Roberta Kevelson was the #1 authority on the pragmatism theories of Charles Sanders Peirce, and an authority on Semiotics in general. A professor at Penn State and William and Mary, she wrote and published several books such as High Fives, The Inverted Pyramid, and the Law as the System of Signs. Her most famous study most likely was occured in her book; Peirce and the Mark of the Gryphon. Furthermore, she was one of the founding members of the Semiotic Society.
The late (1931-98) Kevelson (philosophy, College of William and Mary) drew from the unpublished manuscripts of American semiotician Charles S. Peirce (1839-1914) to explore how he conceived of the evolution of thought from instinct and imagination as expressed in myth, to ideas that are exchangeable units of meaning.
