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.

All architecture, classical or not, must have some sense of order, and order is much harder to achieve without the straight lines and right angles that have dominated the building art from time immemorial.

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.

Architecture was the last of the major professions to devise a formal 'cursus honorum' before its practice could be undertaken.

The truth be told, the World Trade Center was neither a very good work of architecture nor a very successful piece of urbanism. Its shortcomings were somewhat mitigated by the westward and southward expansion of the World Financial Center and Battery Park City during the 1980s.

The financial benefits of prefabrication have never been as large as its advocates predicted, for although some labor costs can be reduced by machine manufacturing, on-site assembly of any building still depends to some extent on the handwork of skilled craftsmen.

During the nineteenth century, the rapid emergence and proliferation of new manufacturing methods and building technologies led to the establishment of polytechnic schools that concentrated on the practicalities of engineering and construction rather than the niceties of stylistic correctness or adherence to established precedent.
