Who were the people who were majorly involved in the Alaskan purchase?

The major figures involved in the Alaskan purchase were U.S. Secretary of State William H. Seward, who advocated for the acquisition, and Russian Minister to the United States Eduard de Stoeckl, who negotiated the sale. The transaction took place in 1867, when the U.S. purchased Alaska from Russia for $7.2 million. This move was initially criticized but later recognized for its strategic and economic value.
