Nalini Das grew up with her sister and two cousins, which might have inspired her to write stories of four 'detective' friends as Goenda Gandalu. She had a brilliant academic career and took up teaching. When Sandesh, a well-known Bengali magazine, was relaunched she became one of the editors, a post she held until her death. The Gandalu stories first appeared in Sandesh and were very popular. Upendrakishore Ray Chowdhury (1863-1915) was a famous Bengali writer, painter, violinist, composer, technologist and entrepreneur. He was born on 10 May 1863 in a little village called Moshua in Mymensingh District in Bengal, now in Bangladesh. He spent most of his adult life in Kolkata, where he died on 20 December 1915, aged only fifty-two. He was the father of the well-known writer Sukumar Ray and grandfather of the renowned filmmaker Satyajit Ray. As a writer Upendrakishore Ray Chowdhury is best known for his retelling of epics and folklore; as a printer he pioneered the art of engraving and colour printing in India at the time when both were also being first tried in the West.
