Sigma Delta Pi: Centennial Celebration and Replica Membership Pins for Spring 2020 Initiates


In Spring 2020, Sigma Delta Pi celebrates the centennial
of its first formal induction of new members that took place on May 1, 1920 at 1629 Walnut Street in Berkeley, CA under the leadership of undergraduate student Ruth Helen Barnes, the Society’s founder and first president.

To commemorate its inaugural initiation ceremony,
Sigma Delta Pi will issue a replica of Ruth Barnes’ original membership pin
to every new member inducted during the spring of 2020:


Current members may also purchase this special replica membership pin through their home chapters.

Sigma Delta Pi’s centennial celebration continues through July 2020,
and we encourage our chapters to plan local activities that are appropriate for this special period in our history.
