Birbal Sahni -Indian paleo botanist who studied the fossils of the Indian subcontinent. He also took an interest in geology and archaeology. He founded the Birbal Sahni Institute of Palaeobotany at Lucknow in 1946. His major contributions were in the study of the fossil plants of India and in plant evolution. He was also involved in the establishment of Indian science education and served as the President of the National Academy of Sciences, India and as an Honorary President of the International Botanical Congress, Stockholm. During his stint in England Sahni joined Professor Seward to work on a Revision of Indian Gondwana plants (1920, Palaeontologica Indica). In 1919 he briefly worked in Munich with the German plant morphologist Karl Ritter von Goebel. In 1920 he married Savitri Suri, daughter of Sunder Das Suri an Inspector of Schools in Punjab.

Janaki Ammal Edavalath Kakkat -Was an Indian botanist who conducted scientific research in cytogenetics and phytogeography. Her most notable works involve those on sugarcane and the eggplant. She has collected various valuable plants of medicinal and economic value from the rain forests of Kerala. Ammal taught at Women's Christian College, Madras, with a sojourn as a Barbour Scholar at the University of Michigan in the US where she obtained her master's degree in 1925. Returning to India, she continued to teach at the Women's Christian College. She went to Michigan again as the first Oriental Barbour Fellow and obtained her D.Sc. in 1931. Janaki is mentioned among Indian Americans of the Century in an India Currents magazine article published on January 1, 2000, by S.Gopikrishna & Vandana Kumar: "In an age when most women didn't make it past high school, would it be possible for an Indian woman to obtain a Ph.D. at one of America's finest public universities and also make seminal contributions to her field? The Kerala born Ammal was arguably the first woman to obtain a Ph.D. in botany in the U.S. (1931), and remains one of the few Asian women to be conferred a D.Sc. (honoris causa) by her alma mater, the University of Michigan. During her time at Ann Arbor she lived in the Martha Cook Building, an all-female residence hall and worked with Harley Harris Bartlett, Professor at the Department of Botany. She evolved a cross known as "Janaki Brengal", brengal being the Indian name for eggplant.
