Two days after I arrived in New York, I found a place to live. It was large enough for me to use one of the rooms as my laboratory. I filled this room with expensive scientific equipment that I did not know how to use. But by the end of my first year in the city, I had become an expert with the microscope. I also had become more and more unhappy. The lens in my expensive microscope was still not strong enough to answer my questions about life. I imagined there were still secrets in Nature that the limited power of my equipment prevented me from knowing. I lay awake nights, wishing to find the perfect lens – an instrument of great magnifying power. Such a lens would permit me to see life in the smallest parts of its development. I was sure that a powerful lens like that could be built. And I spent my second year in New York trying to create it. I experimented with every kind of material. I tried simple glass, crystal and even precious stones. But I always found myself back where I started. My parents were angry at the lack of progress in my medical studies. I had not gone to one class since arriving in New York. Also, I had spent a lot of money on my experiments. One day, while I was working in my laboratory, Jules Simon knocked at my door. He lived in the apartment just above mine. I knew he loved jewelry, expensive clothing and good living. There was something mysterious about him, too. He always had something to sell: a painting, a rare statue, an expensive pair of lamps. I never understood why Simon did this. He didn't seem to need the money. He had many friends among the best families of New York.
