Gaston Romazzotti
Gaston Romazotti was a French naval engineer of the late 19th and early 20th century, and an early designer of submarines. Early life. Romazotti was born at Molsheim, in Bas-Rhin, in July 1855. After studying at the École Polytechnique and qualified as a marine engineer before starting work at the Toulon Naval Yard in southern France. Career. At Toulon Romazotti worked with Henri Dupuy de Lôme and Gustave Zédé, both pioneers in submarine design, on the "Gymnote", one of the world's first all-electric submarines and the first functional submarine to be equipped with torpedoes. In  1897 he was appointed director of the Cherbourg Naval Yard, where Zédé had been working on "Sirène", completing her after Zédé's death and seeing her renamed "Gustave Zédé" in the late engineer's honour. That same year he started work on "Morse", a submarine of his own design, intended to combine the best features of both previous vessels. This was followed in 1900 with two more vessels, "Français" and "Algérien", which are referred to as the "Morse" class. In 1903 he oversaw the construction of the "Naïade" class of submarines, a set of 24 vessels built over a two -year period at Cherbourg. Romazotti favoured a single-hulled form, as opposed to the double-hulled submersible pioneered in France by Maxime Laubeuf, which brought the two men into conflict. Romazotti also used a copper alloy of his own devising, called Roma-bronze, which was intended to give a submarine's hull more flexibility than an all-steel hull, and which would interfere less with the use of a magnetic compass. In 1912 Romazotti became director of the Brest Arsenal, then central director at the Ministry of Marine, and was inspector-general of marine engineering in 1914. Romazotti died in  Paris in September 1915, aged 60 years.
