[1] Feodor Dmitriyevich Motorin (Фёдор Дмитриевич Моторин) (1630s–1688) began his career at the Moscow Cannon Yard in 1651 along with another famous bellmaker Alexander Grigoriev.
After having accumulated some financial capital, he began purchasing land and buildings for his colleagues-bellmakers in the Pushkarskaya Sloboda in the 1660s.
Dmitry Motorin is known for his unusual 64 kg bell, cast by him in 1687 at the request of a boyar Vasily Golitsyn for the Church of Pokrova Bogoroditsy in his votchina of the village Medvedkovo (it can be seen in Kolomenskoye today).
In 1692, he cast a 1-tonne bell for the Church of John the Apostle in Bronniki (moved to the Saint Basil's Cathedral).
In 1695, Ivan Motorin made a 3-tonne bell for the Church of Saint Nicholas in Moscow (destroyed in the 1930s).
In February 1701, after heavy artillery losses in the Battle of Narva, Peter the Great ordered to use Motorin's bellmaking factory for cannon production.
A famous cannon maker Martyan Osipov (Мартьян Осипов) assisted Ivan Motorin in mastering the science of cannon-making.
Motorin's factory carried out the order in a short period of time and produced 113 copper cannons by February 1702.
In 1714, Ivan Motorin cast the 2-ton Alarm Bell (Набатный колокол), which was later placed on top of the Tsarskaya Tower of the Moscow Kremlin.
