Ratan Lal Brahmachary (listen Bengali: [Ratana lāla brahmacārī])(1932 - 13 February 2018) was a distinguished scientist and a pioneer of tiger pheromone studies in India. He was widely known for his research in pheromones, although his academic background based on Physics, specifically on astrophysics under guidance of S.N. Bose. Brahmachary made significant contributions in tiger behavioral studies researching the animal for over 50 years. He studied many species of wildlife, notably big cats and undertook research trips to his favourite continent Africa fourteen times. Brahmachary studied ethology in the Amazon basin in South America and Borneo, Indonesia with an ardent admirer of entomologist Gopal Chandra Bhattacharya.

He once said in an interview

Biology is as fascinating as probing the mysteries of the physical universe. The inner universe of an organism or of an ecosystem is as challenging as the outer Universe of the expanding cosmos

He died in pneumonia on 13 February 2018 in a city Nursing home in Kolkata, India. Brahmachary had pledged his body to medical research. After paying respect his body was handed over to Radha Govinda Kar Hospital authorities.
