. . MEDICINE, SCIENCE. . . • a chemist and microbiologist from France, was one of the founders of medical microbiology. • Pasteur was sure that pathogens attack the body from the outside and later thought of the germ theory of disease • developed a technique for pasteurizing liquids • Developed vaccines for rabies, anthrax • after investigating an epidemic among silkworms, determined that parasites were the cause.

. . 1842: Crawford Long was the first doctor to give a patient inhale ether anesthesia for a surgical procedure. 1818: James Blundell, a British performed the first successful blood transfusion on a patient who had hemorrhaged. 1816: Rene Laennec, invented the stethoscope and pioneered its use in the diagnosis of chest infections. 1890: Emil von Behring discovered antitoxins and used them to develop vaccines for diphtheria and tetanus. He later received the first Nobel Prize in Physiology or Medicine. 1895: Wilhelm Conrad Béntgen discovered X-rays by producing and detecting electromagnetic radiation in this wavelength range..

. . 20th century 1954 Joseph Murray carried out the human kidney transplant 1959 Min Chueh Chang carried out the in vitro fertilization (IVF) that later led to the first "test tube baby" 1967 Christiaan Barnard ærried out the first human-to-human heart transplant 1979 George Hitchings and Gertrude Elion made important breakthroughs with antiviral medications, pioneering work led to the development of azidothymidine (AZT), an HIV drug. Rune Elmqvist developed the first implantable pacemaker and the first inkjet ECG printer 1958 Thomas Starzl performed the first human liver transplant while James Hardy carried out the first human lung transplant 1963 Raymond Vahan Damadian discovered the use of magnetic resonance imaging (MRI) while Godfrey Hounsfield, presented the computed tomography (CT) scan machine that he had 1971 o.

. . Modern Era • 1985: Sir Alec John Jeffreys developed the techniques for DNA fingerprinting and profiling that forensic departments now use worldwide. These techniques also resolve problems not relating to crime, such as paternity disputes. • 1986: Eli Lilly launched fluoxetine (Prozac), a selective serotonin reuptake inhibitor (SSRI) class antidepressant that doctors prescribe for several mental health problems. • 2001: Kenneth Matsumura created the first bio- artificial liver • 2005: Jean-Michel Dubernard carried out a partial face transplant on a woman whose face became disfigured as a result of a dog attack. • 2010: Spanish doctors carried out a full-face transplant on a man who had been in a shooting accident. Present: Stem cell therapy - Scientists are working on • making human tissue and even whole organs from stem cells. This technique could one day help in treatments ranging from wound healing to prosthetics and replacement livers. Present: Coronavirus vaccine due to the pandemic •.

. . Engineering 831 - The Electric Dynamo — T invention of the electric dynamo by Michael Faraday apened up the practical use of electricity — from transport to power tools and home appliances. 1877 - Phonograph — Thomas Edison found that sound could be captured and replayed using a rotating cylinder covered with paraffin paper and a stylus. 1860s - Computer — Charles Babbage's analytic engine is often seen as the forerunner the modern computer. -Lightbulb —Througho the 19th century, inventors produced simple electric lights. Joseph Swan produced a simple electric light but struggled to maintain a power source. It was Thomas Edison who made the lightbulb into a practical low current version. 1869 - Plastic — Developed by John Wesley Hyatt. He was looking for a cheap substitute to ivory billiard balls. Hyatt combined cellulose nitrate and mphor to produce a versatile material — celluloid. 1898 - Motor Car- By 1898 the German engineer Karl Benz produced the first modern automobile using a patented internal combustion engine. 1876 Telephone — The telephone was invented in 1876 by Alexander Graham Bell. Teaching by day, he spent many hours of his spare time, developing a form of telephone. 1888 — Camera — Louis Daguerre made a breakthrough with a camera which took imprints to be developed by chemicals. In 1888, George Eastman developed the first small Kodak box camera. 1903 -Aeroplane —The Wright brothers piloted the first successful heavier than air aeroplane on Dec 17th, 1903..

. . Architecture The first wire-cable suspension bridge, the 407 ft (124 m) long Spider Bridge at Falls of Schuylkill in Philadelphia, Pennsylvania, constructed by Erskine Hazard & Josiah White, opened in 1816. The first major glass building in the world, the Great Conservatory in Chatsworth, England, designed by Joseph Paxton, constructed between 1836 and 1840. It was 227 ft (69.2 m) long, 123 ft (37.5 m) wide and 67 ft (20.4 m) high. The glass house wasn't heated during WWI, and the plants died. The place was demolished in the early 1920s. The first iron-reinforced concrete structure, a four-story house in the northern suburbs of Paris, France, designed by Theodore Lachez, built by Francois Coignet • The 138 ft (42 m) high Home Insurance Building in Chicago, the first skyscraper and the first to use structural steel in its frame, designed by William Le Baron Jenney, completed in 1884. The world's first reinforced concrete skyscraper, the 15-story Ingalls Building in • Cincinnati, Ohio, designed by Elzner & Anderson and built in 1903. The first building heated primarily by solar energy: the MIT Solar House #1, built in • 1939 on the MIT campus, designed by a team led by Hoyt C. Hottel. The first commercial building with the system was the Solar Building in Albuquerque, New Mexico, built in 1956, designed by Frank Bridgers and Donald Paxton..
