Check out this history of coffee:
First lets thank the Ethiopians for the discovery in 600AD, although they took the coffee bean a bit too seriously and worshipped it.
Fastforward to 1650 and thank Baba Budan, who snuck seeds out of Arabia into India.
But let's not forget to thank Pope Clement VIII, of 17th cent. Europe. He had been advised that coffee would be a threat to Christianity; but after having a pot, he blessed the drink and called it "a Christian beverage". Bless you, Pope Clement!
But I really want to thank the great Dorothy Jones for obtaining the first license to sell coffee in the colonies. It was in coffeehouses, where the Boston Tea Party was planned, where the Declaration of Independence was read for the first time, and where the first Continental Congress was born. Brilliant woman, Dorthy Jones!
