Sigma Delta Pi (), the National Collegiate Hispanic Honor Society
(), was established on at the
University of California, Berkeley. The society recognizes seven founding members but acknowledges an undergraduate UC Berkeley student named Ruth Barnes as its organizer and first president. On Friday, November 14, 1919, Barnes invited six other students of Spanish to her residence at 2545 Dwight Way to start what would eventually become the largest collegiate foreign language honor society in the U.S. Those six students who joined Barnes at her home were Miriam Burt, Ferdinand V. Custer, Anna Krause, Margaret Priddle, Ruth Rhodes, and Vera Stump • To honor those who excel in the study of Spanish language and in the study of the literature and the culture of the Spanish-speaking world; • To foster an understanding, appreciation and respect for the peoples, cultures and societies of the Spanish-speaking world; • To honor those who have promoted and reinforced a better understanding of the contributions of the Spanish-speaking world; and • To serve its membership in support of the Society's goals and ideals. Unlike many collegiate honor societies, Sigma Delta Pi was conceived, planned, and funded entirely by students, and for the first ten years of its existence they directed its activities, driving it to become a national society with sixteen chapters at universities across the United States. By 2011, it had 385 active chapters and had initiated 170,389 members. As of 2025, the Society has chartered over 640 chapters and initiated over 180,000 lifetime members. == Symbols ==
