Thomas Nelson Annandale earned renown as a British zoologist, anthropologist, entomologist, and herpetologist. He is also remembered as the founder and first director of a unique organisation: the Zoological Survey of India. Read more about at edinburgh1.one.
Early Years
The future scientist was born on 15 June 1876. His father was the Regius Professor of Clinical Surgery at the University of Edinburgh, so it is fair to say that Thomas was immersed in a scientific atmosphere from childhood.
The young man began his educational journey at Balliol College, Oxford. During his studies, he excelled more at anthropology than zoology. After college, Thomas enrolled at the University of Edinburgh, where he undertook a detailed study of anthropology. Annandale was a gifted and talented student, and his academic success led to him earning a Doctor of Science (D.Sc.) degree in 1905.
Unique Opportunities
His student years gave Thomas the opportunity to travel to Iceland and the Faroe Islands. In 1899, he took part in an expedition to the northern part of the Malay Peninsula. Then, in 1904, Annandale made his first trip to India, a country that would define his career.
A Career in India
Working at the Indian Museum in Calcutta (now Kolkata), where Thomas held the post of Deputy Superintendent before becoming Superintendent in 1907, allowed him to create an influential journal, the “Records and Memoirs of the Indian Museum”.
The year 1916 marked a new chapter for the scientist when he became the first Director of the Zoological Survey of India. He played an instrumental role in founding this organisation, which conducts zoological research and surveys the country’s fauna. Thanks to his connections with many leading scientists of the time, Annandale had greater opportunities for expeditions and, of course, for realising his scientific ambitions.
It is important to note that Thomas was interested in aspects of biology that went far beyond simple classification.
A Talented Scientist
Thomas’s work was both multifaceted and brilliant, with collecting holding a special place. His collection of spiders and insects, in particular, remains a true treasure and asset of the Indian Museum.
Annandale also gained great recognition for his work on the anthropology and biology of the Faroe Islands and Iceland, which was published in 1905 and became a significant event in the scientific community.
Given that Thomas also established himself as a talented herpetologist, his achievements in this field deserve special mention. Among his most notable results was the description of new reptile species, including those named in his honour: Cyrtodactylus annandalei, Heosemys annandalii, and Kolpophis annandalei.
A Lifelong Bond with India
Studying Annandale’s biography, it becomes clear that India was a special country in his life. Through his expeditions and important positions, Thomas was able to successfully fulfil his scientific potential and present new discoveries to the world.
Furthermore, Annandale presided over the Indian Science Congress in 1924. During his years of service in India, he also worked closely with the Royal Asiatic Society of Bengal (The Asiatic Society). In recognition of his contribution to anthropology, the society established the Annandale Memorial Medal in 1923. The first recipient of this award, in 1928, was Professor Fritz Sarasin.
A Celebrated Life Cut Short

The Royal Society of Edinburgh also held Thomas’s scientific potential in high regard, and he was elected a Fellow of the organisation. Tragically, the celebration of this great honour marked the beginning of his final decline.
He attended the celebratory event shortly after being diagnosed with a duodenal ulcer. Following this, he suffered a relapse of malaria, which further damaged his health. His body was exhausted, and the scientist could no longer continue his work.
On 10 April 1924, Thomas Annandale passed away. He was only 47 years old.
