Gennadi NevelskoiGennadi Nevelskoi
navigator. In 1848
Nevelskoi led the expedition in the Russian far east in the area of Sakhalin
island and the outlet of Amur
river. Not knowing about the efforts of Japanese navigator Mamiya Rinzo who explored the same area 40 years earlier, the Russian took Nevelskoi's report as the first proof that Sakhalin
is indeed an island, and named Strait of Tartary
in his honour.
