**THE DOCTOR OF THE REVOLUTION**
*The Untold Story of Gaya Prasad Katiyar—The Man Who Masked India’s Armed Struggle Behind a Healer’s Coat*

—

To the British authorities, he was Dr. B.S. Nigam, an unassuming physician running quiet clinics in the dusty alleys of Ferozepur and Saharanpur. To Chandrashekhar Azad, Bhagat Singh, and Shivaram Rajguru, he was their most vital operational lifeline: **Dr. Gaya Prasad Katiyar**.

While the charismatic vanguard of the Hindustan Socialist Republican Association (HSRA) struck fiery blows against the British Empire, it was Dr. Gaya Prasad who engineered the clandestine machinery that made it all possible. Behind the scent of medicinal tinctures, patient charts, and diagnostic instruments, he operated the underground bomb factories and safe havens that fueled India’s most daring anti-colonial actions.

When the colonial net finally closed around the Saharanpur laboratory in 1929, Dr. Gaya Prasad did not break. Handcuffed in the dock of the historic Lahore Conspiracy Case, he turned the courtroom into a revolutionary battleground. Behind iron bars, he endured the agony of forced-feeding during the legendary 63-day hunger strike that shook the British Raj. Banished to the living hell of Cellular Jail (*Kalapani*) in the remote Andamans, he defied the lash, the oil mills, and systemic torture through an astonishing **seventeen consecutive years of imprisonment**.

Packed with historical rigor, unyielding courage, and the untold logistics of India’s armed freedom struggle, this definitive biography uncovers the life of a patriot who surrendered his youth, his home, and his freedom so a nation could be born.

**Discover the gripping, true story of the healer who took up arms, outsmarted the British Criminal Investigation Department, and stood unbroken through seventeen years in the dark heart of imperial tyranny.**
