ANSWER:  
This is a story about clashing egos that  led to the naming of a product.  It goes back to the 
formation of Gedney Electric by Malcom W Herron.  The company name itself came from a 
street near his home called Gedney Way in Mamaroneck NY and the office was in Radio 
City Music Hall. 

Appleton Electric manufactured a successful line of liquidtight fittings under the ST-50 part 
number series.  Arthur Appleton asked/told Malcom Herron not get in the Liquid Tight fitting 
business.   Malcom ignored Arthur and designed his own fitting.  To gain immediate market 
acceptance, he marketed it under the same part number.  Appleton sued and won forcing 
Gedney to change their part number.  Thus the response to the Appleton suit was Gedney 
saying 4Q as a printable and long lasting expletive.
