This chapter presents an introduction to David Kaplan. Topics covered include the influence of Church, Carnap, and Montague, from whom Kaplan got the eye for elegant formal codifications; Kaplan's admiration and adoption of the work of the German logician Gottlob Frege as the ground philosophical framework; his most influential work, _Demonstratives_, which presented his pioneering account of “direct reference” and what is essentially a two‐stage theory of meaning; and his separation of semantics and modal metaphysics.

The first page of Frege’s classic “Uber Sinn und Bedeutung” sets for more than a hundred years now the agenda for much of semantics and the philosophy of mind. It presents a purported puzzle whose solution is said to call upon the “entities” of semantics (meanings) and psychological explanation (Psychological states, beliefs, concepts). The paper separates three separate alleged puzzles that can be read into Frege’s data. It then argues that none are genuine puzzles. In turn, much of the Frege-driven theoretical development, motivated as an inevitable “solution”, is thrown into doubt.
