19 August 1808 – Death of Fredrik Henrik af Chapman, Swedish admiral and shipbuilder (b. 1721)
Fredrik Henrik af Chapman (9 September 1721 in Gothenburg – 19 August 1808) was a Swedish shipbuilder, scientist and officer in the Swedish navy. He was also manager of the Karlskrona shipyard 1782-1793. Chapman is credited as the first person to apply scientific methods to shipbuilding and is considered to be the first naval architect.
Chapman is wearing a Sami (Lappish) jacket and the knight cross of the Order of Sword.
Chapman was the author of Architectura Navalis Mercatoria (1768) and several other shipbuilding-related works. His Tractat om Skepps-Byggeriet("Treatise on Shipbuilding") published in 1775 is a pioneering work in modern naval architecture. He was the first shipbuilder in Northern Europe to introduce prefabrication in shipyards and managed to produce several series of ships in record time.

He was ennobled as "af Chapman" in 1772, after the successful coup of Swedish king Gustav III.
Architectura Navalis Mercatoria
In 1765 Chapman applied for permission from his work as a chief naval builder for the Archipelago Fleet at the naval base at Sveaborg to work on Architectura Navalis Mercatoria, a collection of contemporary ship types that he considered to be the best and most interesting. The work had been commissioned by Duke Charles, the brother of king Gustav and was published in 1768. The book contained 62 illustrations of ships and smaller vessels, both Swedish and foreign designs. Some of these were Chapman's own designs, but many were also types that he had seen during visits to foreign countries. Everything from large warships to small fishing vessels were represented.
The book was intended for an international audience and the text was available in Swedish, French and English. All measurements were given in Swedish, French and English feet. However, it took seven years to finish the accompanying explanatory texts. The charts and the following Tractat om Skepps-byggeriet ("Treatise on shipbuilding") in 1775 launched Chapman as one of the leading experts on ship building in the world.

A further advance in the general theory was made on the appearance in 1775 of a work on the construction of ships by the Swedish Constructor—Admiral Frederick Henry de Chapman. This was translated into French by Vial du Clairbois, 1779, and into English by Dr. Inman, 1820. It contains the first published record of the use of Simpson's rules for approximate quadrature, and the calculations of displacement, centre of buoyancy, and metacentre given in the book closely resemble those made at the present day
