Einstein's brain was removed, weighed and preserved by Thomas Stoltz Harvey, the pathologist who performed the autopsy on Einstein. He claimed he hoped that cytoarchitectonics would reveal useful information.
Harvey injected 10% formalin through the internal carotid arteries and afterwards suspended the intact brain in 10% formalin. Harvey photographed the brain from many angles. He then dissected it into roughly 240 blocks (each about 10cm3) and encased the segments in a plastic-like material called celloidin.
