Phi Lambda Upsilon National Honorary Chemical Society () was founded in 1899 at the Noyes Laboratory of the University of Illinois. Phi Lambda Upsilon was the first honor society dedicated to scholarship in a single discipline, chemistry. Objectives The aims and purposes of the Society are summarized in its constitution – the promotion of high scholarship and original investigation in all branches of pure and applied chemistry. The founders envisioned a society dedicated to these objectives which would serve the field of chemistry in much the same manner as Phi Beta Kappa does the humanities; Sigma Xi, scientific research; and Tau Beta Pi, engineering. Throughout its history, Phi Lambda Upsilon has been consistently devoted to its objectives as an Honor Society. History Phi Lambda Upsilon was founded as an honorary chemical society in March 1899, at the University of Illinois. This was the first honor society dedicated to a single scientific discipline. A survey of our history reveals three distinct periods. Founding, growth and entrenchment of Alpha chapter at the University of Illinois comprise the first period. The second period began in 1906 when Beta chapter was established at the University of Wisconsin. Five more chapters were chartered prior to 29 June 1911, the date of the convention at Indianapolis at which the national society was organized and the second period reached its culmination. From 1911 to date, the Society has effected a gradual rise in the standards for membership. This period has also been characterized by the development of programs of activity within the chapters consistent with the honorary character of the Society. Phi Lambda Upsilon has installed more than seventy-five chapters with approximately 60,000 members. Membership Members are elected by the chapters or At-Large on the basis of their academic achievement and promise. Membership includes exceptional students of pure and applied chemistry selected from the junior, senior, or graduate classes, and also from well qualified members of faculties, staffs, as well as from selected post-doctoral students engaged in chemical endeavors in affiliation with qualified institutions of higher learning. Honorary Membership Honorary membership is the highest honor the Society may bestow upon an individual. Honorary members are scientists of national or international reputation in a field of chemistry and are chosen by a vote of the chapters. Regular membership in the Society in no way precludes later election to honorary membership. This honor has been bestowed upon only two
