Tau Beta Pi
The Engineering Honor Society
Tau Beta Pi History
The Tau Beta Pi Association was founded at Lehigh University in 1885 by Edward Higginson Williams Jr., to mark in a fitting manner those who have conferred honor upon their Alma Mater by distinguished scholarship and exemplary character as students in engineering, or by their attainments as alumni in the field of engineering, and to foster a spirit of liberal culture in engineering colleges.
Our Badge
The official badge of the Association is a watch key in the form of the bent of a trestle, engraved on the reverse side with the member's last name, chapter, and class. The colors of the Association are seal brown and white. The official quarterly magazine is The Bent of Tau Beta Pi. The name of the Association, its badge, and the title of its magazine are registered in the United States Patent Office. The creed of Tau Beta Pi, adopted in 1991, is Integrity and Excellence in Engineering.
The word key describes the insignia of many organizations. It comes from the fact that it was first designed, in the late eighteenth century, to include a pocket watch winding feature, hence key. The bottom stem, added to the basic insignia, had a tapered square hole fitting the common sizes of watch-winding shafts. The top stem and ring were added so the key could be worn as a pendant from a chain, rather than as a pin or badge, thus easily used to wind watches. When the 'stem-winder' watch was introduced in the late nineteenth century, it replaced the key-winder, however the insignia key remained, although with a vestigial hole now round for manufacturing ease and economy.
