The inventions, which made life easier

  • Over the past two centuries, many people have used their knowledge, skills, and experience in order to create a host of inventions that have made the world a much better place for us to live.
  • Here are eight paramount discoveries and innovations that have improved our standard of living and have given us the opportunity to pursue our personal and business endeavors in a more comfortable and prosperous fashion.
  • Financial Services
  • Banknote (Paper Currency): Tang Dynasty of China—7th Century
  • China is not only credited with having invented paper, but it is also generally recognized to have been the first country in the world to use paper money. The paper money system helped improve economies worldwide as it moved them away from being a barter economy of trade.
  • Healthcare
  • Vaccinations: Edward Jenner—1796
  • Edward Jenner's work is widely regarded as the foundation of immunology. Jenner is well renowned throughout the world for his innovative contribution to immunization and the ultimate eradication of smallpox.
  • Local Anesthesia: William Morton—1846
  • William Morton was one of the first individuals to demonstrate how ether could be used to remove the pain of operations. His use of anesthesia was displayed at a public demonstration to the surgeons of the Massachusetts General Hospital in Boston on Oct. 16, 1846, where John Collins Warren excised a tumor from a patient's neck. William Morton wasn't necessarily the first person who discover or invent anesthetics, but his name is most commonly referenced when speaking of the first practitioners to use the drug. In fact, for 20 years various controversies and litigation surrounded the credit for the development of anesthesia.
  • Antibiotics: Alexander Fleming—1928
  • Alexander Fleming discovered the active substance that he termed "penicillin" while working on the influenza virus. Fleming made this discovery by observing that mold had developed accidentally on a staphylococcus culture plate and that the mold had created a bacteria-free circle around itself. He was inspired to further experiment and he found that a mold culture prevented the growth of staphylococci, which verified his discovery. To this day, penicillin is used to treat a host of bacterial infections.
  • Food and Drink
  • Pasteurization: Louis Pasteur—1862
  • Louis Pasteur developed the process now known as "pasteurization," which is a process of heating food to a specific temperature for a definite length of time and then cooling it immediately in order to reduce the number of viable pathogens that may cause disease. Dairy products, canned foods, juices, syrups, water, and wines are the primary products that are pasteurized today.
  • Transportation
  • Modern Automobile: Karl Benz—1886
  • Karl Benz patented all of the processes that made the internal combustion engine feasible for use in cars. Karl Benz and his wife, Bertha Ringer Benz, were the founders of the Mercedes Benz automobile manufacturing company.
  • Energy
  • Modern Alternating Current Electrical Supply System: Nikola Tesla—1891
  • Nikola Tesla filed for seven U.S. patents in the field of polyphase alternating current motors and power transmission. Tesla's patents comprised a complete system of generators, transformers, transmission lines, motors, and lighting. Tesla is also credited with the invention of the radio, although a patent dispute with the Marconi Company that was ultimately decided by the U.S. Supreme Court brings into question if he should receive the sole credit for the radio invention.
  • Technology
  • Electronic Digital Computer: John Atanasoff and Clifford Berry—1937
  • John Atanasoff and Clifford Berry constructed the first electronic computer with vacuum tubes while working for Iowa State College. The Atanasoff-Berry computer was the first digital computer. It introduced the concepts of binary arithmetic, regenerative memory, and logic circuits. The Atanasoff-Berry machine never reached the production stage and remained a prototype.
