The club was organized in New York City with 12 members in March 1868, by Jane Cunningham Croly. Among its founding members were Josephine Pollard, a children's author, and Fanny Fern, a popular columnist who had been angered at newspaper women being excluded from the all-male New York Press Club when it had an honorary dinner for the author Charles Dickens the month before. Sorosis was incorporated in January 1869. Alice Cary was the first president. Within one year, Sorosis had 83 members.
Sorosis is a latinate word meaning 'aggregation' (from the Greek sōros, meaning ‘heap’). Its object was to further the educational and social activities of women by bringing representative women of accomplishment in art, literature, science, and kindred pursuits.
The University of Texas at San Antonio houses a collection of records for the San Antonio chapter of Sorosis. The collection spans the years 1923 through 1991 and provides information about the club's members and activities primarily through minutes, photographs, scrapbooks and yearbooks.
