BRUCE NEVIN is a linguist who has worked closely with the Pit River tribe in northeastern California since 1970, preserving their language and supporting language revitalization. He is currently completing a database of their language under a grant from the NSF/NEH Documenting Endangered Languages Program. From 1982 until 2011 he was employed as a manager and information architect, first for Bolt Beranek & Newman until 1994, and then for Cisco Systems. Since 1991 a particular focus, in collaboration with researchers from diverse fields in the Control Systems Group, has been integration of the empirical linguistics of Zellig Harris with Perceptual Control Theory, showing how the constraints on word dependencies that constitute the objective information in language are an ongoing product of collective control. He lives with his family in his ancestral home on Martha’s Vineyard.
