Diwan Bahadur Kadambi Rangachari was an influential Indian botanist and ethnologist, recognized for his extensive contributions to the study of South Indian flora and ethnography. Born into a modest Tamil family, he faced early hardships after the death of his father, which compelled him to support his family through private tutoring. Despite these challenges, Rangachari excelled academically, graduating from Pachiappa's College and later earning his MA from Presidency College. His career began in teaching, but he soon transitioned to the Government Museum as Herbarium Keeper, where he began to make significant contributions to botany and ethnology. Rangachari is perhaps best known for his collaboration with Edgar Thurston on the seven-volume work, "Castes and Tribes of Southern India," which remains a critical reference for understanding the region's diverse cultures. His role as a senior assistant professor at Presidency College and later at the agricultural college in Coimbatore allowed him to influence generations of students. In recognition of his scholarly contributions, he was honored with the title of Rai Bahadur and later Dewan Bahadur. A founding member and president of the Indian Botanical Society, Rangachari's legacy endures through his work in botany and ethnography, which laid the groundwork for future research in these fields in India.
