Philip Henry Gosse (6 April 1810 – 23 August 1888), known to his friends as Henry, was an English naturalist and popularizer of natural science, virtually the inventor of the seawater aquarium, and a painstaking innovator in the study of marine biology. The aquarium craze was launched in early Victorian England by Gosse who created and stocked the first public aquarium at the London Zoo in 1853, and coined the term "aquarium" when he published the first manual, The Aquarium: An Unveiling of the Wonders of the Deep Sea, in 1854.
