Renzo Piano and Richard Rogers's Centre Georges Pompidou of 1971-1977 - the true prototype of the modern museum as popular architectural spectacle - wound up costing so much more than planned that the French government solved the shortfall by cutting support for several regional museums.

What a museum chooses to exhibit is sometimes less important than how such decisions are made and what values inform them. To have the crucial role of museum professionals usurped by self-serving tycoons in the name of economic imperative threatens not only the integrity of individual institutions but the very principle of art held in public trust.

Before the professionalization of architecture in the nineteenth century, it was standard for an aspiring mason or carpenter to begin his apprenticeship at fourteen and to become a master builder by his early twenties.

When Oscar Niemeyer died on December 5, 2012, ten days before his 105th birthday, he was universally regarded as the very last of the twentieth century's major architectural masters, an astonishing survivor whose most famous accomplishment, Brasilia, was the climactic episode of utopian High Modern urbanism.

Winning the Pritzker assures a flood of work in one's seventies and eighties, jobs necessarily carried out by assistants as the demands of modern-day cultural stardom and the inevitable waning of physical capacities prevent many architects from attaining the transcendent final phase more easily achieved by artists in other mediums.

Few developments central to the history of art have been so misrepresented or misunderstood as the brief, brave, glorious, doomed life of the Bauhaus - the epochally influential German art, architecture, crafts, and design school that was founded in Goethe's sleepy hometown of Weimar in 1919.

There can be little question that the tall building presents one of the most difficult challenges to the architect.
