         Among the great Russian inventors of the past an honourable place is held by I.P.Kulibin.
         When quite young, he specialized in making watches of different size and appearance, some of them being spoken
of as an 18th century wonder. Later Kulibin built the so–called planetary watch, the latter showing not only the day of the
month, the week, the month, the season, the hour, the minute and the second, but also the quarter second. Kulibin's art
having attracted attention in the capital, he was taken on as a mechanic at the St.Petersburg Academy of Sciences.
         While there, Kulibin created many useful things, the project of onespan bridge which was to be built across the
Neva being one of them.
         In 1779 Kulibin made a lantern which could cast a powerful beam of light a long distance ahead. The lantern was
made of a great number of small mirrors arranged so that they intensified the light of a single candle placed in its centre 500
times. But to his disappointment the lantern was mostly used for amusements.
         Having retired in 1801, Kulibin returned to Nizhny Novgorod and was soon forgotten, with many of his inventions
unused and some of his projects unfinished. He died a very poor man.
