While working in Haarlem at the military hospital in 1851, Mathijsen first used plaster of Paris as a bandage. [1] Until then a Belgian method was used with starch that took up to a day to dry and harden. [1] Across the street he watched workers repairing cracks in the church with strips of jute dunked in plaster of Paris.
Adapting the use of plaster of Paris for use in hospitals, however, took some time. In 1828, doctors in Berlin were treating leg fractures by aligning the bones in a long narrow box, which they filled with moist sand. Substitution of plaster of Paris for the sand was the next logical step.
The plaster is not pure plaster of Paris, but rather has additives to improve green strength, dry strength, permeability, and castability.For instance, talc or magnesium oxide are added to prevent cracking and reduce setting time; lime and cement limit expansion during baking; glass fibers increase strength; sand can be used as a filler.

[10] Fiberglass casts were introduced in the 1980s or 1990s.
The original plaster was restored in 1917 and is displayed at the Musée d'Orsay in Paris. [8] A series of plaster casts illustrating the development of the work is on view at the Musée Rodin in Meudon. Also in 1917, a model was used to make the original three bronze casts: The Musée Rodin, Paris. [10] The Rodin Museum, Philadelphia, United ...
Plaster is widely used as a support for broken bones; a bandage impregnated with plaster is moistened and then wrapped around the damaged limb, setting into a close-fitting yet easily removed tube, known as an orthopedic cast. Plaster is also used in preparation for radiotherapy when fabricating individualized immobilization shells for patients ...
A male pathologist was said to have recorded the face of an unidentified young woman who, around the age of sixteen, according to his story, had been found drowned in the River Seine at Paris, around the late 1880s. The pathologist at the Paris Morgue was so taken by her beauty that he worked for hours to make a plaster cast of her face.
