  In 1952, David Bohm proposed a deterministic, ‘hidden variables’ quantum theory that reproduces all the observable predictions of orthodox quantum mechanics (see Bohm 1952, Bohm, Schiller and Tiomno 1955, Bell 1982, Dewdney, Holland and Kyprianidis 1987, Dürr, Goldstein and Zanghì 1992a, 1997, Albert 1992, Valentini 1992, Bohm and Hiley 1993, Holland 1993, Cushing 1994, and Cushing, Fine and Goldstein 1996; for an entry level review, see the entry on Bohmian mechanics and Albert 1992, chapter 5).
