Peter Hall spent the years 1980 to 1992 on the faculty of the University of California at Berkeley. He arrived at a moment when a group of progressive young faculty and graduate students were collaborating on the development of new ways of analyzing and planning urban and regional development. Peter was a trusted friend and mentor to this group. This paper describes the work of what we called the Western Urban Regional Collective and links it to Peterís intellectual evolution. We focus on four key pillars: urban/regional development, inclusiveness, sustainability and innovation. After Peter returned to London in 1992, he remained closely involved with these themes and many of the same people. He co-founded Global Urban Development (GUD) in 2001 as an international non-profi t research and policy organization that adopted these four pillars as its core mission. GUDís strategic policy and action framework Ė Metropolitan Economic Strategy, Sustainable Innovation, and Inclusive Prosperity Ė is based on ideas originally developed at Berkeley in the 1970s and 1980s. We describe the activities of GUD to bring this aspect of Peterís work to a broader audience.
