A young pharmacist by the name of Charles Alderton first invented Dr Pepper in 1885 in the city of Waco, Texas . Alderton was working in a drug store where sodas were served at a soda fountain . Alderton had begun inventing his own soda recipes and found his Dr Pepper flavors were becoming very popular . The drink that soon became Dr Pepper was originally nicknamed a "Waco" and customers would ask Alderton to shoot them a "Waco" all the time . The drink, Dr Pepper, was originally named by the owner of the drug store where Alderton worked . The owner had decided to name the drink after a close friend of his, Dr . Charles Pepper . A businessman named Robert S . Lazenby stepped in when Alderton and Morrison, the drug store owner, found it difficult to meet the rising demands of customers who loved Dr Pepper flavors . Alderton decided he didn't want to pursue the business and manufacturing of a soft drink, so he allowed Lazenby and Morrison to take over . In 1904, Morrison and Lazenby introduced Dr Pepper to the 20 million attendees of the 1904 World's Fair Exposition in St . Louis, Missouri . Interestingly, Dr Pepper is the oldest manufacturer of soft drinks in the United States . Now, of course, the soda is served and enjoyed worldwide and also in restaurant soda dispensers through the use of Dr Pepper Syrup . Great for Any Time Dr Pepper Syrup offers convenience and ease in providing soda at any time and anywhere there's a nearby soda dispenser .
