Ivan Vasilyev

He accompanied Leonty Andrianovich Hagemeister (1780–1833) on ship Neva to explore the coasts of Alaska and the North Pacific in 1806.

Vasiliev explored the Alexander Archipelago and the many coastal Islands in the area.

Krusenstern says this about Ivan Filippovich Vasiliev: It is much to be regretted that the hydrographic works of a naval officer, Vasilief, who was in the employment of the American Company, were lost...

Provided with a sextant and chronometer and with much zeal and attachment for his profession, he had during his sojourn in our American colonies made a complete survey of all of the Aleutian Islands without having had specific instructions to do so.

Unfortunately he was drowned in Okhotsk harbor on his return from America to Russia, and what became of his precious papers and drawings is unknown...[2] Ivan F. Vasiliev's name is spelt "Vasilief" in the United States, where he is also known as "Ivan Vasiliev the First", in order to differentiate him from other Russian mariners and early explorers of Alaska also named "Vasiliev".
