WebSpice Services DeMorgan Augustus De Morgan (1806 - 1871) Augustus De Morgan was a brilliant mathematician and professor noted for his advances in algebra and logic. He was a friend of Charles Babbage (inventor of the Analytical Engine, forerunner of the modern computer) and he tutored Ada Lovelace, who was the poet Lord Byron's daughter and supposedly wrote the first computer program for Babbage's machine. De Morgan was prolific and wrote such mathematical texts as Elements of Arithmetic Penny Cyclopedia (1838) where he coined the term 'mathematical induction', Trigonometry and Double Algebra (1849), a geometric interpretation of complex numbers, and Formal Logic (1847), one of his most important works. De Morgan was an uncompromising advocate of religious liberty and free expression; while at Trinity College he would not sign required theological forms and was therefore not allowed to continue with his graduate eduation and fellowship. He was a founder, with George Boole, of symbolic logic as it developed in England. He wrote many books and articles, including Trigonometry and Double Algebra and Formal Logic. He is perhaps best known as the creator of De Morgan's Laws: NOT (A AND B) = (NOT A) OR (NOT B) NOT (A OR B) = (NOT A) AND (NOT B) These statements show that negating an AND makes it an OR and vice-versa. These laws have become some of the most frequently applied in modern proof theory and are widely used in software programming as well.

Life Long Learning Reading room University Community Colleges ... Grades preK to 5 GARRETT AUGUSTUS MORGAN Garrett Augustus Morgan, was an African-American businessman and inventor whose curiosity and innovation led to the development of many useful and helpful products. A practical man of humble beginnings, Morgan devoted his life to creating things that made the lives of other people safer and more convenient. Among his inventions was an early traffic signal, that greatly improved safety on America's streets and roadways. Indeed, Morgan's technology was the basis for modern traffic signal systems and was an early example of what we know today as Intelligent Transportation Systems. The Inventor's Early Life . The son of former slaves, Garrett A. Morgan was born in Paris, Kentucky on March 4, 1877. His early childhood was spent attending school and working on the family farm with his brothers and sisters. While still a teenager, he left Kentucky and moved north to Cincinnati, Ohio in search of opportunity. Although Morgan's formal education never took him beyond elementary school, he hired a tutor while living in Cincinnati and continued his studies in English grammar.

Garrett Augustus Morgan Born: March 4, 1877 Died: August 27, 1963 Birthplace: Paris, Kentucky Garrett Augustus Morgan: Traffic Engineer Garrett Augustus Morgan was born in Paris, Kentucky on March 4, 1877. Garrett Morgan received wide recognition for his outstanding contributions to public safety. Firefighters in many cities in the early 1900's wore the safety helmet and gas mask that he invented, and for which he was awarded a gold medal at the Second International Exposition of Safety and Sanitation in New York in 1914. The gas mask Morgan invented in 1912 ( U.S. 1,113,675 issued in 1914) was during World War I to protect soldiers from chlorine gas fumes. In 1916, Mr. Morgan used his own mask design to rescue men trapped by a gas explosion in a tunnel being constructed under Lake Erie. Following disaster, which killed twenty-one people, the City of Cleveland, Ohio honored Garrett Morgan with a gold medal for his heroic efforts. In 1923, Morgan received a patent for his new concept ( U.S. 1,475,024

His education never went beyond elementary school, so he decided to hire a tutor while living in Cincinnati where he worked as a handyman for a wealthy landowner. He wanted to continue his studies in English grammar. Morgan moved to Cleveland, Ohio, in 1895 working for a clothing manufacturer as a sewing machine repairman. During his employment as a repairman, he invented a belt fastener for the sewing machine. bodyOffer(19849) He truly became a businessman in 1907 with the opening of his own sewing equipment and repair shop. He included a tailoring shop in 1909 that employed 32 employees. Morgans new company began to put on the market coats, suits, and dresses. These clothes were made with the equipment that Morgan himself had made.
