While studying at the Mitra Institution, he met Poet Subhash Mukhopadhyaya who went on to become his best friend. Hemanta studied in Nasiruddin Memorial High School and then in Mitra Institution. Despite opposition from his father, Hemanta could continue singing because of his mother's inspiration.

But destiny couldn't prevent him from his son's carving out a niche in music career that blossomed into a legendary status later. He never thought that he could've a successful music career. His father wasn't too satisfied with his son's penchant for music. But his mother wanted her son to become a reputed singer like Pankaj Mallik and Saigal. His father wanted him to be an Engineer and earn a lot of money through this profession. His father used to have a small profile job with which he used to manage the family. But very soon he and his family moved to Kolkatta.

He was exposed to jatras and kabigaans in his childhood that ultimately made an impact on his music career. He passed his childhood days in a village called Baharu in Jainagar where he developed a liking for music. His younger brother Amal Mukherjee was a singer and music director. He was the middle amongst his three brothers. His father's name was Kalidas Mukherjeee and mother's name was Kiran Bala Devi. Hemanta Mukherjee was born on June 16, in 1920 at Baranashi in his Maternal Uncle's abode.

If we were to find a synonymous word "All rounder" in the Cricket Term, he can be dubbed as a genuine all rounder who was not only an extremely good singer of the highest calibre, but also a good music composer in his own right. Such prolific and effervescent eulogy showered upon Hemanta is not at all unnatural given the fact that Hemanta Mukherjee revolutionized the Indian Hindi and Bengali Music post World War II and brought to the fore a millennium which got the sobriquet as "Hemanta Yug". She further commented that Hemanta Da was not only a fabulous singer, but also a great composer of unsurpassable talents and that his music was blended with the music of Rabindra Sangeet, Bengali Folk songs, the regional music elements of Assam and Bengal and Classical and Devotional Songs. Lata Mangeshkar - the melody queen and the nightingale of India commented that while listening to Hemanta Da, it would seem to her as if a saint were singing inside a Temple. Salil Chowdhury - dubbed as one of the best and the most versatile multilingual music composers of all time was often quoted as saying that if God were to sing, He would have sung the way Hemanta Da used to sing. Two of the best ever adulations showered upon Hemanta came from Salil Chowdhury and Lata Mangeshkar.
