Dmitry Ivanovich Mendeleyev (1834-1907) traveled to the United States in 1876 to visit the booming oil industry in western Pennsylvania. During his visit, he studied rock formations in the area, visited oil refineries, and interviewed people involved in the local oil industry. He then brought this knowledge back to Russia, which aided in building Russia's nascent oil industry. This publication documents his visit and contains a map of western Pennsylvania marking oil production centers throughout the region.</div>
