F.M.F. Cazin

This article was written by fellow lamp engineer and collector Edward J. Covington, and originally appeared on his own website of biographical sketches of persons involved in the lamp industry. Following his passing in February 2017, and with kind permission of his family, Ed's words have been preserved here in the hope of maintaining access to his writings for the benefit of subsequent generations.

F.M.F. Cazin

A little-known name in incandescent lamp history is that of F. M. F. Cazin. Cazin was granted a number of patents on incandescent lamps, some of which dealt with oxide coated filaments. In 1905 he self-published a book that consisted mainly of his articles that appeared in The Electrical Age in 1901. In his book, which dealt with the incandescent lamp, he questioned the contributions of different inventors relative to his own. In particular, some works of Edison and Nernst were questioned as it regarded priority.

Apparently a company was formed in Amsterdam, New York for the manufacture and marketing of Cazin incandescent lamps. The manufacture of the lamps was started but internal dissension within the company existed and operations were discontinued before any lamps were marketed.

A picture of a Cazin lamp, as scanned from his book, is shown below.

A Cazin Lamp

Franz Cazin was born in Aachen, Germany in 1827 and emigrated to the United States in 1867. He was the eldest of ten children. In Germany Cazin apparently was a printer, bookseller and publisher. He sold his business in 1861 and built a bread factory, which failed in 1867. After Cazin came to the United States he changed his name from Franz Frederich Michael Cazin to Franz Michael Friederick Cazin. He became a mining engineer and went to Denver, Colorado in 1873, where he incorporated the Rocky Mountain Concentration Company. Apparently the Company process was described in the Engineering and Mining Journal in 1873. He also went to New Mexico where he discovered a deposit of titanium ore. In his later years he resided at 1108 Bloomfield Street, Hoboken, New Jersey. F. M. F. Cazin passed away in Upper Montclair, New Jersey on Nov 26, 1908.

The following information details the chapter titles in Cazin's book. Several chapters are simply revised reprints of the original articles. The title page of the Cazin book is also shown below.
