This collection consists of materials related to the Trigère family, especially Robert (Sioma) Trigère, ranging in date from approximately 1910 to 2010. Sioma Trigère was a Russian-born French-American businessman who partnered with his sister Pauline, a designer, to create Trigère, Inc., which became a leading New York fashion company. The collection is primarily comprised of Sioma Trigère’s collected correspondence, mainly to family members, especially Pauline and her first husband, Lazar Radley, but also their son Jean-Pierre Radley, Pauline and Sioma’s mother Cecile, and Sioma’s daughter Jane, as well as a small amount of Pauline’s correspondence. The letters document the family's business, with a special emphasis on their time in France (1905-circa 1936), and in New York during the 1960s and 1970s. There are also materials related to longtime family business associate and friend Leon Hendline, documenting his parallel journey from Russia to France to the United States. The collection also contains a varied set of family photographs, from throughout the overall period, and a small number of documents connected to assorted aspects of the business. The collection is unprocessed. A preliminary inventory is available in the department.
