Design ideology reaches even the youngest members of our society, from the impetus behind new educational toys, for example, to the development of innovative new playground equipment. Swedish designer Ellen Key decided to examine this design history first in 1900 with her book, The Century of the Child, which charted the parallels between children's design and societal issues that had come to light. To honour this past landmark in design studies, New York's Museum of Modern Art organized an exhibition, "The Century of the Child: 1900-2000," which carried forward Key's work to look at how children's design has evolved (or stayed consistent) over the subsequent 100 years. The companion catalogue offers a fantastic survey of this significant exhibition.
