He was provided room and board and six weeks each year of schooling in return for service in his master's shop  He was an American blacksmith who lived in Vermont. He later m oved to New York City and published a journal on electromagnetism. Thomas Davenport invented the electric streetcar in 1834 This was a big help to people. People were now able to get around by streetcar instead of walking or using horses. It enabled people to get to places in shorter amounts of time. The streetcar replaced horse drawn wagons and people walking from place to place.

<span style="font-size: 95%; font-family: Georgia,serif;">Samuel Morse <span style="font-size: 95%; font-family: Georgia,serif;">Samuel Morse invented the Electric Telegraph <span style="font-size: 95%; font-family: Georgia,serif;">On April 17, 1791, Samuel Finley Breese Morse was born in Charlestown, Massachusetts. His father was a Congregational Minister. In 1805 he goes to Yale College at the age of 14. While at Yale, he attends lectures on electricity given by Benjamin Silliman and Jeremiah Day. He earned his money by painting small portraits of friends, classmates and teachers. <span style="font-size: 95%; font-family: Georgia,serif;">Samuel Morse successfully exploited the electromagnet and bettered the telegraph systems which were invented by Joseph Henry, Charles Weatstone and William Cooke. Samuel Morse, who invented the Morse Code by using pulses of current to deflect an electromagnet, which also moved a market to produce written codes on a strip of paper. This was done while he was a professor of arts and design at New York University in 1935. But, it was in 1936 the devise was modified to emboss the paper with dots and dashes. <span style="font-size: 95%; font-family: Georgia,serif;">This was a means of communications. An experimental line was constructed from Washington to Baltimore, approximately 40 miles. This experiment was very useful to all people in order to communicate to others far away. <span style="font-size: 95%; font-family: Georgia,serif;"> There were different versions of the telegraph, but this was the more advanced. No other device was able to act as a means of communication from such a distance.

<span style="font-size: 95%; font-family: Georgia,serif;">John Gorrie > <span style="font-size: 95%; font-family: Georgia,serif;">Refrigerator <span style="font-size: 95%; font-family: Georgia,serif;">John Gorrie was born on October 3, 1802 in Charleston, South Carolina. In 1825 he enrolled in the College of Physicians and Surgeons. In 1827 he got his medical degree. IN 1845, Gorrie had completely abandoned his medical practice to concentrate on his invention. <span style="font-size: 95%; font-family: Georgia,serif;">In 1841 there was an epidemic of malaria and yellow fever. Gorrie dedicated his time to finding a cure for these diseases. At the onset of malaria, it brought violent shakes and chills, followed by high fever and terrible sweats. The yellow fever started out with a high fever. With these types of symptoms, he tried to figure out a way to control the temperature of the patents body and the humidity of the room. At this time ice was a rare commodity. Between 1837 and 1845, he developed an ice machine. This machine compressed air in a chamber. The air was then released to expand rapidly, causing it to absorb the heat from water that surrounded the chamber. The compressed air drew enough heat away from the water to bring the water temperature down below freezing, thus creating ice. In 1845, he finalized the design of his ice machine. In 1848 he commissioned the Cincinnati Iron Works to build a working model, which Gorrie began demonstrating the ability of his Ice Machine. <span style="font-size: 95%; font-family: Georgia,serif;">Many people got sick and died from food that was not stored properly. Plus, like noted above, this ice machine was used to produce ice in order to help sick people to keep fevers down. <span style="font-size: 95%; font-family: Georgia,serif;"> Ice was a rare commodity. At that time, ice was harvested from mountains or frozen lakes and stored in large insulated warehouses. This made it possible f or people to have easy access to ice for any reason.

He was seventh and last child of Samuel and Nancy Edison. The family moved to Port Huron, Michigan. Thomas, who had very little education, and struck out on his own at the age of sixteen. <span style="font-size: 95%; font-family: Georgia,serif;">He invented the light bulb on October 22, 1879 <span style="font-size: 95%; font-family: Georgia,serif;">At that time, people were carrying around candles and had open flames for lighting. The light bulb was a great invention. There were minimal fires or accidents due to fires with the light bulb in use instead of open torches. <span style="font-size: 95%; font-family: Georgia,serif;">The light bulb replaced open flames, like candles, for lighting. <span style="font-size: 95%; font-family: Georgia,serif;">
