Who Was a Greater inventor Leonardo Da Vinci Or Thomas Edison
Transcript of Who Was a Greater inventor Leonardo Da Vinci Or Thomas Edison
1452–1466 Leonardo was born on April 15, 1452, "at the third hour of the night" in the Tuscan hill town of Vinci, in the lower valley of the Arno River in the territory of Florence. He was the illegitimate son of Messer Piero Fruosino di Antonio da Vinci, a Florentine notary, and Caterina, a peasant who may have been a slave from the Middle East. Leonardo had no surname in the modern sense, "da Vinci" simply meaning "of Vinci": his full birth name was "Leonardo di ser Piero da Vinci", meaning "Leonardo, son of (Mes)ser Piero from Vin Humble begginings. Born out of wedlock, the love child of a respected notary and a young peasant woman, Leonardo da Vinci (b. April 15, 1452, in Vinci, Italy) was raised by his father, Ser Piero, and his stepmothers. At the age of 14, Leonardo began apprenticing with the artist Verrocchio. For six years, he learned a wide breadth of technical skills, including metalworking, leather arts, Meteoric Rise In 1482, Lorenzo de’ Medici, a man from a prominent Italian family, commissioned Leonardo to create a silver lyre and bring it to Ludovico il Moro, the Duke of Milan, as a gesture of peace. Leonardo did so and then wrote Ludovico a letter describing how his engineering and artistic talents would be of great service to Ludovico’s court. His letter successfully endeared him to Ludovico, and from 1482 until 1499, Leonardo was commissioned to work on a great many projects. It was during this time that he painted The Last Supper. Leonardo’s most well-known painting, arguably the most famous painting in the world, the Mona Lisa, was a privately commissioned work and was completed sometime between 1505 and 1507. Renaissance Man His drawings of a fetus in utero, the heart and vascular system, sex organs, and other bone and muscular structures, are some of the first on human record. One of his last commissioned works was a mechanical lion that could walk and open its chest to reveal a bouquet of lilies. On May 2, 1519, Leonardo’s first assistant and perhaps his lover, Francesco Melzi, became the principal heir and executor of his estate. Thomas edison Thomas Alva Edison was born on February 11, 1847 in Milan, Ohio; the seventh and last child of Samuel and Nancy Edison. When Edison was seven his family moved to Port Huron, Michigan. Edison lived here until he struck out on his own at the age of sixteen. Edison had very little formal education as a child, attending school only for a few months. He was taught reading, writing, and arithmetic by his mother, but was always a very curious child and taught himself much by reading on his own. This belief in self-improvement remained throughout his life. Edison as a child Edison began working at an early age, as most boys did at the time. At thirteen he took a job as a newsboy, selling newspapers and candy on the local railroad that ran through Port Huron to Detroit. He seems to have spent much of his free time reading scientific, and technical books, and also had the opportunity at this time to learn how to operate a telegraph. By the time he was sixteen, Edison was proficient enough to work as a telegrapher full time. First Patent The development of the telegraph was the first step in the communication revolution, and the telegraph industry expanded rapidly in the second half of the 19th century. This rapid growth gave Edison and others like him a chance to travel, see the country, and gain experience. Edison worked in a number of cities throughout the United States before arriving in Boston in 1868. Here Edison began to change his profession from telegrapher to inventor. He received his first patent on an electric vote recorder, a device intended for use by elected bodies such as Congress to speed the voting process. This invention was a commercial failure. Edison resolved that in the future he would only invent things that he was certain the public Inventions The first great invention developed by Edison in Menlo Park was the tin foil phonograph. The first machine that could record and reproduce sound created a sensation and brought Edison international fame. Edison toured the country with the tin foil phonograph, and was invited to the White House to demonstrate it to President Rutherford B. Hayes in April 1878. The first great invention developed by Edison in Menlo Park was the tin foil phonograph. Thomas Edison's greatest challenge was the development of a practical incandescent, electric light. Contrary to popular belief, he didn't "invent" the lightbulb, but rather he improved upon a 50-year-old idea. In 1879, using lower current electricity Thomas Edison's interest in motion pictures began before 1888, however, the visit of Eadweard Muybridge to his laboratory in West Orange in February of that year certainly stimulated his resolve to invent a camera for motion pictures.
