The man who invented Coca-Cola was not a native Atlanta, but on the day of his funeral every drugstore in town shut up the shop in honor of him. He was John Styth Pemberton, born in 1833 in Knoxville, Georgia, eighty miles away. Pemberton was a chemist, sometimes known as Doctor, who, during the Civil War, became an officer and led a cavalry troop. He settled in Atlanta in 1869, and soon began making such patent medicines as Triplex Liver Pills and Globe of Flower Cough Syrup.

In 1885, he registered a trademark for something called French Wine Coca-Ideal Nerve and Tonic Stimulant. A few months later, he formed the Pemberton Chemical Company, and hired an accountant named Frank M. Robinson, who had not only a good head for figures, but, attached to it, so unique a nose that he could judge the ingredients of a batch of syrup merely by sniffing it.

In 1886 --- a year in which, as contemporary Coca-Cola officials like to point out, the English writer Conan Doyle made Sherlock Holmes known publicly and France found the truth about the Statue of Liberty --- Pemberton invented a syrup that he called Coca-Cola. It was a change of his French Wine Coca. He had taken out the wine and added a bit of caffeine, and, when the end product tasted awful, had thrown in some cola nut oil and a few other oils, mixing the mixture in a three-legged iron pot in his back yard and swishing it around with an oar.

He distributed it to soda fountains in used beer bottles, and Robinson, with his elegant account’s script, instantly designed a label, on which "Coca-Cola" was written in the style which is still employed. Pemberton looked upon his mixture less as a drink than as a headache cure.

One morning in 1886, a man suffering from a headache dragged himself into an Atlanta drugstore and asked for a bottle of Coca-Cola. According to usual practice, druggists should pour a teaspoonful of syrup into a glass of water, but at that time, the man on duty was too lazy to walk to the fresh-water tap. Instead, he mixed the syrup with some soda water, which was closer at hand. After drinking it, the suffering customer cheered up almost at once, and word quickly spread that the best Coca-Cola was a fizzy (冒泡泡的)one.
