If a picture speaks a thousand words, then these incredible images speak volumes. The photographs below catalogue some of the most influential moments of the past 100 years, captured by professional photographers, opportunist photojournalists and intrepid explorers alike.
None of the photographs that have made this list (the Loch Ness Monster aside) have lost any of their emotional impact over the years, despite being reproduced thousands, and in some cases, millions of times. In fact, many have become more powerful and iconic, now that our feelings surrounding the documented events have matured.
