Insignia
The colors of Tau Beta Pi are seal brown and white, which are the school colors of Lehigh. The official badge, called the Bent, is a watch key in the shape of the bent of a trestle (see picture). The trestle is the load-bearing part of the bridge, representing Tau Beta Pi's principle of Integrity and Excellence In Engineering. Originally the keys could be used to wind watches. However, because watches have since been fabricated with their own winding mechanisms, modern keys do not. The symbols on the Bent are an ancient form of Greek letters. The quarterly magazine of Tau Beta Pi is also titled The Bent.
