scope:

This vividly illustrated history of the International Congress of Mathematicians - a meeting of mathematicians from around the world held roughly every four years - acts as a visual history of the 25 congresses held between 1897 and 2006, as well as a story of changes in the culture of mathematics over the past century. Because the congress is an international meeting, looking at its history allows us a glimpse into the effect of wars and strained relations between nations on the scientific community.
