Sergey Ivanovich Mosin was born on April 2, 1849 in Ramon, Voronezh oblast, Russian Federation.
Sergey Ivanovich entered into a military academy at age 12 where he excelled as a young officer. In 1867, he entered the Alexandrovskoye Military High School in Moscow. Upon leaving Alexandrovskoye in 1870, he decided to go to the artillery branch and transferred to the Mikhailovskoye Artillery Academy. He graduated in 1875 and transferred to the Tula Arsenal where he became the head of the machining division.
It was at Tula where Sergey Ivanovich began his career as a weapons designer by first making improvements to the Berdan II and later collaborating with Nagant to design the Rifle of Three Lines of the Year 1891. Some details in Mosin's rifle were borrowed from Léon Nagant's design. The initial rifle proposed by Mosin lacked an interrupter, leading to numerous failures to feed. This detail was introduced in the rifle borrowing from Nagant's rifle.
Sergey Ivanovich eventually rose to the rank of Major General and was appointed as the director of the Sestroretsk arsenal. He died on February 8, 1902 and was buried in Sestroretskoye Cemetery in St. Petersburg Sestroretsk.
