Envelopes History

Did you know that until 1840, all envelopes where handmade? It was in that year that a man named George Wilson of the UK created a method where a number of envelope patterns were printed onto a sheet reducing the amount of waste produced when making them individually. Later in 1845, Edwin Hill & Warren de la Rue created a technique which involved a steam powered machine. This machine not only cut out the shapes from these sheets, but also creased and folded them too. The pair were granted a British patent for the first envelope-making machine.
