S.K. Nayyar, a retired assistant director, is credited with significantly developing Panchkula since the late 1980s. Initially facing a lack of basic amenities, Nayyar spearheaded resident welfare associations, advocating for district status, local courts, and improved infrastructure. His methods involved organized, peaceful demonstrations and direct engagement with political leaders, leading to achievements like securing district status and land for public facilities. Nayyar's efforts transformed Panchkula from a nascent town into a well-developed city.
