Chi Epsilon is the national civil engineering honor society. It was founded at the University of Illinois in the spring of 1922. The next year, Chi Epsilon was granted a certificate of incorporation as a national honor fraternity, and subsequently chapters were installed at the Armour Institute of Technology (now Illinois Institute of Technology) and the University of Minnesota. There are now more than 120 chapters which have initiated over 76,000 members.
Chi Epsilon is dedicated to the purpose of maintaining and promoting the status of civil engineering as an ideal profession. To this end, initiation into Chi Epsilon distinguishes the student of civil engineering who exemplifies the qualities of scholarship, character, practicality and sociability. At the same time, Chi Epsilon members have the responsibility of extraordinary service in the achievement of their profession.
In 1991, a local Civil Engineering Honor Society, Psi Delta Epsilon was formed at Lawrence Technological University. The members of this group petitioned the Supreme Council of Chi Epsilon for installation of a chapter in 1993. In 1994, LTU received approval from the Supreme Council and the 116 existing chapters. On December 3, 1994, Chi Epsilon chapter 117 was installed at LTU.
