Dr. R.C. Tyagi was a distinguished physicist whose journey spanned Meerut, Hull University, NASA, IIT Delhi, and India’s defense research institutions. Known for his pioneering work in infrared missile‑detection technology and his rare blend of scientific rigor and musical insight, he lived a life defined by integrity, courage, and service. After returning from NASA at the request of Prime Minister Indira Gandhi, he fought a decades‑long battle against corruption — and won in the Supreme Court. His ancestral home in Meerut now serves as the Prof. R.C. Tyagi Scientific & Cultural Research Center, a living tribute to his belief that education, values, and culture can transform generations.
