Dr Pepper (now without the period for “Dr.”) is a soft drink that began in Waco, Texas in 1885. “Good for life!” is one of Dr Pepper’s longest-used slogans, from 1923 until the 1950s.
   
 
Dr. Pepper
Charles C. Alderton worked as a pharmacist for W. B. Morrison in Morrison’s Old Corner Drug Store in Waco, Texas.  In 1885, he invented a new drink formula which became very popular with Morrison’s customers.  Morrison bought the formula from the young man and named it “Dr. Pepper”, possibly after Dr. Charles Pepper, a former employer of Morrison’s in Virginia.  Morrison then sold the formula to Robert S. Lazenby.

Dr. Pepper has had several distinctive changes in trademarks.  Around 1905, the term “Phos-Ferrates” was dropped in favor of a Dr. Pepper logo with a tail sweeping back from the final “r” enclosing the words, “King of Beverages”.  The company changed the lettering style in 1913 and included the words, “Liquid Sunshine”.  Following the 1923 reorganization, Dr. Pepper bottles were standardized for the first time and replaced the old slogans with “Good for Life” in the tail.
