He had always been interested in this subject. As a ten-year old boy itself he had a chemical laboratory in his house. As he was not very well off financially, he sold candy and newspapers in the trains. This was not enough .when he grew older he bought an old printing press and began printing newspapers in the luggage car of the train. He also had his laboratory along with the printing press.
