Architect and collector Norman Brosterman first became interested in the history of kindergarten while assembling the world’s finest collection of antique building block and construction toys, later acquired by the Canadian Centre for Architecture in Montreal.

Discovering that the famed Froebel Blocks—well-known to all students of Frank Lloyd Wright—were merely part of a much larger system of elegant, nature-based, pedagogical toys, Brosterman embarked on years of research into the history of this lost world, culminating in the publication in 1997 of his award-winning book, Inventing Kindergarten.
