cover: This 1884 painting by Ivan Fyodorov depicts the 1764 meeting of Empress Catherine the Great, seated in the foreground, and renowned Russian polymath Mikhail Lomonosov, at left. Often regarded as the “Russian Ben Franklin,” Lomonosov was at once a scientist, inventor, linguist, and historian; his poetry was as celebrated as his physics. To learn more about Lomonosov and his crucial role in the emergence of Russian science, see the article by Vladimir Shiltsev on page 40.
