Kalipada Basu, also known as K. P. Basu (1865 – 1914), was a renowned Bengali mathematician and science teacher. He was the founder of K. P. Basu Publishing Company.
K. P. Basu was born in Harishankarpur village of Jhenaidah district in Bangladesh. His father's name was Mahimacharan Basu, who was a vendor at the local Harishankarpur Registry Office (at that time the Jhenaidah Registry Office was located in Harishankarpur village).
After finishing his studies at the village school, he was admitted to Lord Ripon College, passed the entrance examination from there, and obtained a higher degree in mathematics from the University of Calcutta.
He brought many strange and complex rules of algebra into simple formulas, and many formulas in use today are his innovations. Through his single-minded devotion, books such as Algebra Made Easy, Modern Geometry and Intermediate Solid Geometry were composed. Printing technology was not so developed in his time. To fill this gap, he established the K. P. Basu Publishing Company in Calcutta, which still exists today at 42 Bidhan Sarani, Calcutta. He was a person fond of music and theatre. During the autumn Durga festival he would sit among the common spectators and enjoy the performances.
After completing his studies, he joined Dhaka College in 1892 as a teacher of mathematics and worked there until his death.
He composed quite a few textbooks of mathematics:
- Algebra Made Easy
- Modern Geometry
- Intermediate Solid Geometry
By dint of talent, perseverance and labour, he overcame his hereditary poverty and achieved eminence, and became the owner of much wealth. In 1907 he built a palatial building in his native village. He died in Dhaka in 1914 of pernicious malaria fever. When his dead body arrived at Jhenaidah, all the offices and courts of Jhenaidah were closed. Grieving thousands of people gathered on the bank of the Nabaganga river to pay him their last respects. A road in Jhenaidah town has been named 'K. P. Basu Road' after him.
