NOLAN, Mary, American. The inventor of entirely new types of bricks. These construction blocks, which she called Nolanum, were hollow and fireproof, non-absorbent, insulating, and pest-proof. These building components were exhibited at the 1876 exhibition, as a model house using all interlocking bricks. An additional important feature was that these interlocking bricks were designed to not even need covering with paint or wallpaper. A complete mix of ultra-modern features all introduced at one time and in a single product.
