At the first meeting President Moore explained that, at the St. Louis
Exposition, according to wide-expressed opinions, the buildings had been
too far apart. He favored maximum of space with minimum of distance. The
architects first considered the conditions they had to meet, climate and
physical surroundings. They were mainly influenced by wind, cold and
rain.
The result was that for the Protection of visitors, they agreed to
follow what was later to be generally known, as the block plan, the
buildings arranged in, four blocks, joined by covered corridors and
surrounded by a wall, with three central courts and two half-courts in
the south wall. It had been developed in many talks among the
architects. Valuable suggestions came from Willis Polk and from E. H.
Bennett, of Chicago, active in the earlier consultations. The plan
finally accepted was the joint work of the entire commission.
Twelve buildings were put under contract, each designed to illustrate an
epoch of architecture, ranging from the severity of the early classic to
the ornate French renaissance of to-day.
