Francis Fowke (7 July1823 - 4 December1865) was a British engineer and architect, and a captain in the Royal Engineers. Most of his architectural work was executed in the Renaissance style, although he made use of relatively new technologies to create iron framed buildings, with large open galleries and spaces.
Fowke was born in Ballysillan, Belfast. He studied at Dungannon, County Tyrone, and the Royal Military College, Woolwich. He obtained a commission in the Royal Engineers, and served with distinction in Bermuda and Paris. On his return to England, he was appointed architect and engineer in charge of the construction of several government buildings.
Before his sudden death from a burst blood vessel, he won the competition for the design of the Natural History Museum, although he did not live to see it executed. His renaissance designs for the museum were altered and realised in the 1870s by Alfred Waterhouse, on the site of Fowke's Exhibition building.
