In recent years Louis Kahn’s messy personal history has threatened to overshadow his immense professional accomplishments, yet his aura has grown steadily, not just for what he achieved but also because of what has taken place in the built environment since his death. After he almost single-handedly restored architecture’s age-old status as an art form, his legacy was quickly squandered by younger coprofessionals. From the mid-1970s onward they have careened from one extreme, short-lived stylistic fad to the next—Postmodernism, Deconstructivism, Blobitecture—and lost sight of the profound values Kahn wanted to convey: timelessness, solidity, nobility, and repose.
