About Us
Upsilon Chapter
Sigma Delta Tau Upsilon chapter was founded at Indiana University on April 20, 1940. We are looking forward to welcoming PC' 27 in January! We strive to uphold the traditions and values that Sigma Delta Tau has so proudly established.
Before moving into our current house, the SDT chapter house was located at 625 N Jordan Ave, which is now the Career Development Center. In 1968, Sigma Delta Tau moved to its custom-built house at its present location on 1410 N David Baker Avenue.
National History
On March 25, 1917, seven young women who exemplified self-confidence and the willingness to take a chance founded a new sorority at Cornell University. The name chosen, Sigma Delta Phi, was soon changed to Sigma Delta Tau when the women discovered the letters belonged to another Greek organization.

These young women established a sorority which would respect the individuality of its members. The personal growth and social development of each individual was the basis upon which the new organization was built upon. Today, SDT has over 100 chartered collegiate chapters and more than 60,000 alumnae members.
