National History 
Delta Delta Delta was established after Sarah Ida Shaw and Eleanor Dorcas Pond met at Boston University.
There were several "ladies' societies" already established at the
University; however, Shaw
wanted to have a group that was different from the others. Shaw said to
Pond one day, “Let us found a society that shall be kind alike to all
and think more of a girl’s inner self and character than of her
personal appearance.” The two women then set out to create a new
national fraternity, and together they established the name, designed
the emblems, created the mottos and password, and wrote the
constitution and rituals.
Delta Delta
Delta was founded on November 27, 1888 at Boston University. The Alpha
Chapter (the first chapter) was then established with fourteen new
members joining in the fall including Florence Isabelle Stewart and Isabel Morgan Breed. By the end of the year, Tri-delta had 21
members; it had expanded and grown under the leadership of the two
founders and early Alpha Chapter members. For their leadership roles,
Sarah Ida Shaw, Eleanor Dorcas Pond, Isabel Morgan Breed, and Florence Isabelle Stewart are considered the four Founders of Delta Delta Delta.
With 136 chapters in the United States and Canada, Tri Delta is one of the largest women's organizations in the world.
