Mikhail Timofeyevich Kalashnikov (UK: , US: ; Russian: Михаил Тимофеевич Калашников, IPA: [kɐˈlaʂnʲɪkəf]; 10 November 1919 – 23 December 2013) was a Soviet and Russian lieutenant general, inventor, military engineer, writer, and small arms designer. He is most famous for developing the AK-47 assault rifle and its improvements, the AKM and AK-74, as well as the RPK light machine gun and PK machine gun.

Kalashnikov was, according to himself, a self-taught tinkerer who combined innate mechanical skills with the study of weaponry to design arms that achieved battlefield ubiquity. Even though Kalashnikov felt sorrow at the weapons' uncontrolled distribution, he took pride in his inventions and in their reputation for reliability, emphasizing that his rifle is "a weapon of defense" and "not a weapon for offense".
