such as that offered by the Heritage Conservation Network, that provide hands-on training on a wide variety of techniques from documentation to pointing with lime mortar. Legacy Peterson's legacy can be summed up by his tireless efforts to establish historic preservation as a professional endeavor. He made essential contributions to how old buildings should be documented and architects trained. Every holder of a degree in historic preservation should also credit Peterson for the origins of their education. Lastly, Peterson established a scholarly basis for building interventions. No longer was an antiquarian aesthetic ethic acceptable for historic preservation; all work had to be documented and changes well substantiated with historical records. Peterson served as the first president of the Association for Preservation Technology International. A 2006 issue of its APT Bulletin featured remembrances by his colleagues.
