Sigma Theta Tau International (STTI) Honor Society of Nursing

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 storge, tharros, and time, meaning love, courage, and honor.
