>>13467771Thomas Edison was born in 1847 in Milan, Ohio, but grew up in Port Huron, Michigan, after the family moved there in 1854.[7] He was the seventh and last child of Samuel Ogden Edison Jr. (1804–1896, born in Marshalltown, Nova Scotia) and Nancy Matthews Elliott (1810–1871, born in Chenango County, New York State).[8][9] His patrilineal family line was Dutch by way of New Jersey;[10] the surname had originally been "Edeson".[11]
Edison was taught reading, writing, and arithmetic by his mother who used to be a school teacher. He attended school for only a few months. However, one biographer described him as a very curious child who learned most things by reading on his own.[12] As a child, he became fascinated with technology and spent hours working on experiments at home.[13]
Edison developed hearing problems at the age of 12. The cause of his deafness has been attributed to a bout of scarlet fever during childhood and recurring untreated middle-ear infections. He subsequently concocted elaborate fictitious stories about the cause of his deafness.[14] Being completely deaf in one ear and barely hearing in the other, it is alleged that Edison would listen to a music player or piano by clamping his teeth into the wood to absorb the sound waves into his skull.[15] As he got older, Edison believed his hearing loss allowed him to avoid distraction and concentrate more easily on his work.
