Mikhail Nikolaevich Beklemishev, born on September 14 (26), 1858, in the village of Bozheninovo, Alexin district of Tula province, was a Russian naval officer and engaged in submarine construction. His father, Nikolai Petrovich Beklemishev, served as a naval officer and participated in the defense of Sevastopol during the 1853-1856 war. After being severely wounded in 1855, he retired with the rank of lieutenant in 1858.

Mikhail Beklemishev graduated from the Technical School of the Naval Department in 1879, receiving the rank of ensign in the naval service. In 1884, after studying at the Mine Officer Class, he became a second-class mine officer, and in 1886, a first-class mine officer. In 1885, he received the rank of sub-lieutenant in the admiralty, and in 1891, he graduated from the Naval Academy with specialties in shipbuilding and mechanical engineering. After being reclassified from lieutenant to midshipman, he taught at the Mine Officer Class and served on ships of the Baltic Fleet. In 1901, Beklemishev joined the commission for designing submarines.

Together with I.G. Bubnov and I.S. Goryunov, he developed the project for the submarine "Dolphin," built at the Baltic Plant. This submarine had a range of 240 miles and a speed of 10 knots, surpassing foreign counterparts. Beklemishev oversaw the construction and testing of the submarine, receiving the rank of captain of the second rank and becoming its first commander. Later, he trained crews for new submarines. In 1904, the "Dolphin" and other submarines were sent to Vladivostok, which forced the Japanese to abandon the naval blockade of the city.

In 1905, Beklemishev, now a captain of the first rank, participated in the creation of a training unit for underwater navigation. In 1908-1909, he headed the underwater navigation department of the Naval Technical Committee, and in 1910, he became a member of the committee and head of the underwater navigation department of the Main Naval Staff. That same year, he retired with the rank of major general in the admiralty and was awarded five orders.

After retirement, Beklemishev taught at the St. Petersburg Polytechnic Institute and worked as a consultant at the Baltic Plant and the Dynamo Plant. In 1918, he participated in the shipbuilding commission, and in 1919, he headed the underwater department of the Main Shipbuilding Directorate. In 1920, he was arrested but soon released. Later, he worked at the Special Technical Bureau of the Supreme Council of National Economy, commanded the ship "Mikula," and was arrested again.

In 1931, Beklemishev retired. In 1935, he was arrested again but released. Mikhail Nikolaevich Beklemishev died on February 18, 1936, in Leningrad and was buried at the Nikolsky Cemetery, although his grave has not survived.
