Step 1 : Introduction to the question "What was removed from Dr Pepper back in the 1950s?"
...The drink was created in the 1880s by pharmacist Charles Alderton and first served in Morrison's Old Corner Drug Store in Waco, Texas. Wade Morrison, owner of the drug store, is credited with naming the drink "Dr Pepper" after a friend of his, Dr. Charles Pepper. The period was removed from the logo in the 1950s. It may have been named after a physician, but the correct styling of the name is “Dr Pepper,” not “Dr. Pepper.” The company dropped the period from the name as part of a redesign of the corporate logo. Most sources suggest that the revamped logo was easier to read without the punctuation, and Dr Pepper was reborn.
