John George Children

John George Children. He was a pivotal English scientist whose career bridged the late Georgian era and the early Victorian era, making significant contributions as a chemist, mineralogist, and entomologist. Serving as a keeper at the British Museum, he played a crucial role in expanding and cataloging the national collections, while his independent electrochemical research earned him a lasting reputation in the scientific community. His work was recognized by his peers through his fellowship in the Royal Society, where he also served as secretary.

Early life and education

Born at Ferox Hall in Tunbridge Wells, he was the son of George Children, a banker and fellow of the Royal Society. He received his early education at Eton College before matriculating at Queens' College, Cambridge, though he left without taking a degree. His scientific interests were nurtured from a young age within an intellectual family environment, and he developed an early passion for natural history. Following his time at Cambridge, he managed the family estate at Tonbridge, where he conducted his first independent chemical experiments.

Career at the British Museum

In 1816, facing financial difficulties after the collapse of the family bank, he secured a position as an assistant librarian in the Department of Antiquities at the British Museum. His scientific acumen led to his appointment in 1817 as the first keeper of the newly established Department of Natural History and Modern Curiosities, a precursor to the modern natural history departments. He was instrumental in acquiring and organizing major collections, including the important insect collection of William Jones. Children later oversaw the transfer of the natural history collections to the new British Museum (Natural History) in South Kensington, now the Natural History Museum, London.

Scientific contributions

His most notable scientific work was in electrochemistry, where he constructed a massive voltaic pile with plates donated by King George IV, which was then the largest in England. Using this apparatus, he successfully isolated the element tantalum in metallic form for the first time and conducted extensive experiments published in the Philosophical Transactions of the Royal Society. In entomology, he described numerous species and his collection formed a core part of the British Museum holdings; the snake Children's python (Antaresia childreni) was named in his honor by John Edward Gray. He was a active member of several learned societies, including the Linnean Society of London and the Royal Institution.

Personal life and legacy

He married Hester Anna Holwell, granddaughter of William Holwell, and their son, John Children, became a noted etcher and painter. Following his first wife's death, he later remarried. His home in London and later at Halstead Place in Kent were frequent meeting places for leading scientists like Sir Humphry Davy and Michael Faraday. He died at Halstead Place and was buried at St. Lawrence's Church, Seal. His legacy endures through the species named for him and his foundational work in building the national natural history collections, which influenced future generations of scientists including his assistant, John Edward Gray.
