In this definitive biography about his father, Candler specifically states: " on April 14, 1888, the young druggist Asa Griggs Candler purchased a one-third interest in the formula of an almost completely unknown proprietary elixir known as Coca-Cola."[23] The deal was actually between John Pemberton's son Charley and Walker, Candler & Co. – with John Pemberton acting as cosigner for his son. For $50 down and $500 in 30 days, Walker, Candler & Co. obtained all of the one-third interest in the Coca-Cola Company that Charley held, all while Charley still held on to the name. After the April 14 deal, on April 17, 1888, one-half of the Walker/Dozier interest shares were acquired by Candler for an additional $750.[24]
