His father, Samuel Edison, was of Dutch ancestry and his mother, Nancy Elliot, was of English descent.
Thomas Edison was born in Milan, Ohio, United States, on February 11, 1847. He was the seventh and last child of Samuel Ogden Edison Jr. and Nancy Matthews Elliott. His father was an exiled political activist from Canada, while his mother was an accomplished school teacher and a major influence in Thomas’ early life.
At an early age, Edison developed hearing problems, which have been variously attributed but were most likely due to a familial tendency to mastoiditis. Whatever the cause, Edison’s deafness strongly influenced his behaviour and career, providing the motivation for many of his inventions.
