Breast augmentation
The modern prosthetic breast was invented in 1961, by the American plastic surgeons Thomas Cronin and Frank Gerow, and manufactured by the Dow Corning Corporation; in due course, the first augmentation mammoplasty was performed in 1962. There are five generations of medical device technology for the breast-implant models filled with silicone gel; each generation of breast prosthesis is defined by common model-manufacturing techniques.
History of bras
It has been said that the bra took off the way it did in large part because of World War I, which shook up gender roles by putting many women to work in factories and uniforms for the first time. The war also influenced social attitudes toward women and helped to liberate them from corsets. But women were already moving into the retail and clerical sectors. Thus the bra emerged from something that was once discreetly tucked into the back pages of women's magazines in the 1890s, to prominent display in department stores such as Sears, Roebuck, and Montgomery Ward by 1918. Advertising was now promoting the shaping of the bust to contemporary fashion demands, and sales reflected this.
