A native of Bayonne, Jauréguiberry entered the French Navy in 1831. He rose steadily through the ranks, becoming a lieutenant in 1845, a commander in 1856, and a captain in 1860. After serving in the Crimea and in China, and being governor of Senegal, he was promoted to rear admiral in 1869.
Jauréguiberry served in the Crimean War as commander of the gunboat Grenade, distinguishing himself at the capture of Kinburn on 17 October 1855. He was twice commended for his conduct in orders of the day.
He served on land during the second part of the Franco-Prussian War, in the rank of auxiliary general of division. He was present at Coulmiers, Villepion and Loigny-Poupry, in command of a division, and in Chanzy's retreat upon Le Mans and the battle at that place in command of a corps.
Jauréguiberry was the most distinguished of the many naval officers who did good service in the military operations. On the 9th of December he had been made vice admiral, and in 1871 he commanded the fleet at Toulon; in 1875 he was a member of the council of admiralty; and in October 1876 he was appointed to command the evolutionary squadron in the Mediterranean.
In February 1879 he became minister of the navy in the Waddington cabinet, and on the 27th of May following was elected a senator for life. He was again minister of the navy in the Freycinet cabinet in 1880. A fine example of the fighting French seaman of his time, Jaureguiberry died at Paris in October 1887.
Two French ships have been named in the admiral's honour, the pre-dreadnought battleship Jauréguiberry, in service from 1897 to 1919, and the Fleet escort (T 53 class destroyer) Jauréguiberry, in service from 1958 to 1977.
