Maria was the second wife of Jean Jacoby. She was a native German from Hessen and met him shortly after World War I in Frankfurt, where he had emigrated from Strasbourg. She later immigrated to the United States after the death of her husband in 1936. There she re-married to become Maria Lamkin. She participated “hors concours” in the 1936 art competitions with her work Girl in Shot Put, which was a wall hanging on silk for club rooms. In 1936 there was no category for Applied Arts (only Applied Graphics). The only known image of her tapestry can be seen in a photo of the respective exhibition room of the Berlin art competitions. The size of her work may have been roughly 1 x 2 meters.
