The Evolution Of Espresso

In the early 1900s the idea of Espresso was invented by a business owner named Luigi Bezzera, who was just trying to figure out a way to get his hands on a cup of coffee without having to wait so long.  The way that he figured out this could be done was by adding more pressure to the process.  This is how the Espresso machine came to be.  He got more than he bargained for when he realized that he had created a cup of coffee with more kick, stronger taste, on top of the process that completed much more rapidly.
What he had discovered was that the fast brewing process extracted the flavor more quickly and efficiently than the traditional style of making coffee.
The espresso machine later became in more demand when the rights to it were bought by another individual named Desidero Pavoni, who was also a very successful business person and was able to market the product extremely well.  The popularity of espresso caught on quickly and we began to see espresso stands being opened throughout the U.S.  
Here are some important dates for the evolution of Espresso:
The patent for the espresso machine which consisted of a boiler and compartments for holding different sized filters was filed in 1901 by Luigi Bezzera.  This machine created espresso by forcing boiling hot water through one of the filters into a coffee cup.
Two years later, in 1903, Desiderio Pavoni purchased the patent from Bezzera and began marketing the idea of the espresso machine heavily throughout the U.S.
Production of the espresso machine was initiated in 1905 and in 1927 the craze began to spread throughout the country as the first machine to be installed was located at a placed called Regio's which was located in New York.
A newer pump was designed for the espresso machine that increased the rate at which boiling water was pumped through the coffee, creating an even more impressive result.  This took place in 1938.
A commercial sized espresso machine was produced in 1946 that would increase the amount of espresso that the ordinary machine was capable of making.
