In the bustling heart of Madras (now Chennai), where the humid air carried the scent of filter coffee and temple flowers, a young Natesan Rangabashyam once gazed at the sky and dreamed of flying. Born on 5 November 1933 to Dr. Natesan, a gentle general practitioner, and Vittobai, he grew up watching his father tend to patients with quiet patience. Planes fascinated him. “I want to soar above the clouds,” he told his friends at Loyola College, where he studied natural sciences. But destiny had other plans.

One day, after watching a skilled surgeon at work, something shifted. “The human body is more complex than any machine,” he confided to a classmate. “If I can repair it, I can help people stay on the ground—and live fully.” He switched to medicine at Madras Medical College, earning his MBBS in 1957. The operating theatre became his new sky.

Seeking the best training, he sailed to the United Kingdom. Under mentors like Ivor Lewis and Owen Daniels, he immersed himself in gastroenterological surgery. In 1963 he secured his FRCS from the Royal College of Surgeons of Edinburgh. Hospitals in Wales, Scotland, and London sharpened his hands and mind. Yet India called him home.

In 1964 he returned and joined Thanjavur Medical College as an honorary surgeon. The temple town welcomed a pioneer. There he set up a dedicated gastrointestinal clinic, introduced laparoscopy, performed selective vagotomy, and carried out his first hepatic resection. “Why should patients travel far for specialised care?” he asked his colleagues. “We can build excellence right here.”

Five years later he moved to Stanley Medical College in Chennai, then in 1975 to Madras Medical College and Government General Hospital. That year he founded India’s first dedicated Department of Surgical Gastroenterology—and later introduced the country’s first MCh course in the specialty. He established an ostomy department, started the first enterostomal therapy diploma for nurses, brought surgical staplers into Indian practice, and advanced laparostomies and hepatobiliary surgery. Students remembered how he would return from an overseas conference at dawn and still appear for an undergraduate clinic an hour later.

“Surgery is not just technique,” he would tell his postgraduates in the ante-room of Operation Theatre 4. “It is listening to the patient, understanding the disease in our tropical context, and training the next generation so the knowledge multiplies.” He trained generations of surgeons, examined candidates in India and abroad, and helped bring the FRCS examination to Indian soil. He served as honorary surgeon to President R. Venkataraman and as a consultant at the Armed Forces Medical College.

Recognition followed his quiet labour. He received the Dr. B.C. Roy Award twice—the highest medical honour in India. In 2002 the nation conferred the Padma Bhushan. His name was inscribed on the Wall of Honour at the Royal Society of Medicine in Edinburgh. The Government of Tamil Nadu named him a Living Legend. Fellowships from the American College of Surgeons, the International College of Surgeons, and many others followed.

At home, he was husband to Chitralekha and father to Omprakash and Mahalakshmi. Colleagues called him “NR”—a name spoken with respect and affection. He published, lectured internationally, and contributed chapters to major textbooks, yet never lost the teacher’s hunger to share.

On 14 July 2013, Natesan Rangabashyam passed away peacefully in his sleep in Chennai, aged 79. The department he built continued. The surgeons he trained carried his standards forward. And in operating theatres across India, when a complex gastrointestinal case is approached with both skill and humanity, the spirit of the man who once dreamed of flying still guides the hands that heal.

His life was not a sudden ascent but a steady climb—turning personal ambition into a specialty that did not exist before him, so that countless patients could walk away from the table and live.
