Born Michael Rogers Oldfield Thomas on 21 February 1858, he became one of Britain's best-known mammalogists. He joined what is now the Natural History Museum in London in 1876, moved to the zoological department in 1878, and built a remarkable reputation for his work on mammals.
Thomas is especially remembered for the sheer scale of his scientific output. Working closely with collections from around the world, he described around 2,000 new mammal species and subspecies, making him a major figure in zoology and taxonomy. He was elected a Fellow of the Royal Society, a sign of how highly his work was valued in his own time.
He died on 16 June 1929. Though not a household name today, his influence remains woven into the history of natural science, especially in the study and classification of mammals.
