The document provides a historical timeline of notable linguists, beginning with analyses of ancient Sumerian and Sanskrit grammarian Panini. It then discusses contributions of Greek philosophers like Socrates and Plato, as well as the Romans' focus on Latin morphology. The timeline continues through medieval speculative grammarians, Renaissance scholars like Chrysoloras, and 19th century philologists like Grimm and Bopp. Key 20th century figures presented include Saussure, Jakobson, Sapir, Whorf, Chomsky, and Lakoff. Their work established foundations in fields like structural linguistics, cognitive linguistics, and the Sapir-Whorf hypothesis.
