Fred Braue was the pioneer in using a concealed sidejog to delay the control of one or more cards. See More Card Manipulations, No. 1, 1938, p. 47.

This predates Ed Marlo's claims in Control Systems, 1952, p. 87. Also note Marlo's Delayed Fan Control, ibid., p. 83, in which three steps are used to preserve the locations of three cards while fanning the deck. This predates the recording of this technique used for just one card in Vernon's Ultimate Secrets of Card Magic, 1969, p. 128. Marlo didn't record this control method for just a single card.
