Celebración del Centenario


Sigma Delta Pi, the National Collegiate Hispanic Honor Society, was founded on November 14, 1919, at the University of California, Berkeley by a junior undergraduate student named Ruth Helen Barnes.  Later that same academic year, on May 1, 1920, the first formal induction ceremony was conducted. Therefore, the Society’s centennial celebration begins January 1, 2019 and continues through July 31, 2020 with numerous initiatives and opportunities that will highlight Sigma Delta Pi’s 100-year history.

Each new member initiated during the 2019 calendar year received a special commemorative membership pin of the design posted above. Existing members of Sigma Delta Pi may also purchase this same pin for the cost of $10 through their home chapters.

During the spring 2020 semester, and to commemorate Sigma Delta Pi’s first formal induction ceremony on May 1, 1920 in Berkeley, CA, all new members will receive the Ruth Barnes’ commemorative pin that replicates the original presented to founding members.  Existing members may also purchase this same replica for the cost of $10 through their home chapters.

Book Cover 2020-final

In April 2020 and to commemorate the Society’s first 100 years, the College of Charleston’s Mark P. Del Mastro published an updated history of the organization: Sigma Delta Pi: Rediscovering a Century, 1919-2019 with Juan de la Cuesta Hispanic Monographs. Although the book is available directly through Amazon, special signed copies may be purchased from Sigma Delta Pi’s national headquarters (click here to order). While preparing this tome, Del Mastro also published multiple notes that highlight select aspects of Sigma Delta Pi’s collaboration during its history:

Also to commemorate Sigma Delta Pi’s centennial, Del Mastro organized a “Sigma Delta Pi History Panel” that was accepted and scheduled for presentation at the AATSP’s 102nd Annual Conference in Puerto Rico in July 2020.  Because of the conference’s postponement due to COVID-19, in early June 2020 participants recorded their respective presentations (click here to view the virtual panel).
