Biography
After serving the Russian army during the Seven Years' War as quartermaster general, he was appointed governor of Novgorod in 1764 by Catharine II. He introduced the cultivation of potatoes to Russia, regulated the postal services, and was instrumental in the abolition of torture in 1767.

Based on Sievers' initiative, the provincial government reform was instituted; he was himself appointed general governor of Novgorod, Tver and Pskov. He was Russian ambassador to Poland and led the second and third partition of the kingdom. Czar Paul appointed him senator in 1796; in 1797 he became head of the new department for water communications. He was knighted in 1798.

In Sievers' honor, Alexander I named the channel that connects the outlet of the Msta river with the Volkhov river the Sievers channel.
