Prince Dmitry Petrovich Maksutov was a Russian rear admiral who participated in the defense of Petropavlovsk and became the last governor of Alaska.

He was born on May 12, 1832, in Perm and was baptized on May 13 in the family of the manager of the Perm provincial office, collegiate assessor Prince P. I. Maksutov.

In 1840, at the age of 8, he entered the Naval Cadet Corps, which he graduated from in 1847, receiving the rank of midshipman. On June 1, 1849, he was promoted to ensign. In 1849 and 1851, he served on the ship "Varna" and the frigates "Kagul" and "Midia," cruising off the coast of Abkhazia.

On March 28, 1851, Maksutov was promoted to lieutenant and assigned to the 46th Amur crew, after which he traveled through Siberia to the Far East. He sailed in the Pacific, Sea of Okhotsk, Sea of Japan, and South China Sea.

In mid-June 1854, he arrived in Petropavlovsk to participate in its defense. Commanding Battery No. 2, he distinguished himself in battle against the Anglo-French squadron. For his merits, he was awarded the Order of Saint George, 4th class: "Commanding Battery No. 2 of 11 guns with 127 lower ranks, he set an example of fearlessness for 8 hours in the battle on August 20, 1854, repelling the attack on Petropavlovsk port by the Anglo-French squadron, consisting of 3 frigates with 156 guns and a steamer with bombarding weapons, inflicting significant damage on enemy ships with accurate shots."

Dmitry Petrovich Maksutov was one of the most famous representatives of the Maksutov family. His brothers Alexander and Pavel also participated in the Crimean War. Pavel fought in the Black Sea and in the Battle of Sinop on the battleship "Paris" as a flag officer under Rear Admiral Novosilsky. Alexander and Dmitry defended Petropavlovsk. Dmitry commanded Battery No. 2, while Alexander commanded Battery No. 3, and both distinguished themselves in battle against the Anglo-French squadron. After this battle, both brothers were nominated for the Order of Saint George IV class (Alexander received a fatal wound in battle, and the award was presented to his family).

Dmitry Petrovich's grandson, Dmitry Dmitrievich Maksutov, became a renowned Soviet scientist and optician, inventing an optical system widely used in telescope construction. His granddaughter, Tatyana Dmitrievna Maksutova, dedicated her life to science and teaching, working at Leningrad State University. She is buried in St. Petersburg.
