Born on 13 July in the year 1913 in Mulleriyawa Colombo, Gunathilaka Bandara Senanayake was the youngest of a family of four boys.
He had his primary education at St. Joseph's College in Grandpass. Then he had his secondary education at Ananda College Colombo. Due to economic problems he gave up schooling at the age of 14.
Later he did further studies on his own. At the age of 18 he started going to the public library in Colombo which gave him the opportunity to access thousands of books. G.B. Senanayake calls the public library his own university.
Martin Wickramasinghe, then editor of the 'Dinamina' newspaper recognising G.B. Senanayake's abilities offered him a job at Lake House. For some time Senanayake worked as a professional journalist at 'Dinamina' and 'Sinhala Bauddhaya'.
Later he left Lake House and while living an unmarried life devoted his time to writing books.
G.B. Senanayake was awarded the 'Sahithya Shoori' (literary doctrine) award by the Sri Jayawardanapura University in 1985.
During the later part of his life Senanayake started losing his eyesight. Yet notwithstanding, he didn't give up writing. 'Vinividimi Andura' is a book written during that time.
G.B. Senanayake died on 16 March 1985.
