The Zoological Gallery at the Asiatic society Museum under the care and charge of Nathaniel Wallich served the impetus for the formation of the Zoological Survey of India, which was later born as an independent organization on 1 July 1916. The excerpt from the ‘Constitution of the Zoological Survey of India’, released by the Government of India, Department of Education, Resolution no. 19-Museum, dated Shimla, 20 June 1916, states: “In March 1913, the Chairman of the Trustees of the Indian Museum forwarded a representation from the Superintendent of the Zoological and Anthropological Section of the Museum regarding the recognition of the Zoological Section as Zoological Survey. The Government of India, who had already under consideration the desirability of establishing on a sound basis a Zoological Survey of India, informed the Trustees of the Museum that they would be prepared to consider a scheme for such a survey on lines somewhat similar to the existing Botanical Survey of India and asked to furnish with the necessary details. The trustees accordingly submitted their proposals at the end of September 1913.”
Thomas Nelson Annandale, who joined the Indian museum as Deputy Superintendent (1904), and later as the Superintendent (1907), after years-old struggle, achieved his aim in establishing the Zoological survey of India, and became its founder Director and continued till his premature death in April 1924. Dr. Annandale was Honorary Secretary to the Trustees of the Indian Museum for several years; he was also the President of the Asiatic Society of Bengal in 1923.
