There had been many diffrent types of cameras in history but i will be focusing on the one that Robert Boyle had made.

The cell theory was first found in the year 1665 by the man named Robert Hook.

After many investagations he had found that animals were made up of cells as well.

In this time in WW1 the Germans had used mustard gas as chemical warfare but then at the University of Yale had found that if you inject it into the blood stream that the substance rapidly made white blood cells, so in doing so they had came up with a idea that if they injected this into people with cancer the white blood cells whould kill off the cancer cells. And that is when chemotherapy was born.
