LANGSON MFG. CO. was founded by Inventor Otto A. Langos and was located in Chicago, IL from 1932-1974. The address of their final and largest manufacturing plant was  4200 W. Wrightwood Ave., Chicago 39, ILL.  Other known LMCO Chicago addresses as they grew and moved through the years were  356 W. Huron Street (c. 1933),  878-880 Lill Ave., and 429 W. Surerior Street (c.1937).      

 

The first US Patent issued to inventor Otto A. Langos was in 1904 when he was not yet a US citizen, and the full story behind this patent may never be known.  How it's possible that a music teacher of the Zither from Hungary can immigrate to the US with almost no money and knowing little English but quickly accomplish this expensive and improbable feat is a mystery.  Against the odds, Otto may have made money from this first patent to help jump- start his new journey in America,  where he did end up inventing his way into living the 'American Dream'.  

 

Otto would go on to be a very successful inventor and business owner with 24 issued US Patents across an unusually wide scope of fields including: Railroad track swith, paper buster toys, toy cars, hair curling iron, flashligh switch, food cooker, pipe crimping machine, and many more. Otto's influence also reached out to his sons who had several patents of their own and incredibly extended all the way out to his great grandson who was issued US Patents 100 years after his first.
