Gisella's School

This week in history I learned about rotary printing, kerosene, antiseptics, and the gas mask.

            The first thing I learned about this week was rotary printing. the rotary printing press was invented by a man named Richard Hoe. Richard didn’t really invent t printing he just improved on it like other inventors. The rotary press places the type on the rotating drum to make the printing process continuous and fast. The press was adopted immediately by the Baltimore Sun and spread to other companies as well.

            The Second thing I learned about was kerosene. Kerosene was originally lost to history before being rediscovered in the 1800s. Abraham Gesner invented modern kerosene after becoming interested in geology while studying in England. Kerosene is a clear, stable, clean burning fuel. After the discovery of petroleum, Gesner’s patent was circumvented with in kerosene was made from oil. Rockefeller became the discovery of petroleum Gesner’s patent was made from oil. Rockefeller became the richest man in American history because of his entry info the kerosene market, which led to major historical impacts on history.

            The third thing I learned about this week was antiseptics. The use of antiseptics wasn’t understood prior the the 19^th century, and in hospitals people would die without anyone understanding why. Semmelweis invented the practice of apply in antiseptics after discovering a link between dirty hands and death. Antiseptics kill germs and prevent infection. Simmelweis reproduced his results in multiple hospitals, but the medical establishment resisted his science. the modern practice of applying antiseptics now saves thousands of lives a year.

            The fourth thing I learned about the week was the gas mask. Mining and firefighting were dangerous because of the toxic atmospheres. The gas mask was invented in 1847 for use in coal mining. It filters out particulates that contain germs and chemical vapors that can react inside your body. The use of chemical warfare by the Germans in World War 1 accelerated the spread and development of gas masks. They are used today by civilians, workers, and military professionals to help them safely do their jobs.

            The most interesting thing I learned about was antiseptics because it helped keep people alive during birth and having a wound.

            The inventions I learned about this week helped with news, lighting cleanliness in wounds, and protection from chemical vapors.
