American

Pioneers who were citizens of the United States, the largest single nationality among this atlas's energy pioneers, spanning the oil, electricity, nuclear and materials history of the American energy industry from Edwin Drake's first commercial oil well through Thomas Edison and George Westinghouse's power struggles to John B. Goodenough's battery chemistry. Belongs here: a pioneer whose primary national identity was American. Does not belong here: a pioneer of dual or hyphenated identity such as British-American or Italian-American, each grouped under its own hyphenated nationality rather than folded into American.
