction de la maison d’édition La Librairie centrale des Beaux-Arts en 1919, celle-ci jouit d’une notoriété certaine depuis la fin du xixe siècle. Les publications d’A. Lévy, aux rênes de l’entreprise familiale jusqu’en 1936, s’inscrivent dans une période riche en évolutions critiques, tant pour le renouveau des arts décoratifs que pour celui de la reconnaissance de la photographie. Le fonds d’archives photographiques de la maison d’édition, conservé au musée des Arts décoratifs de Paris, se trouve ainsi au croisement de cercles complémentaires : ceux des arts décoratifs du début du xxe siècle et de la photographie. Dès 1928, l’éditeur semble se détacher de la photographie en noir et blanc au profit d’illustrations colorées au pochoir. Alors, il est nécessaire d’interroger quels rôles photographie et photographes occupent dans son projet éditorial et comment la concession du laboratoire photographique de l’Union centrale des arts décoratifs, assurée par la famille Lévy de 1907 à 1936, s’inscrit dans ses activités

"In 1879 Philadelphia manufacturer John Carbutt and New Yorker Albert Levy both had placed their dry plates on the market. The development had been long awaited by wet-plate practitioners; many new workers were lured to photography as a result of the great simplification of technique. Almost overnight, camera clubs found their membership changing. The Photographic Society of Philadelphia, once composed of "the most expert photographers and scientific men of the city,55 now included "skillful amateurs, who find in photography pleasant and healthful recreation; scientists who study the art experimentally; artists to whom the camera is a helpful tool, travelers who [make] pictorial records in all parts of the world, and professional photographers of the highest ability."In 1879 Philadelphia manufacturer John Carbutt and New Yorker Albert Levy both had placed their dry plates on the market.
