One of America’s most recognizable soft drinks began with an unusual idea: What if you could capture the smell of a drugstore and turn it into something people would want to drink?
That’s the inspiration behind Dr Pepper, which traces its beginnings to 1885 in Waco, Texas, where a young pharmacist named Charles Alderton was experimenting with flavors at a neighborhood drugstore.
More than 140 years later, the beverage he created remains one of the country’s most recognizable soda brands. But Alderton wasn’t setting out to build a beverage empire. He was simply trying to make something that tasted as good as his workplace smelled.
How a Texas Pharmacist Invented Dr Pepper
Alderton worked at Morrison’s Old Corner Drug Store in Waco, where owner Wade Morrison operated a soda fountain that served customers looking for refreshing drinks.
According to the Dr Pepper Museum, Alderton was fascinated by the combination of fruity aromas that filled the store as different syrups were mixed and served. He began experimenting with flavors, hoping to create a drink that captured those distinctive smells.
Eventually, he developed a formula that pleased both him and Morrison. They began serving the new beverage to customers, who quickly took a liking to it.
The drink initially became known as a “Waco” because of its hometown. Customers would reportedly ask for a Waco when ordering the increasingly popular soda. The beverage was later named Dr Pepper, although exactly how it acquired that name remains a subject of debate.

Why Is It Called Dr Pepper?
Despite the familiar name, Dr Pepper wasn’t invented by a doctor. Alderton was a pharmacist, and the Dr Pepper Museum notes that there are numerous competing explanations for the drink’s unusual name.
One popular story connects it to a physician named Dr. Charles T. Pepper, although historians have not established a definitive explanation for why Morrison chose the name. Even the punctuation has changed over time. The brand originally appeared as Dr. Pepper, complete with a period, before the company dropped the punctuation in the 1950s.
The name may remain something of a mystery, but the drink’s distinctive flavor helped it stand out in an increasingly competitive soft drink market.
The Inventor of Dr Pepper Didn’t Want to Run a Soda Company
Perhaps the most surprising part of Dr Pepper’s early history is that Alderton wasn’t particularly interested in turning his invention into a business. As demand grew, he preferred to continue working as a pharmacist rather than oversee the production and distribution of the beverage.
Morrison eventually partnered with beverage businessman Robert Lazenby to expand production and bring the soda to a wider audience. The drink received additional national exposure at the 1904 World’s Fair in St. Louis, helping introduce it to consumers beyond Texas.
Over the decades, Dr Pepper became known for its distinctive blend of 23 flavors, a closely guarded formula that remains central to the brand’s identity.
How Dr Pepper Became a Multibillion-Dollar Brand
What began as an experiment behind a drugstore soda fountain eventually became part of one of the largest beverage companies in North America. In 2018, Keurig Green Mountain and Dr Pepper Snapple Group combined in a transaction valued at approximately $18.7 billion, creating Keurig Dr Pepper.
The merger brought together major coffee and beverage brands under one corporate umbrella, but Dr Pepper’s roots remain firmly tied to its Texas birthplace. The Dr Pepper Museum in Waco preserves the history of the beverage, including the people and places involved in its creation.
And while the company has changed dramatically since 1885, its origin story remains unusually simple: A pharmacist liked the way his drugstore smelled and wondered whether he could make a drink that captured it.
That experiment became Dr Pepper.
