A Memoir of Pre-Partition Punjab is a richly annotated autobiography of Ruchi Ram Sahni (1863–1948)—social reformer, scientist, science educator, and, later, active participant in political affairs. A riveting account of life in nineteenth-century colonial Punjab, it covers Sahni’s growing up in a Hindu business family in Dera Ismail Khan in Waziristan, and captures the social, political and intellectual ferment of the times.
