One hundred days have been identified by Getty and National Geographic to represent defining moments of the past 150 years.

These moments are crystallised in images that leap from the page revealing joy, anger, despairsand triumph. An insightful text by photography historian Nick Yapp supports these images, which are accompanied by journals, excerpts and 'on-site' notes that offer the backstory of the image and how it was captured. Major events that have shaped our erascaptured in the book include, from the Getty historic archive, the 1848-9 revolution and riots in Europe; President Lincoln's assassination in 1865; the construction of the Eiffel Tower in 1889; the Potemkin Mutiny (1905) that launched the Russians Revolution; the Easter Rising in Dublin in 1916; the Wall Street crash of 1929; Kristallnacht in Germany in 1938; the Bristish leaving India in 1947; through to the dawn of the new millennium in 2000.

The National Geographic archives are used to illustrates cultural geography, the changes in landscape, contemporary conflicts, Native America, and the civil rights movement among others, including the 1906 San Francisco earthquake, Scott and Amundsen reaching the South Pole in 1911; the Lascaux cave paintings discovered in 1940; the first heart transplant in 1967; the Chernobyl disaster of 1986; the cloning of sheep in 1997; the Twin Towers attack of 2001; and the global warming debate of 2007.

The wonder of this book is in illustrating how an entire event or age can be captured in a single image - whether it be of a peasant's tears, two heads of state sharing a secret, or the triumph of an Olympic champion. Politics, war, crime, exploration, fashion and fads all make up these one hundred days: From the California Gold Rush of 1849 to the finished structure of the Three Gorges Dam in 2006.
