Professor Shonku (short story collection)

Professor Shonku is a collection of nine science fiction short stories by Satyajit Ray featuring the fictional scientist-inventor Professor Shonku. The collection was first published in 1965 by Calcutta publisher NewScript Publications.

The original collection contained seven stories, while the eight and ninth stories were added in later editions. Eight of the nine stories were published in the children's magazine Sandesh, while the ninth, "Professor Shonku o Bhoot", was previously published in Ashcharya. The short stories are written in epistolary form, using dated diary entries as a framing device.
