About TBP

The Engineering Honor Society

Tau Beta Pi (TBP) is recognized as the most prestigious engineering honor society in the United States, and the only engineering honor society open to all engineering disciplines. Our members demonstrate high achievement and integrity in engineering and work to positively influence the engineering community.

Notable Members

Tau Beta Pi’s exemplary members as well as its age contribute to its prestigious reputation. TBP is the second oldest honor society and the oldest engineering honor society established in the United States. Today, it boasts over 250 collegiate chapters with 617,000+ total initiated members. Some of our notable members include:

The national organization as well as our Purdue chapter offer resources, support, and a community of ambitious engineers to collegiate and alumni members. Tau Beta Pi is a proud, distinguished, and exclusive network of engineers.

Exemplary Character and Distinguished Scholarship

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.

Purdue Chapter History

The Purdue University chapter of Tau Beta Pi is known as the Indiana Alpha chapter. “Indiana Alpha” indicates that it is the first chapter founded in Indiana. Our history dates back to April 10, 1893 when our chapter was established. There are only two chapters — one at Lehigh University and one at Michigan State University — that predate ours, and we are proud of our history as the 3rd oldest chapter of TBP.

Over the years, we have initiated over 12,200 members, including Gus Grissom (IN Alpha 1950), who is the second American to fly in space, and Stephen D. Bechtel Jr. (IN Alpha 1946), who was the co-owner of Bechtel Corporation.

Purdue Members

Members of the Indiana Alpha chapter are ambitious students who not only pursue academic excellence, but also strive to confer honor upon their alma mater through community service and professional development. Whether TBP members are conducting research, contributing to innovative projects and student engineering organizations, working for the Purdue University School of Engineering, serving as Teaching Assistants, leading tutoring sessions, or performing community service, they are a vital component of Purdue Engineering.
