Dr Pepper has been on supermarket shelves for nearly 140 years, yet many fans are only now discovering the surprising theory behind its famous name. The beverage was created by American pharmacist Charles Alderton in Waco, Texas, in 1885. Originally called "Waco," the drink was renamed by store owner Wade Morrison, who began selling it in his pharmacy. It quickly became a hit, but the origin of the name remains a mystery.
The Romantic Theory
One romantic theory has become far more famous than the rest. According to Today You Should Know, "This is the most widely cited theory, even appearing on Dr Pepper's corporate website." The story goes that Morrison was in love with the daughter of Dr Charles T. Pepper, his former employer in Virginia, and named the drink after him to impress his would-be father-in-law.
However, the Dr Pepper Museum says there is no real evidence to support this claim. The museum points out that Dr Pepper's daughter would have been no older than 11 at the time, making the theory highly unlikely. The museum explains: "To test his new drink, Alderton first offered it to store owner Morrison, who also found it to his liking. After repeated sample testing by the two, Alderton was ready to offer his new drink to some of the fountain customers. They liked it as well. Other patrons at Morrison's soda fountain soon learned of Alderton's new drink and began ordering it by asking him to shoot them a 'Waco.' Morrison is credited with naming the drink 'Dr Pepper' (the period was dropped in the 1950s). Unfortunately, the origin of the name is unclear. The museum has collected over a dozen different stories explaining how the drink became known as Dr Pepper."
Fan Reactions and Other Theories
Despite the lack of evidence, many fans still believe the romantic tale. One person said: "A pharmacist named Charles Alderton created Dr Pepper in 1885. Alderton worked at a drugstore in Waco, Texas, owned by Wade Morrison. Legend has it that Morrison named it 'Dr Pepper' after the father of a young girl he was once in love with." Another added: "When the soda inventor was young, he worked for a pharmacist called Dr Pepper. Dr Pepper had a young daughter who the inventor fancied, but Dr Pepper didn't want him to have anything to do with her. The pharmacy was also where he first started experimenting with soda making."
Other theories suggest the drink was named after another doctor called Pepper, chosen as a marketing tactic, or intended as a gesture of thanks. The true origin remains unconfirmed.
Recent Developments
Despite being around for 140 years, Dr Pepper has kept fans excited with new flavors. In February 2026, the brand launched Dr Pepper Cream Swirl, a limited-edition flavor that blends the classic 23-flavor recipe with a smooth, silky vanilla cream finish. It is widely available across the UK in grocery stores like Sainsbury's and local convenience shops, and will remain on shelves until February 2027.
