The brain of Albert Einstein has been a subject of much research and speculation. Einstein, a renowned theoretical physicist, is best known for his theory of relativity and contributions to the understanding of quantum mechanics. Upon his death in 1955, his brain was removed and preserved for scientific study.

Removal and Preservation

After Einstein's death on April 18, 1955, at the age of 76, his brain was removed by Thomas Stoltz Harvey, the pathologist who conducted the autopsy at Princeton Hospital. Harvey took the brain without the permission of Einstein's family, which later led to controversy. The brain was preserved in formalin and sectioned into 240 blocks, which were then further sliced into microscopic sections.

Studies and Findings

Over the years, various studies have been conducted on Einstein's brain to understand the source of his intellectual capabilities. Some of the notable findings include:

• **Parietal Lobes**: Studies have shown that Einstein's parietal lobes, which are responsible for spatial and mathematical reasoning, were 15% wider than those of a typical brain.
• **Sylvian Fissure**: The Sylvian fissure in Einstein's brain was partially absent, which might have allowed for more connections between neurons in this region.
• **Glial Cells**: Research indicated a higher ratio of glial cells to neurons in certain areas of Einstein's brain, suggesting enhanced metabolic support for neurons.

Controversies and Ethical Issues

The removal and study of Einstein's brain have raised several ethical questions. The lack of consent from Einstein or his family has been a significant point of contention. Additionally, the scientific community has debated the validity and significance of the findings, with some arguing that the differences observed in Einstein's brain may not necessarily correlate with his intellectual abilities.

Current Location

Parts of Einstein's brain are held at the Mütter Museum in Philadelphia, while other sections are stored at the National Museum of Health and Medicine in Washington, D.C.. Some slides and sections have also been distributed to various researchers and institutions around the world.
