Americus was originally from Kentucky and lived for years living in Chicago, Illinois.[1]

In June 1902 he received a patent for the window envelope. It was first referred to as the "outlook envelope". To form the window, very thin rice paper was first used, later replaced by clear plastic. This allows the inside address to then serve as the outside address for mailing. The plastic window is also referred to as a patch.

Americus leased the patent to the Envelope Company of Springfield, Mass., which began its manufacture in July 1902.

My aunt wrote a history book of the 1900, it states that her sister Thursa Ford had a private nursing job with the man that invented the window in the evelope but says his name was a Mr Eckhardt? She was with him for 19 years, until 1973. She got this job in New York ,l gather in 1954 and moved to Florida with Mr Eckhardt, who was only expected to live no more than 6 months. Is this story of any relevence to your family? Email; [email address removed] Thanks
