History
Greek physician Herophilus, the “father of anatomy”, lived in 300 BC in Alexandria, Egypt. He was the first physician on record to have dissected bodies.
The tradition of dissecting criminals was carried up into the eighteenth and nineteenth century when anatomy schools became popular in England and Scotland. At that time, a greater percentage of Christians believed in the literal raising from the dead. Because the souls of dissected bodies could not go to heaven, people rarely offered their bodies to science. Criminals who were executed for their crimes were used as the first cadavers. The demand for cadavers increased when the number of criminals being executed decreased. Since corpses were in such high demand, it became commonplace to steal bodies from graves in order to keep the market supplied.
The methods of preserving cadavers have changed over the last 200 years. At that time, cadavers had to be used immediately because there were no adequate methods to keep the body from quickly decaying. Preservation was needed in order to carry out classes and lessons about the human body. Glutaraldehyde was the first main chemical used for embalming and preserving the body although leaves a yellow stain in the tissues, which can interfere with observation and research.
Formaldehyde is the chemical that is used as the main embalming chemical now. It is a colorless solution that maintains the tissue in its lifelike texture and can keep the body well preserved for an extended period.

Famous quotes containing the word history:
“... in a history of spiritual rupture, a social compact built on fantasy and collective secrets, poetry becomes more necessary than ever: it keeps the underground aquifers flowing; it is the liquid voice that can wear through stone.”
—Adrienne Rich (b. 1929)
“In history as in human life, regret does not bring back a lost moment and a thousand years will not recover something lost in a single hour.”
—Stefan Zweig (18811942)
“When the coherence of the parts of a stone, or even that composition of parts which renders it extended; when these familiar objects, I say, are so inexplicable, and contain circumstances so repugnant and contradictory; with what assurance can we decide concerning the origin of worlds, or trace their history from eternity to eternity?”
—David Hume (1711–1776)
