Charley Pemberton, an alcoholic and opium addict, unnerved Asa Candler more than anyone else. Candler is said to have quickly maneuvered to purchase the exclusive rights to the name "Coca-Cola" from Pemberton's son Charley immediately after he learned of Dr. Pemberton's death. One of several stories states that Candler approached Charley's mother at John Pemberton's funeral and offered her $300 in cash for the title to the name.
