Thousands moved to Gary in the early 1900s for work in burgeoning steel industry. Providing housing quickly and affordably, Thomas Edison's 1906 proposal of pouring a concrete mixture into a single mold for the facades, roof, stairs, walls, and other parts of a house was adopted for company housing (Edison was not directly involved).
