Julius Lindauer, United States patent 708773 (1902)
“ The objection to ordinary high corsets is that they are fitted with long steel busks, which extend up over a good part of the sternum, (or front part of the thorax,) thereby causing the corset to encircle the thoracic cage and exercise an injurious pressure on the organs contained therein, because they do not permit the chest to expand in the manner in which it expands when no corset is worn. In order to remove this inconvenience, extreme low corsets which cover the trunk from below the bust down only are often worn ”
