tell me something about Thomas Alva Edison Thanks a lot
答案
Thomas Edison was born in Milan,Ohio,and grew up in Port Huron,Michigan.He was the seventh and last child of Samuel Ogden Edison,Jr.(1804–96,born in Marshalltown,Nova Scotia,Canada) and Nancy Matthews Elliott (1810–1871,born in Chenango County,New York).[citation needed] His father had to escape from Canada because he took part in the unsuccessful Mackenzie Rebellion of 1837.[citation needed] Edison considered himself to be of Dutch ancestry.
In school,the young Edison's mind often wandered,and his teacher,the Reverend Engle,was overheard calling him "addled".This ended Edison's three months of official schooling.Edison recalled later,"My mother was the making of me.She was so true,so sure of me; and I felt I had something to live for,someone I must not disappoint." His mother homeschooled him.[4] Much of his education came from reading R.G.Parker's School of Natural Philosophy and The Cooper Union.
Edison developed hearing problems at an early age.The cause of his deafness has been attributed to a bout of scarlet fever during childhood and recurring untreated middle-ear infections.Around the middle of his career Edison attributed the hearing impairment to being struck on the ears by a train conductor when his chemical laboratory in a boxcar caught fire and he was thrown off the train in Smiths Creek,Michigan,along with his apparatus and chemicals.In his later years he modified the story to say the injury occurred when the conductor,in helping him onto a moving train,lifted him by the ears.
Edison's family was forced to move to Port Huron,Michigan,when the railroad bypassed Milan in 1854,but his life there was bittersweet.He sold candy and newspapers on trains running from Port Huron to Detroit,and he sold vegetables to supplement his income.This began Edison's long streak of entrepreneurial ventures as he discovered his talents as a businessman.These talents eventually led him to found 14 companies,including General Electric,which is still in existence as one of the largest publicly traded companies in the world
