Joseph Eichler built 11,000 homes between 1949 and 1966, and every one of them was modernist. Working with architects including Anshen + Allen, Jones & Emmons, and Claude Oakland, he proved that good design could be affordable, democratic, and profoundly human. The hallmarks—post-and-beam construction, floor-to-ceiling glass, open plans, and indoor-outdoor atriums—are now standard in high-end architecture, but in the 1950s they were revolutionary.
