Charlie Martin got me interested in the semantics of singular terms in discussions at Sydney University in 1966. He urged a thesis for names and demonstratives that was, in effect, like the rigidity theses to be made famous by Saul Kripke (1971, 1980) and David Kaplan (1973, 1975, 1979a, 1979b, 1988a). He also had a view of definite descriptions that was similar to the view that Donnellan was about to publish (1966, 1968). The "Fido"-Fido theory of names kept intruding into our discussions, despite our resistance.
