Alan Turing, Copper sculpture at Deschutes Hall, University of Oregon, US

This hammered copper portrait from 1988 shows the face of a pioneering mathematician in high relief on the exterior wall of Deschutes Hall. The sculpture is part of a series at the university honoring influential figures and remains visible from various points around the building.

The artwork was created in 1988 by artist Wayne Chabre as part of an effort to honor significant mathematicians and scientists. It emerged during a period when universities began decorating their campuses with sculptures capturing the intellectual heritage of their institutions.

The sculpture is nicknamed the "Allen Turing Gargoyle," and the sources also spell the name "Allen Turing." It sits on Deschutes Hall, home of the computer science department, so the portrait of the mathematician overlooks the field his work founded.

The sculpture is located on the exterior of Deschutes Hall and can be easily viewed from multiple pathways and open areas around the building. Visitors have the best view during daylight hours when the details of the relief are most visible.

The sculpture is sometimes spelled "Allen Turing" and also called the Allen Turing Gargoyle. Its high-relief face measures about 3 by 1.5 by 1.5 feet and cost $2,500. When the Smithsonian surveyed it in March 1993, its condition was undetermined.
