The scientific legacy of Birbal Sahni began with systematic investigations into the fossil plants of the Indian subcontinent, reshaping modern understandings of plant evolution. Born in Bhera in 1891, he bridged the gap between academic paleobotany and institutional development, establishing a dedicated research infrastructure that enabled India to contribute significantly to the global study of geological history.
Academic Foundation and Training
Sahni pursued his early education at the Mission and Central Model School and Government College University in Lahore. His interest in botany was cultivated by Shiv Ram Kashyap, alongside whom he traveled through regions including Chamba and Leh. He later moved to England, graduating from Emmanuel College, Cambridge in 1914. His advanced training included a doctorate from the University of London in 1919 and a brief research period in Munich with morphologist Karl Ritter von Goebel.

Upon returning to India, Sahni held positions at Banaras Hindu University and Punjab University before joining the University of Lucknow in 1921. As the first head of the Botany Department, he transformed the university into a primary center for botanical and paleobotanical investigation. This effort culminated in the 1946 founding of the Institute of Palaeobotany, which moved to its current site on University Road in 1949, shortly after the laying of its foundation stone by Jawaharlal Nehru.
Research and Paleobotanical Contributions
Sahni specialized in the fossilized flora of India, notably identifying the Bennettitalean plant Williamsonia sewardi and the petrified wood Homoxylon. His work extended to the study of living species like Ginkgo biloba and the classification of conifers, where he proposed the separate order Taxales. By analyzing wood remains from Harappa, he inferred historical trade links, and by examining the Deccan Intertrappean beds, he hypothesized that the Narmada region was once coastal.
Interdisciplinary Interests
Beyond his primary research, Sahni engaged in archaeology, numismatics, and geology. In 1936, he analyzed 100 BC coins and moulds excavated at Khokra Kot, documenting their manufacturing methods. His personal life included proficiency in playing the sitar and violin, alongside interests in chess and photography. His multidisciplinary approach and ability to integrate diverse observations influenced his students, including Mulk Raj Sahni and Ashok Sahni.
