Duncan Campbell has worked in historic rehabilitation and restoration since 1974, when he began his career as a carpenter and a building contractor. After graduate studies at Columbia University, he co-founded Preservation Development, Inc., a private historic preservation consulting firm. As president of the firm, he directed a broad array of consulting work including federal and state historic tax credit eligible development projects, National Register Nominations, Historic Structure Reports and Preservation Planning. His firm has managed many of Bloomington's historic buildings redevelopment projects.
Campbell has served on Bloomington's Historic Preservation Commission and has been an active board member of Bloomington Restorations, and Executive Board Member of Historic Landmarks Foundation of Indiana. He recently retired as an associate professor of Architecture and Director of the Graduate Program in Historic Preservation at Ball State University's College of Architecture and Planning, and was Executive Director of Ball State's Center for Historic Preservation. He currently serves on the Bloomington Historic Preservation Preservation Commission, and chairs the Monroe County Historic Preservation Review Board. His writings include the award-winning book Indiana Barns, with Marsha Williamson-Mohr. In his retirement, Campbell is an avid organic produce gardener, a hobby that puts his restored historic barn to good use.
