where did the glass ceiling term come from
Glass ceiling The first person to use the phrase was Marilyn Loden, during a 1978 speech.[15][16] The concept of the glass ceiling was later popularized at the National Press Club in July 1979.[citation needed] This was at a Conference of the Women's Institute for Freedom of the Press led by Katherine Lawrence of Hewlett-Packard. This was part of an ongoing discussion of a clash between written policy of promotion versus action opportunities for women at HP.
The Crystal Palace The Crystal Palace was a cast-iron and plate-glass structure originally built in Hyde Park, London, to house the Great Exhibition of 1851. More than 14,000 exhibitors from around the world gathered in its 990,000-square-foot (92,000 m2) exhibition space to display examples of technology developed in the Industrial Revolution. Designed by Joseph Paxton, the Great Exhibition building was 1,851 feet (564 m) long, with an interior height of 128 feet (39 m).[1] It was three times larger than the size of St Paul's Cathedral.[2] The introduction of the sheet glass method into Britain by Chance Brothers in 1832 made possible the production of large sheets of cheap but strong glass, and its use in the Crystal Palace created a structure with the greatest area of glass ever seen in a building and astonished visitors with its clear walls and ceilings that did not require interior lights.
