Richard Montague (1930–1971) is known as a founding figure of natural language semantics, i.e., the formal study of the semantics of natural languages by means of tools from mathematical logic. Less well known is that Montague maintained a strongly skeptical view on the possibility of a systematic logico-philosophical analysis of natural language for most of his short life, adhering to the then-common belief that natural languages are fundamentally different from the languages of logic. Completely unknown, until now, has been how Montague underwent a 180-degree turn in the last few years of his life, in the late 1960s, and pioneered a precise formal analysis of the syntax and semantics of fragments of English in three seminal papers that established the research framework, the methodology, and the formal tools for the new field of study. I provide a precise and documented answer to when, where, and how Montague’s intellectual turn occurred and how it relates to Montague’s previous research interests and work.
