Sigma Theta Tau


In 1922, six nurses founded the Honor Society of Nursing, Sigma Theta Tau International (STTI) 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, tharsos, and timé, meaning love, courage, and honor. STTI became incorporated in 1985 as Sigma Theta Tau International Inc., a nonprofit organization with a 501(c)(3) tax status in the United States.
