Mayor Robert F. Wagner Jr. first organized a preservation committee in 1961, and the following year, created the LPC. The LPC's power was greatly strengthened after the Landmarks Law was passed in April 1965, one and a half years after the destruction of Pennsylvania Station. The LPC has been involved in several prominent preservation decisions, including that of Grand Central Terminal. By 1990, the LPC was cited by David Dinkins as having preserved New York City's municipal identity and enhanced the market perception of a number of neighborhoods.
