Left hemisphere of the brain of Charles Babbage

The English mathematician Charles Babbage (1792–1871) is credited with inventing the first mechanical computer, the ‘Difference Engine’. Babbage bequeathed the brain himself and, in a letter accompanying the donation, Babbage's son Henry wrote:
"I have no objection...to the idea of preserving the brain...Please therefore do what you consider best...[T]he brain should be known as his, and disposed of in any manner which you consider most conducive to the advancement of human knowledge and the good of the human race."
The brain was described by Sir Victor Horsley in the Philosophical Transactions of the Royal Society of London, 1908.
