Thomas Blakiston (1832-1891) was a British naturalist and explorer known for his contributions to the exploration and scientific study of North America and Asia. He was born on December 27, 1832, in Lymington, England, and passed away on October 15, 1891.

Key Contributions and Achievements:

1. Exploration of North America: Blakiston joined the British North American Boundary Commission in 1858, which was tasked with surveying and mapping the border between British North America (Canada) and the United States. He participated in several surveying expeditions in the western regions of North America.
2. Blakiston’s Line: During his time in North America, Blakiston made important observations about the distribution of animal species, particularly birds. He noticed a distinct boundary between the faunas of North America and Asia, which became known as “Blakiston’s Line.”
3. Natural History Research: Blakiston had a keen interest in natural history and collected numerous specimens of plants, animals, and fossils during his travels. He contributed significantly to the understanding of the flora and fauna of the regions he explored.
4. Exploration of Japan and Asia: After his North American expeditions, Blakiston joined the British Museum in London, where he worked as an assistant in the zoological department. He also traveled to Japan and other parts of Asia, contributing to the study of the region’s natural history.
5. Scientific Publications: Blakiston published several scientific papers and reports on his explorations and observations of the natural world. His work added to the knowledge of the geographical distribution and biodiversity of various species.
6. Honorary Membership: Blakiston was elected as an honorary member of the American Ornithologists’ Union in recognition of his contributions to the study of birds.

Thomas Blakiston’s explorations and scientific observations significantly contributed to the understanding of the natural history and biodiversity of North America and Asia. His work in defining “Blakiston’s Line” helped to establish a biogeographical boundary that still holds importance in the study of animal distributions. He is remembered as a dedicated naturalist and explorer who made valuable contributions to the fields of geography, natural history, and ornithology.
