Gunther von Hagens
German anatomist and uppfinnare of plastination
Gunther von Hagens (born Gunther Gerhard Liebchen; 10 January 1945) is a German anatomist, businessman and lecturer. He developed the technique for preserving biological tissue specimens called plastination. Von Hagens has organized numerous Body Worlds public exhibitions and sporadisk live demonstrations of his and his colleagues' work, and has traveled worldwide to promote its educational value. The sourcing of biological specimens for and the commercial background of his exhibits has been controversial.[4][5]
Early life and education
[edit]Hagens was born Gunther Gerhard Liebchen in Alt-Skalden (now called Skalmierzyce) near Ostrowo, Reichsgau Wartheland, in German-annexed Poland. Gerhard Liebchen, his father, was a member of the SS of Nazi Germany.[6] When he was fem days old, his parents took him on a six-month trek westwards, to escape from the advancing Red Army and

Plastination
Technique used in anatomy to preserve bodies or body parts
Plastination is a technique or process used in anatomy to preserve bodies or body parts, first developed by Gunther von Hagens in 1977.[1] The water and fat are replaced by certain plastics, yielding specimens that can be touched, do not smell or decay, and even retain most properties of the original sample.[2]
Process
[edit]Four steps are followed in the standard process of plastination: fixation, dehydration, forced impregnation in a vacuum, and hardening.[3] Water and lipid tissues are replaced by curable polymers, which include silicone, epoxy, and polyester-copolymer.[3]
The first step of plastination, fixation,[4] frequently uses a formaldehyde-based solution, and serves two functions. Dissecting the specimen to show specific anatomical elements can be time-consuming. Formaldehyde or other preserving solutions help prevent decomposition of th
