He was also invited to deliver lectures in higher mathematics at the Indian Association for the Cultivation of Science. He then took up law and appeared for the BL examination from City College under the tutorship of S.P. Sinha (later Lord Sinha). He was awarded the Tagore law gold medal three times in a row. He became a

Doctor in Law in 1994 and appointed as Tagore Law Professor in 1898. His lectures were published as The Law of Perpetuities in British India. He became a judge of the Kolkata High court in 1904 & retired in 1923, officiating for a few months as Chief Justice of Bengal in 1920. He was knighted in 1911. He believed in the liberating role of education. The

growth of racialism on the part of the British and its attendant discriminating practices entered deeply into his soul. Consequently, he felt, it was only through broad-based higher education among his countrymen that they could be cured of their sense of intellectual inferiority to the Westerners. Thus he resolved to create a modern university out of his Alma Mater, the Calcutta

University. In 1906 he was appointed Vice Chancellor of his Alma Mater. He continued the job for 8 years.When Lord Lytton became the viceroy, he was again reappointed but  Lord Lytton laid certain conditions.
Sir Asutosh turned down the offer, holding high his self-respect. This great son of Bengal passed away on May 25th, 1924 in Patna. He was a beacon of light who held the torch of education in the oppressed Indian society. Indians learnt the true sense of self respect and dignity through him.  He believed in the acceptance of Western

cultural values, but not at the cost of his own where they were truly significant and complementary. Thus he created a new outlook, which was totally Indian yet entirely free from conservatism.
