Dmitri Yakovlevich Laptev
Dmitri Jakowlewitsch Laptew ( Russian : Дмитрий Яковлевич Лаптев; * 1701 in Bolotowo near Velikije Luki ; † January 20 July / January 31, 1771 greg. Ibid) was a Russian polar explorer and naval officer.
Laptew, who entered the Navy in 1718 , first sailed the Gulf of Finland before he took part in an expedition to Arctic waters for the first time in 1730 .
In the course of the Great Nordic Expedition led by Vitus Bering , Dmitri Laptev was given the task of mapping the coast of Siberia from the mouth of the Lena to the mouth of the Anadyr . After a first unsuccessful attempt in 1737, he considered the task unsolvable because of the permanent coastal ice. But he was commissioned by the Admiralty to make a second attempt in 1739. Advancing east from the Lena estuary , Laptev reached the Indigirka River in the summer before his ship was trapped in the ice. After wintering, Laptev had smaller boats built in order to be able to maneuver better in the ice and in this way reached Cape Bykowski (Быковский мыс) east of the Kolyma estuary in 1740. After wintering again in the ice, Laptev finally decided to travel overland to the mouth of the Anadyr on the southern edge of the Chukchi Peninsula , from where he finally found a land route from the Anadyr fortress to eastern Kamchatka .
In the course of this expedition on water and on land, he mapped the Siberian coastline from the Lena estuary to the Kolyma. He also explored the catchment area and the delta of the Anadyr.
In 1741–1742 he returned and mapped the Anadyr and the Penschina . After this second expedition, Laptev returned to the Baltic Fleet , where he retired in 1762.
After Laptev is Dmitry Laptev Strait named those straits, the Lyakhov Islands separated from the Siberian mainland and the East Siberian Sea with the likewise after him (and his cousin Chariton Laptev named) Laptev Sea connects.
