Various sites speculate over the exact date of his death, but most agree that it was on October 21st (or the 18th) 1931. I have a copy of a telegram from Edison's attending physician, Dr. Hubert S. Howe stating that Thomas Alva Edison quietly passed away at 3:24 am on October 18, 1931. He died at his home, now part of the National Park Service, in Llewellyn Park, West Orange, NJ.
He never did. Indeed, Edison did not do any work with electric calculators. Others invented mechanical devices that could do calculations, but these were (literally) one of a kind. Not until 1851 was a calculator sold on a large-scale basis, and even then only a few thousand were sold in the next half century. Note that, the item "Edison Cordless Calculator Patent 1902" is a joke item from the 1960s that only uses that name and date for humor.
