Brains of other geniuses

Preserving the brains of geniuses was not a new phenomenon—another famous brain to be preserved and discussed in a similar manner was that of the German mathematician Carl Friedrich Gauss almost a hundred years earlier. His brain was studied by Rudolf Wagner who found its weight to be 1,492 grams and the cerebral area equal to 219,588 square millimeters.[9] Also found were highly developed convolutions, which was suggested as the explanation of his genius .[10] Other famous brains that were removed and studied include that of Vladimir Lenin[11] and the Native American, Ishi. The brain of Edward H. Rulloff, philologist and "criminal of superior intelligence," was removed after his death in 1871; in 1972, it was still the second largest brain on record.[12]
