Tau Beta Pi Founded in 1885 at Lehigh University
Dr. Edward H. Williams Jr., a professor at Lehigh, saw the need and created an honor society to recognize technical men for superior scholarship and exemplary character. On June 15, 1885, the first member of Tau Beta Pi was initiated. He was Irving A. Heikes, valedictorian of the Lehigh class of 1885, and he assisted in organizing the Pennsylvania Alpha Chapter, Tau Beta Pi's first student chapter.

1895
First Convention held in Cleveland, Ohio
At Michigan State College, the Michigan Alpha Chapter was born in 1892, and Purdue's Indiana Alpha followed in 1893. There were now enough chapters to hold a Convention, and on May 28, 1895, the first Convention was held in Cleveland.

1906
First issue of The Bent quarterly magazine
The Bent of Tau Beta Pi was first published by the Pennsylvania Alpha Chapter in April of 1906. A subscription cost one dollar per year. Today, the magazine is available in both paper and digital versions and total paid circulation exceeds 88,000 copies per issue. Annual subscriptions are $10 and a lifetime subscription is $95 for paper and $45 for electronic.

1907
Headquarters moved to the University of Tennessee
In 1907, Tau Beta Pi's first Secretary of the Association, R.C. Matthews, moved the national Headquarters to the campus of the University of Tennessee, Knoxville, where he was an instructor. In 1963, the staff moved into a suite of offices designed for Tau Beta Pi in the Nathan W. Dougherty Engineering Building and are located there today.

1928
Fellowship Program established
The 1928 Convention adopted the Fellowship Program to finance, for a select group of members chosen for merit and need, a year of graduate study at the college of their choice. Fellows with stipends receive $10,000 for their advanced study with a total of 1,736 Fellowships and more than $8 million in stipends given since the program began. Tau Beta Pi was the first honor society to establish such a program which aspires to advance engineering education and the profession.

1936
Women recognized by Women's Badge
In 1936, Tau Beta Pi began to formally recognize outstanding women in the field of engineering. Katharine Cleveland, of Kentucky Alpha, was the first to wear the Women's Badge.

1969
Women Given Full Membership Status
Though there were women scholastically eligible for membership in Tau Beta PI as early as 1903, it was not until 1969 that they were offered full membership. Katharine Cleveland Harelson, the first recipient of the Women's Badge, was initiated into full membership on April 18, 1969.

1974
Merger of Tau Beta Pi and Sigma Tau
Until 1974, there were two general engineering honor societies in the United States, Sigma Tau and Tau Beta Pi. Sigma Tau was founded in 1904 at the University of Nebraska, and in 1973, had 34 chapters and 40,000 members. The 1973 Convention of Tau Beta Pi approved the merger of the two organizations. Now engineering excellence was recognized by a single, strong organization and the merger suddenly increased the number of chapters to 172.

1985
Tau Beta Pi Celebrates One Hundred Years
As Tau Beta Pi celebrated its one hundredth birthday in 1985, it had grown to 192 collegiate chapters and more than 296,000 members. The Convention returned to Lehigh for the dedication of a Tau Beta Pi Centennial Conference Room in Packard Laboratory. Famed writer Isaac Asimov and Lee Iacocca, then chairman of the Chrysler Corporation, each spoke to crowds of 700 people at the Centennial Symposium and the Second Century Awards Banquet.

1988
Award-winning Engineering Futures Program Established
Engineering Futures has grown to serve as many as 4,000 engineering students each year. The curriculum, taught both virtually and on campus by Tau Beta Pi volunteers, prepares engineering students for their careers by teaching interpersonal skills, teamwork development, problem solving, and presentation skills.

1998
Tau Beta Pi Launches Scholarship Program
The Tau Beta Pi Scholarship Program was established with five of nine awards named in honor of former Secretary Treasurer Emeritus Bob Nagel. Given to members for their senior year of full-time study, the $2,000 scholarships are funded by gifts from alumni and corporations, the largest being a $4.3 million bequest from LeRoy Record of Kansas Alpha. Tau Beta Pi awards approximately 250 scholarships each year.

2011
International Honor Society
The first international initiation occured at Texas A&M University at Qatar.
