Crawford Long was born in Georgia in 1815. He spent 20 years trying to become a doctor. He used Ether as an anesthetic. An anesthetic is a drug that makes you lose consciousness. This means you fall asleep and you can't see, hear, or feel. In 1842, James Simpson was inspired by ether to invent chloroform for use during childbirth.
Copies of writings used to have to be made by hand. Alexander Bain was born in Scotland in 1811. Bain invented the Fax Machine. He moved to London and combined clockmaking and electricity to make the fax machine. Fax machines scan and reproduce documents and it can transmit a page every 5 seconds over the telephone lines. An Italian developed a machine that became commercially successful around 1861.
Sailing across the high seas was dangerous. Isambard Brunel was born in England in 1806. He was an apprentice to a clockmaker. Brunel built bridges and the Great Western Railroad. Large steamships transport people and cargo long distances across the ocean. The SS Great Eastern laid the first transatlantic telegraph cable. Now they could send telegraphs over the Atlantic Ocean.
Nancy Johnson invented the hand-cranked Ice Cream machine. The ingredients in ice-cream are whipped cream, sugar, and vanilla extract. Put the ingredients together in a stainless steel container. Put that container in a wooden container. Fill that container with ice. Turn a handle until you think it's done. Then take the container out of the wooden container. Then you're done. (we're very thankful for her).
