The great men were born in different places of this world but their activities make them familiar and closer to us. Dr. Muhammad Shahidullah was one of those who contributed a lot to Bangla Language and Literature. He was the greatest scholar of Bengal. This great scholar was born on July, 1885 at 24 Pargonas in West Bengal, India. He passed his Entrance Examination in 1904 and obtained his BA degree six years later. It took him two years to complete his MA and another two years for his Bachelor of Law degree.

He later joined the University of Dhaka in 1921 as a professor of Sanskrit and Bangla. He was awarded the Doctorate degree from Sorbonne University, Paris in 1928. "Bangla Shahitter Katha", the first well-arranged history of Bangla literature, was composed by him that was published in 1953. This great scholar remained busy with his work till he became seriously ill in 1967 and was confined to bed for about two and a half years. Dr Shahidullah breathed his last on 13 July 1969 in Dhaka. We remember him with great respect and gratitude.
