Sébastien-François Bigot was born on 1 March 1706 in Brest, France.

An artillery specialist, he served in the Royal-Artillerie then the French Navy. In 1759, he commanded the 70 gun Le Magnifique, including at the Battle of Quiberon Bay. He was the first director of the Académie de Marine.^[1] In 1763, he published Tactique navale, which was of such quality that it quickly became known in English and Dutch translations. He was made a lieutenant-general in the Navy in 1771.

At least three roads in Brittany bear his name, according to the 1997 book Les Noms qui ont fait l'histoire de Bretagne.
