Pattipati Ramaiah Naidu (a.k.a. Dr. Ramaiah Naidu) (June 1904 - June 6, 1991) was a pioneering Indian nuclear Physicist, Medical Scientist and Radiologist who helped to establish the foundations of medical physics. He is better known for working under double Nobel Laureate, Marie Curie, for his post-doctoral thesis in Paris, France and pioneer in establishing up Radiology laboratory in India in 1938.

Naidu was born at Madanapalli, in the Chittoor district of Andhra Pradesh state in India in June 1904. In an early age he left home to join Aurobindo Ghosh's fledging ashram in Puducherry. From there he went to Santiniketan where he taught Mathematics. In 1923 he graduated with honours in B. Sc. from Banaras Hindu University.

After refusing a scholarship grant from England, he went to Paris to complete his M. Sc. Degree from University of Paris in 1929. He later wrote to Marie Curie, Polish physicist and chemist based in Paris, famous for her pioneering research on radioactivity expressing his desire to work with her, and was accepted into the Sorbonne where he completed his Doctor of Science in 1933. Here he worked with Marie Curie of Radium Institute, Paris for his Doctoral thesis under four years Curie-Carnegie Research Fellowship. The thesis covered ionization curve of alpha rays in pure gases including Krypton and Xenon and published his first research papers in French in the Journal of Physics and Radium, Paris in 1934. Upon Curie's death in 1934 Ramaiah Naidu was running her laboratory for a while.

Later he moved to England to work under the English experimental physicist Prof. P. M. S. Patrick Blackett, in London University for his Ph. D. thesis which was awarded to him in 1936. In 1936, Tata Trust, Mumbai offered Ramaih Naidu the post of Chief Physicist at Tata Memorial Hospital, Bombay and sought his services to help establish India's first Radon production facility for treatment in Cancer Management. In 1936, Ramaiah Naidu spent another two years at the New York's Sloan Kettering Memorial Hospital, now known as Memorial Sloan–Kettering Cancer Center under G. Failla where he installed Radium Extraction unit for radon production.
