Leon Krier, the pioneering urbanist who designed Poundbury, the new town commissioned by Prince Charles in Dorset, England, will give the fourth annual David Lewis Lecture tonight at Carnegie Mellon University's Kresge Recital Hall in the College of Fine Arts building.

Krier's talk, called "An Urbanism for the Long Emergency," is free to the public and begins at 6:30 p.m. A public reception in the building's Great Hall will be held from 5 to 6:30 p.m.

"Leon Krier's distinguished international reputation derives deservedly from work that is at once metropolitan in scope yet intensely humanistic in its sensibilities," said Laura Lee, head of the School of Architecture. His values, she said, "parallel with values that David Lewis has embodied throughout his career."

Born in Luxembourg in 1946, Krier began in the 1970s to promote the classical and vernacular traditions in architecture and planning. As architect, author, critic, teacher and cartoonist, Krier began to make converts, including Andres Duany and Elizabeth Plater-Zyberk, two of America's leading New Urbanists.

"Krier introduced me to the idea of looking at people first, and to the power of physical design to change the social life of a community," Duany has said.

Krier has taught architecture and urban design at the Royal College of Arts (London), Princeton University, the University of Virginia and Yale University.

Lewis, who has taught urban design and architecture at CMU since 1963, is the founder of Urban Design Associates, which underwrites the lecture series in his honor.

Remaking Cornerstones

The CMU architecture school's Cornerstones symposium, now in its fifth year, is moving off-campus to the SouthSide Works Cinema for "Remaking the Pittsburgh Region," a collaboration with Oxford University, Yorkshire Forward, the National University of Singapore, the Monterrey Institute of Technology and Pittsburgh Regional Alliance.

"This year's symposium is a totally different and inspiring program from years past," said Cornerstones president Arthur Schwotzer, who called the SouthSide Works "the remaking of Pittsburgh at its best."

The symposium will examine what other cities have accomplished and how local communities, county and state government as well as business and community leaders can work together to build a revitalizing environment in the Pittsburgh region.

Gordon L. Clark, Oxford University professor of geography and head of the school's Centre for the Environment, will deliver this year's keynote address. Clark will discuss how globalized economic activity relates to local economic development, employment opportunities and income.

Kevin McMahon, president of the Pittsburgh Cultural Trust, will talk about remaking the Cultural District.

Architect and author Alan Simpson, Urban Renaissance Champion of the economic development agency Yorkshire Forward in England, will discuss new civic leadership.

The symposium will be held from 7 a.m. to 1 p.m. Oct. 5 and is open to the public. For information and registration fee, call Bob Johnston at 412- 268-9554.
