William McKenzie “Mack” Woodward, a respected architectural historian at the Rhode Island Historical Preservation and Heritage Commission (RIHPHC), passed away in 2026. Known for his deep knowledge and passion for Providence’s architectural heritage, Mack was a key figure in historic preservation for nearly four decades. He co-chaired the Providence Preservation Society’s Markers Committee and authored The Guide to Providence Architecture, a seminal work digitized in 2015 and widely used by scholars and the public.

Starting his career in the 1970s alongside colleague Ted Sanderson, Mack helped inventory and document Rhode Island’s historic buildings under the leadership of preservation advocate Antoinette Downing. His early surveys, including the 1980 study of Providence’s Smith Hill neighborhood, highlighted often-overlooked vernacular architecture such as workers’ cottages and triple-decker houses, elevating their importance in the city’s architectural narrative. Mack also played a crucial role in documenting Providence’s historic downtown business district, advocating for its recognition on the National Register of Historic Places despite local concerns about economic impact.

Mack’s encyclopedic architectural knowledge and dedication made him a trusted resource and beloved figure in Rhode Island’s preservation community. His work continues to influence and inspire new generations committed to safeguarding Providence’s architectural legacy.
