Theodore Burr (1771-1882), was one of America’s premier bridge engineers and designers. He is famous for designing and patenting a truss/arch combination that used a traditionally framed multiple kingpost truss to which a segmented timber arch was added. This is known today as the Burr truss. The Burr truss is one of the most widespread timber bridge designs that can still be seen in covered bridges today. The Oxford Memorial Library is the former home of this illustrious covered bridge builder and the last known existing structure to be built by him.
