A older gentleman with a bushy mustache poses for his photograph at the Van Dyke Studio in New York City. Printing on the front of the cabinet card indicates that the owner and operator of the studio was Miss Adele Becker. A female owner of a photography studio was a bit unusual during the cabinet card era but the cabinet card gallery has developed a collection of cabinet cards produced by female photographers. Click on the category “Female Photographers”. In regard to Miss Becker, research yielded little information about her life or career. It is likely she bought the studio from Mr. Van Dyke.

Girl power !
I too have a cabinet card by Adele Becker. It is a portrait of my great-grandfather, taken at the Van Dyke Studio sometime in the late 1800s. Your blog helped to shed light on this image that I have studied for years. Thanks you
