Sigma History
Sigma Theta Tau was founded in 1922 by six nurses at Indiana University. The founders chose the name from the initials of three Greek words: 'storage,' meaning love, 'tharos,' meaning courage, and 'tima,' meaning honor--sigma, theta, tau. In 1985 the society was incorporated as Sigma Theta Tau International Honor Society of Nursing, a not-for-profit organization with 501(c)(3) status. The mission of Sigma and its chapters is to provide leadership and scholarship in nursing practice, education, and research to enhance the health of all people and to support the learning and professional development of its members who strive to improve nursing care worldwide. Sigma's vision is to create a global community of nurses who lead using scholarship, knowledge, and technology to improve the health of the world's people.
