Hideyo Noguchi

Hideyo Noguchi , also known as Seisaku Noguchi , was a prominent Japanese bacteriologist who in 1911 discovered the agent of syphilis as the cause of progressive paralytic disease.

Noguchi Hideyo was born in Inawashiro, Fukushima prefecture in 1876. When he was one and a half years old, he fell into a fireplace and suffered a burn injury on his left hand. There was no doctor in the small village, but one of the men examined the boy. The fingers of the left hand are mostly gone, he said, and the left arm, the left foot, and the right hand are burned I dont know how badly.
