The Meteoric rise and fall of Kathodion Bronze Works

From ads that ran in the New York Times, Century Review, and The Literary Digest,

as early as 1914,  Kathodion Bronze Works,  from their location at 501 Fifth Avenue in New York, was selling a high-end line of  Artbronz Products distinctive gifts and decorative household items which included book rocks, boudoir lamps, ashtrays, paper weights and statuary.

In 1915, the small concern fell victim to one of Wall Street’s most spectacular stock manipulation “get-rich-quick” schemes of the era.*    By 1918 Kathodion filed for bankruptcy.


Before World War I, they were hitched to the boom in automobile stocks by entering into a five-year contract to manufacture ten million tire stems annually.  Their stock was trading at $2.50 a share when Wall Street’s “pirates of promotion”*– C.R.Bergmann and Co. promoted the contract on the Wall Street Curb. Their stock advanced to $23 a share, although few tire stems were actually produced.


World War I created a perfect opportunity for The Bergmann Co. to promote talk of ammunition contracts. Kathodion’s stock skyrocketed to $68 a share.  Kathodion, believing they could secure profitable foreign contracts, bought  an abandoned warehouse in Nyack, New York and installed machinery for the production of ammunition.   Plans were laid to increase the company’s capital from $500,000 to $20,000,000 by selling more stock, earning millions in profits for the Bergmann outfit.


The foreign contracts never materialized.  Kathodion was swindled with its contracts for the purchase of munition-making machinery.  The stock passed completely off the Curb market and Kathodion filed for bankruptcy, leaving its investors with nothing more than  beautifully engraved stock certificates.
