METZ, John D. (Holland, Mar. 5, 1822--Dubuque, IA, July 2, 1918). In 1875 Metz received the American Institute of New York's only award for blank books. The following year at the Centennial Exhibition in Philadelphia, he received the grand medal of honor and diploma of highest merit. (1) In 1884 his business had $4,000 in its value of production. (2)

Metz received three patents for photographic albums and binders. One binder was made by securing each page of the album to metal plates. These were placed together so that a series of joints were formed. The eyes of the hinges caused spaces to be left equal to the thickness of the page. This allowed photos to be mounted on the page without the book bulging. (3)

In September, 1891 Metz, the inventor of an automatic railroad brake, was given honorary membership in the Academy of Inventors in Paris, France. (4)
