[1] In his 1996 reference book Art Deco Sculpture & Metalware, Alfred W. Edward presented eleven colour plates of Rohac's work, captioned as bearing the "Rena Rosenthal touchmark."
This "touchmark" was actually the maker's mark of Richard Rohac (mirror image capital Rs inside of a box), which Edward illustrated on page 67 of his book.
[5] Rohac began and completed his apprenticeship with Werkstätte Hagenauer Wien in Vienna as a teenager, and stayed with the workshop another nine years before opening his own metalwork business in 1932.
When a market emerged again for decorative objects, Rohac turned his talents to the design and production of busts and sculptures, as well as everything from desk and smoking accessories to corkscrews to bookends to pretzel holders to candlesticks.
[7] Rohac's work was featured in an American newsreel on Austrian arts and crafts; one of his African busts was a state gift from Austria to the president of Mexico.
