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
Bras rapidly became a major industry over the 1930s, with improvements in fiber technology, fabrics, colours, patterns, and options, and did much better than the retail industry in general. Innovations included Warners' use of elastic, the adjustable strap, the sized cup, and padded bras for smaller-breasted women. In the US production moved outside of New York and Chicago, and advertising started to exploit Hollywood glamour and become more specialised. Department stores developed fitting areas, and customers, stores and manufacturers all benefited. Manufacturers even arranged fitting training courses for saleswomen. International sales started to form an increasing part of the U.S. bra manufacturer's market. Prices started to make bras available to a wider market, and home-made competition dwindled. Other major manufacturers of the 1930s included Triumph, Maidenform, Gossard, (Courtaulds), Spirella, Spencer, Twilfit, and Symington.
