Hardy-Heck-Moore, Inc. collection

Hardy-Heck-Moore (now HHM & Associates) is a historic preservation consulting firm based in Austin, Texas. Daniel Hardy (1950—1993), Marlene Heck, and David Moore formed Hardy-Heck-Moore in 1982 after working together at the Texas Historical Commission in the late 1970s and early 1980s. The company specializes in "cultural resource management, historic architectural survey and research, historic tax credit assistance and historic landmark designations throughout all 50 states for federal, state, and local governments, as well as non-profit groups and private clients." Historian Terri Myers joined Hardy-Heck-Moore in 1990, and the company operated as Hardy Heck Moore & Myers from 1995 until 2001 when Myers left. As of 2018, the company operates as HHM & Associates.

Since 1983 Hardy-Heck-Moore has conducted over 700 architectural documentation, research, and landmark evaluation projects across the United States resulting in the listing of over 8,000 historic sites and over 70 historic districts to the National Register of Historic Places (NRHP), and over 100 historic sites to the Historic American Buildings Survey (HABS) and Historic American Engineering Record (HAER). Hardy-Heck-Moore is noted for helping to develop innovative historical survey practices in the 1980s and 1990s that improved the documentation of underrepresented historic communities and building types, especially vernacular building types, using new technologies such as computerized databases. In the 1980s and 1990s, the company was especially prolific in the development of Multiple-Property Submission (MPS) nominations, which facilitated the listing of thousands of historic places to the NRHP using a batch nomination process. The 1987 project Historic Resources of McKinney was the first nomination nationwide to use the MPS format, and the 1988 MPS project Historic Resources of Cuero received the Texas Award for Historic Preservation from the Texas Historical Commission. Further, in 2005, Hardy-Heck-Moore received the Naval Facilities Engineering Command (NAVFAC) Commander's Certificate of Commendation for the Preservation Analysis Reports of selected buildings in the Naval Air Station (NAS) Pensacola National Historic Landmark, which had been extensively damaged from Hurricane Ivan in September 2004.

Marlene Elizabeth Heck was born on August 25, 1952 in Wilkes-Barre, PA and grew up in Bryan-College Station, Texas. She received a bachelor's degree in History from the University of Texas at Austin in 1973. Heck received a Master of Architectural History in 1977 from the University of Virginia. She worked at the Texas Historical Commission 1977-1978 and left to take a visiting position teaching architectural history at Texas A&M University's School of Architecture. Heck then returned to Virginia to work at the Virginia Historic Landmarks Commission until she left to pursue a doctorate in American Studies at the University of Pennsylvania. While working on her doctoral studies, Heck was asked by Daniel Hardy and David Moore in 1982 to join them in co-founding Hardy-Heck-Moore; she remained with the firm until 2015. After receiving her doctorate in 1988, Heck returned to Texas A&M's School of Architecture for two years. She then taught architectural history and American Studies at Dartmouth College for thirty years before retiring as a Senior Lecturer Emeritus in 2021.
