Frank Lloyd Wright's First Boss Built This Highland Park Gem

At the 1893 Columbian Exposition in Chicago, Silsbee developed the award-winning "Moving Sidewalk" — the predecessor of modern moving walkways and escalators — and the West Virginia and North Dakota buildings, according to a biography from the Frank Lloyd Wright Trust. He also designed the Lincoln Park Conservatory, which was completed in 1895, according to the Cultural Landscape Foundation.
