[1] Eduard was born in 1804 in Constantinople, Ottoman Empire, where his father, Andreas von Stoeckl, was serving as an Austrian diplomat.

[3] Stoeckl established close friendly relations with many American officials and politicians, including the senator and the future Secretary of State William H. Seward, with whom he would later negotiate the Alaska purchase.

Stoeckl advocated the sale of Alaska (then known as Russian America) to the United States, asserting that this would prevent the United Kingdom from seizing the territory in case of war between the two countries and would allow Russia to concentrate its resources on Eastern Siberia, particularly the Amur River area.

He also insisted that by doing so, Russia would avoid any future conflict with the United States, viewing further U.S. expansion in North America as inevitable.

[6] Due to declining health, Stoeckl resigned in 1869 and was made a Knight of the Order of the White Eagle on 20 April 1869.
