As his request for a raise of Rs. 2 a month was turned down, he quit the factory for good. "It was a turning point in my life. I walked out of the factory and started making matches on my own. I sold them on the streets," were his own words about his experience.

In the 1930s, matches were imported from Burma, Sweden and Japan. These were machine-made and had a polished finish. Mr. Chelladurai's matches were handmade and still, he competed with the foreign companies.

Eventually, he turned his attention to fireworks. In the beginning, he imported raw materials from other countries and conducted various trials. Later, he surged ahead in the field of pyrotechnics and broke the monopoly of countries like China and Taiwan.

Today, the company he founded employs about 9000 workers and is the technical adviser to the Indian Army, besides supplying them with practice bombs, hand grenades and so on. The company also supplies fog signals to Indian Railways and provides guidance to the Sri Lankan government. In addition to fireworks, he was associated with a number of industries. His company, Bell Pins, manufactures several wire based products like pins, clips, staplers and so on. Today, pins and other products sold under the Bell banner are a household name in India.

Mr. Chelladurai's contributions were recognized far and wide, and he was the recipient of several locally and nationally acclaimed awards and certifications, which are listed below:
