Warner Brothers Corset Manufacturer. Two brothers, Dr. I. DeVer and Lucien C. Warner, formed small business partnership for corset manufacturing in 1874. By 1876, they had built a corset production facility in Bridgeport which eventually covered two entire blocks in the city's South End. The Warner Brothers Company became the leading producer of boneless, flexible corsets in the United States and continued to develop a long line of products such as the first two-way stretch girdle and the first line of bras utilizing the A-B-C-D sizing system. It remained an innovator in the world of women's lingerie by introducing new designs, fabrics, and technology for women's undergarments, adapting to the dictates of changing times and fashions. The Warner Company also established the Seaside Institute, which served as an educational housing facility for the many young women who came to the city to work for Warner Brothers. As early as 1912, Warner’s was the largest corset manufacturer in the world and employed 3,300 workers.
