Thomas 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.
