A fountain drink mixed in The Old Corner Drug Store in the 1880s was dubbed Dr Pepper. R.S. Lazenby, Waco beverage chemist and patron of the drug store, became interested in the new drink and began extensive research. In 1885, after some two years of testing, blending, and processing, the new flavor was originated and put on sale commercially. So perfect was Lazenby's work that the formula has remained basically unchanged. Museum housed in original 1906 bottling plant, now listed on the National Register of Historic Places. It features restored operating soda fountain along with other Dr Pepper memorabilia with interactive audio visual displays. Open Mon. - Sat. 10 a.m. - 4 p.m., Sun. noon - 4 p.m. at 300 S. 5th St. Admission.
