With the advent of industrialism and modernism, behavioral patterns have drastically evolved. The repercussions affect both architects and others concerned with the built environment. Nowadays, the relationship of architecture to technology and social issues is in utter disarray. To come to terms with this, I began compiling a list of figures from the last 2000 years who are relevant for the history of architecture – an archipedia of those who left a mark on the profession. It is comprised, in addition to significant practitioners of architecture, of many other individuals who have had a deliberate or incidental impact on the profession. I initially decided on 200 thinkers who have impressed their charisma on the world and the discipline, but as I proceeded, I realized that 200 is far from enough. It is a useful summary, but my goal has shifted to 2000.
