资料题：On the day of Pemberton 's funeral the Atlanta’s closed their drugstores to honor him because（  ）。

The man who invented Coca-Cola was not a native Atlantan, but on the day of his funeral every drugstore in town testimonially shut up shop.He was John Styth Pemberton, born in 1833in Knoxville, Georgia, eighty miles away.Sometimes known as Doctor, Pemberton was a pharmacist who, during the Civil War, led a cavalry troop under General Joe Wheeler.He settled in Atlanta in 1869, and Bo0n began brewing such patent medicines as Triplex Liver Pills and Globeof Flower Cough Syrup.In 1885, he registered a trademark fox something called French Wine Coca- Ideal Nerve and Tonic Stimulant; a few months later he formed the Pemberton Chemical Company, and recruited the services of a bookkeeper named Frank M.Robinson, who not only had a good heed for figures but, attached to it, so exceptional a nose that he could audit the composition of a batch of syrup merely by sniffing it.In 1886,a year in which, as contemporary Canon officials like to point out, Canon Doyle unveiled Sherlock Homles and France unveiled the Statue of Liberty, Pemberton unveiled a syrup that he called Coca-Cola.It was a modification of his French Wine Coca.He had taken out the wine and added a pinch of caffeine, and when the end product tasted awful, had thrown in some extract of cola( or kola) nut and a few other oils,blending the mixture in a three legged iron pot in his back yard and swishing(挥动)it around with an oar.He distributed it to soda fountains in used beer bottles and Robinson, with his flowing bookkeeper's script, presently devised a label, on which“Coca-Cola" was written in the fashion that is still employed.Pemberton looked upon his concoction less as a refreshment than as a headache cure, especially for people whose throbbing temple could be traced to overindulgence.On a morning late in 1886, one such victim of the night before:dragged himself into an Atlanta drugstore and asked for a dollop(-点)of Coca-Cola.Druggist customarily stirred a teaspoonful of syrup into a glass of water, but in this instance the factotum(家务总管、杂役)on duty was too lazy to walk to the fresh-water tap, a couple of feet off.Instead, he mixed the syrup with some charged water, which was closer at hand.The suffering customer perked up almost at once,and word quickly spread that the best Coca-Cola was a fizzy one.
