Roberta "Bobbie" Kevelson (November 4, 1931 – November 28, 1998) was an American academic and semiotician. She was an acknowledged authority on the pragmatism theories of Charles Sanders Peirce. Personal life Kevelson was born in Fall River, Massachusetts and graduated from B.M.C. Durfee High School in 1948. Although married at 17, she returned to college in the 1960s and received her PhD in semiotics from Brown University in 1978. Career During her postdoctoral time at Yale University (1979–1981), she introduced the concept of legal semiotics. She subsequently established an international cross-disciplinary center for its study in 1984: the Center for Semiotic Research in Law, Government, and Economics at the Pennsylvania State University. She had joined the philosophy faculty of the Berks Campus at Penn State in 1981, where she was awarded the AMOCO Foundation Outstanding Teaching Award in 1986. She was a visiting professor at several institutions, including The College of William & Mary, Virginia. Among her published works are High Fives, The Inverted Pyramid, The Law as the System of Signs and possibly her most significant work, Peirce and the Mark of the Gryphon. She was a founding member of the Semiotic Society of America. Works Several works are included in the Charles Sanders Peirce bibliography. Kevelson, Roberta (1986), Charles S.
