Progressive Aces (also known as Succession Aces) is an Ace Assembly plot usually credited to Ken Krenzel in which the first ace joins the second, then those two join the third and finally they all arrive in the last packet in sequence.
Ken Krenzel first presented the problem in Epilogue no 16, November 1972, page 146 then published one of his methods in a one-man issue of Epilogue (Special Issue no 2, page 253, 1975, Progressive Aces). Karl Fulves discussed the time frame in which Krenzel created the plot which he was showing to cardmen in New York in the early 1960s.
According to Jon Racherbaumer in When a Hat Drops (2002), Dai Vernon apparently worked out a method around 1955 and shared it with Bill Simon, who passed it on to Ed Marlo. Marlo played around with the theme but didn't publish a method until the first Marlo's Magazine (1976)
