Many years ago nobody knew about chloroform. And when the doctor operated on a patient, the patient suffered great pain. A young doctor in Edinburgh could not see how patients suffered during operations and he tried to find some medicine to help the patient to overcome the pain. The doctor's name was James Simpson.

Once he came home from the hospital with two other doctors. When he was looking for some papers on his desk he saw a little bottle. He remembered that one of his friends had sent him a bottle with chloroform. At that time people knew very little about chloroform.

James Simpson opened the bottle. Chloroform had a strong but not an unpleasant smell. He decided to breathe chloroform in and see a result. The two doctors who were in the room decided to do the same. And so they did. As they breathed in the chloroform they became sleepy and soon they fell into a deep sleep.

After the experiment Dr. Simpson began to use chloroform during his operations. It was a very important discovery. Doctors could operate on the people without hurting them and it was easier for the surgeon to operate because the patients were calm and did not move during the operation.
