To etymologists, Burton Holmes is the charismatic traveler who coined the word travelogue to describe the lectures accompanied by slides and films that he gave in sold-out concert halls throughout the United States in the early 1900’s. To modern readers, Holmes is the master lensman behind exquisite, hand-colored photos in Travelogues (Taschen; $50), a chronicle of his decades of journeys across 39 countries—from Seoul, Korea, at the dawn of the 20th century, to May Day in Moscow, 1934.
