Ivan Kulibin was born in the family of a petty merchant in the village of podnov'ye, Nizhny Novgorod district. At a young age he learned metalwork, lathe and watchmaking. In 1764-1767 years Kulibin built unique pocket watches. In their body in addition to its own clock mechanism was placed more and chiming mechanism, a musical device, reproducing multiple tunes, and the complex mechanism of the tiny theatre-automaton with moving figures[3].
Kulibin in 1792 and in 1799, was twice collected the famous clock "Peacock"[4] the work of the English mechanic James Cox, who are permanently on display in the pavilion hall of the Small Hermitage.
From 1769, and for over 30 years Kulibin he headed the mechanical workshop of the St. Petersburg Academy of Sciences. Supervised the production of machine tools, astronomical, physical and navigational instruments and tools.
1772 Kulibin developed several projects 298-meter arch bridge across the Neva river with wooden lattice trusses. He built and tested a large model of the bridge for the first time in bridge engineering practice showing the ability to model bridge structures. In subsequent years Kulibin invented and produced many original mechanisms, machinery and equipment. Among them — a spotlight with a parabolic reflector of tiny mirrors, a river ship with vozdeistvuya engine moving against the current (Vodohod), the mechanical crew with a pedal, improved grinding glasses for optical instruments.
(Иван Кулибин родился в семье мелкого торговца в селении Подновье Нижегородского уезда. В юношеском возрасте обучился слесарному, токарному и часовому делу. В 1764—1767 годах Кулибин изготовил уникальные карманные часы. В их корпусе помимо собственного часового механизма помещались ещё и механизм часового боя, музыкальный аппарат, воспроизводивший несколько мелодий, и сложный механизм крошечного театра-автомата с подвижными фигурками[3].
Кулибин в 1792 и в 1799 году дважды собирал знаменитые часы «Павлин»[4] работы английского механика Джеймса Кокса, которые постоянно экспонируются в Павильонном зале Малого Эрмитажа.
С 1769 года и на протяжении более 30 лет Кулибин заведовал механической мастерской Петербургской академии наук. Руководил производством станков, астрономических, физических и навигационных приборов и инструментов.
К 1772 году Кулибин разработал несколько проектов 298-метрового одноарочного моста через Неву с деревянными решётчатыми фермами. Он построил и испытал большую модель такого моста, впервые в практике мостостроения показав возможность моделирования мостовых конструкций. В последующие годы Кулибин изобрел и изготовил много оригинальных механизмов, машин и аппаратов. Среди них — фонарь-прожектор с параболическим отражателем из мельчайших зеркал, речное судно с вододействующим двигателем, передвигающееся против течения (водоход), механический экипаж с педальным приводом, усовершенствовал шлифовку стёкол для оптических приборов.
