Sigma Theta Tau: Nu Phi Chapter

In 1922, six nurses founded Sigma Theta Tau International Honor Society of Nursing, today known as Sigma, at the Indiana University Training School for Nurses, which is now the Indiana University School of Nursing, in Indianapolis, Indiana, USA. The founders chose the name from the Greek words storgé, thárros, and timé, meaning love, courage, and honor. Sigma became incorporated in 1985 and is a nonprofit organization with a 501(c)(3) tax status in the United States.
