Sir Jagadish Chandra Bose is remembered as one of India’s greatest scientists, known across the world for his path-breaking work in physics, biology, and botany. His life journey, full of dedication, curiosity, and discipline, continues to inspire students, researchers, and science lovers. This PDF book summary of Sir Jagadish Chandra Bose’s biography offers an easy and clear explanation of his early life, education, major inventions, scientific contributions, and lasting legacy.

Early Life and Background

Jagadish Chandra Bose was born on 30 November 1858 in Mymensingh (now in Bangladesh). His father, Bhagawan Chandra Bose, was a respected government officer, and his mother, Bama Sundari Devi, provided him with a strong cultural and moral upbringing. From childhood, Bose was encouraged to study both Indian and Western traditions. His father admitted him to a local village school so he could grow up connected to Indian culture and values.

Bose was naturally curious. He loved reading stories from ancient Indian texts, listening to tales of bravery, and exploring nature around him. This early connection with plants and the environment later played a major role in shaping his scientific research.

Education and Inspiration

After finishing his basic schooling, Bose moved to Kolkata for higher studies at St. Xavier’s School and later St. Xavier’s College. Here, he came under the guidance of Father Lafont, a Jesuit teacher known as the Father of Modern Science in India. Father Lafont noticed Bose’s sharp mind and encouraged him to pursue research in science.

Later, Bose travelled to England to study medicine. However, due to health issues, he shifted his focus to natural sciences. He completed his studies at Cambridge University under some of the best scientists of that time, including Lord Rayleigh. His time in England built a strong foundation in scientific research.

Scientific Career in India

On returning to India, Bose joined Presidency College, Kolkata, as a professor of physics. But he faced discrimination under British rule. He was initially paid a lower salary than his British colleagues. Instead of giving up, he continued his work with even greater determination. His outstanding research soon forced the administration to give him full pay and permanent status.

Bose began exploring the world of electromagnetic waves. At a time when wireless communication was still new, he conducted experiments on how radio waves travel. Many researchers believe Bose was the first to create a device similar to what we today call the “radio detector”. His work laid the groundwork for modern wireless communication.

Inventions and Scientific Contributions

Sir J. C. Bose’s contributions extend across multiple fields:

1. Microwave and Radio Wave Experiments

Bose demonstrated the use of millimetre-length electromagnetic waves as early as 1895—almost the same period Guglielmo Marconi was working on wireless communication. Although Bose did not patent his device immediately, he is now globally respected as one of the pioneers of wireless technology.

2. Plant Physiology Research

One of his most unique and popular contributions is in the field of plant science. Bose proved scientifically that plants also feel pain, joy, and other stimuli. He created an instrument called the Crescograph, which could measure the growth of plants and their reactions to external conditions. This discovery amazed the entire world and opened a new chapter in botany.

3. Invention of the Coherer

Bose improved the design of the coherer, a device used to detect radio waves. His version was more sensitive and efficient, which later influenced the development of wireless communication instruments.

Writing, Literature, and Multitalented Personality

Apart from being a scientist, Bose was also an excellent writer. His book Niruddesher Kahini is considered the first Bengali science fiction story. He believed that science and literature are not separate, but different ways of understanding the world.

Recognition and Awards

For his incredible contributions, Bose received many honours:

• Knighted by the British Government in 1917

• Elected Fellow of the Royal Society (FRS)

• Honoured by universities across India and the world

But more than awards, Bose valued the progress of science and education in India.

Establishment of Bose Institute

In 1917, he founded the Bose Institute in Kolkata. It became one of India’s earliest research centres devoted to interdisciplinary scientific research. Even today, the institute carries forward his vision of combining physics, botany, and biotechnology.

Legacy and Inspiration

Sir Jagadish Chandra Bose’s life teaches us the power of determination, humility, and curiosity. He never chased fame or patents. Instead, he believed that scientific knowledge should be shared freely for the benefit of society.

His biography, now available in PDF summaries for students, is widely read across India. It offers motivation for young minds who want to become scientists, researchers, teachers, or innovators.

Conclusion

The biography of Sir Jagadish Chandra Bose is not just a story of a scientist—it is the story of a man who broke barriers, challenged colonial injustice, and changed the world with his ideas. This PDF book summary captures his journey in simple Indian English so that every student can understand and learn from his life.

Sir J. C. Bose remains a symbol of India’s scientific spirit and a guiding light for future generations.
