Federick William Herschel was the inventor of the Hersinian telescope. He invented this in his backyard with his sister Caroline while discovering an odd shaped star in the sky looking threw a Newtonian telescope.
The first known method of artificial refrigeration was demonstrated by William Cullen at the University of Glasgow in Scotland in 1748. Cullen used a pump to create a partial vacuum over a container of diethyl ether, which then boiled , absorbing heat from the surrounding air. The experiment even created a small amount of ice, but had no practical application at that time. ~From Wikipedia- Refrigeration
