Postal System1497 Franz von TaxisHenry BishopRowland HillWilliam Dockwra Franz von Taxis created the postal system, with regular routes between far-flung cities throughout Europe. Eventually, von Taxis mail routes included mail delivery between Brussels and: Innsbruck, 5.5 days (6.5 days winter) Paris, 44 hours (54 hours winter) Blois, 2.5 days (3 days winter) Lyon, 4 days (5 … Continue reading "Postal System"
AirplaneWilbur and Orville Wright invented the airplane with their first flight in 1903. Urban myth describes an easy story where the bicycle mechanic brothers built an airplane from spare parts. In reality, the innovation was a long, slow, methodical, and extremely dangerous project. Background People had been building various forms of fixed-wing gliders for years. … Continue reading "Airplane"
SmartphoneIn 1909, Nicola Tesla described what eventually would be a smartphone. They’ve existed in various forms for many years. History IBM invented a phone called the Angler in 1992 with PDA like functions. Subsequently, they released a commercial version in 1994. The term “smartphone” first appears in 1995 describing AT&T’s PhoneWriter Communicator. Eventually, more phones … Continue reading "Smartphone"
Frozen FoodFather of frozen food Clarence “Bob” “Bugs” Birdseye was first and foremost a naturalist. Birdseye collected countless insects, opened a taxidermy service in his teens, and worked at the United States Agriculture Department through his early years. While working with the Inuit in Canada he learned that fish in -40C weather would almost instantly freeze … Continue reading "Frozen Food"
Portable ComputerPortable computers are more convenient than stationary computers. They increase productivity for people who travel, allow office workers to bring work home, and enable telecommuting. Background Portable computers were developed at (where else), Xerox PARC. The Xerox NoteTaker, released in 1978, was the first portable computer. Staying true to Xerox tradition, only about ten were … Continue reading "Portable Computer"
Dry Cell BatteryDry cell batteries are the batteries the world is familiar with, the one’s that run portable electronics. Voltaic pile batteries, that preceded dry-cell batteries, required constant maintenance. Background To contextualize this era, the telegraph was gaining widespread adoption. However, there was no power grid to run the telegraphs at this time. The first power plant, … Continue reading "Dry Cell Battery"
TypewriterTypewriters vastly lower the cost of producing readable text. Before the typewriter people would have to either write carefully (slowly) or hire a calligrapher. Mill patented the first typewriter in 1714. Nothing more is known about him; he has disappeared into history. Christopher Sholes invented the QWERTY keyboard and typewriter ー the first commercially successful … Continue reading "Typewriter"
Laser PrinterLaser printing is the only Xerox research project to generate significant revenue and profit for the company. However, it predates PARC. Subsequently, most Xerox laser printing revenue came from licensing the technology to other firms. Despite their success in the enterprise market and strong brand Xerox never built a widely used Xerox-brand laser printer. Background … Continue reading "Laser Printer"
Ted Hoff’s General Purpose Microprocessor“…even though science and technology are wonderful, what really gets them out there for people to use is to have businesses built around them. It takes savvy businessmen as well as savvy technologists to make that work.” Tedd Hoff Background Ted Hoff had access to then state-of-the-art vacuum tube circuits in high school. In 1954, … Continue reading "Ted Hoff’s General Purpose Microprocessor"
Modern Computer Programming LanguagesEarly computers were programmed by literally connecting wires then turning the machine on. Eventually, that evolved to assembly language; a one and zero type exercise telling the computer exactly what to do. Modern computer programming languages are more like English. Programmers write in an English-like language and a computer program turns that into the ones … Continue reading "Modern Computer Programming Languages"
Rechargeable Battery1859 Frenchman Gaston Planté invented the lead-acid rechargeable battery. In the early years, his battery lacked commercial value. Planté’s battery stored electricity and recharged easily but tended to release the electric in enormous bursts that, at the time, offered limited utility value. Before the Planté battery was the Voltaic Pile and later derivatives. These were … Continue reading "Rechargeable Battery"
Internal Combustion EngineFew innovations throughout history are as important as the internal combustion engine. In 1807, the Niepce brothers received a patent on an internal combustion engine but failed to commercialize it. The brothers also invented photography. The first known working internal combustion engine (ICE) belongs to Lenoir. He converted a steam engine to burn coal gas … Continue reading "Internal Combustion Engine"
Instant MessagingSending instant messages by computer is fun and convenient. Moreover, text chatting is asynchronous, unlike voice or video. Accordingly, people need not communicate in real-time. Surprisingly, text messaging became extremely popular. The earliest instant messaging system designed for that purpose was “Talkomatic” and “term-talk” for the PLATO system. College students David Wooley and Doug Brown … Continue reading "Instant Messaging"
Combine HarvesterBackground Before the combine harvester farmers would need to hire groups of people to harvest crops before they rotted. Since there were only so many people available, the ability to harvest limited the volume of crops that could be grown. The harvester fixed that, doing the work of many people at once. This enabled the … Continue reading "Combine Harvester"
LaparoscopyFor centuries surgeons have been purposefully cutting holes in people trying to heal them. Background Before anesthesia, antibiotics, and Lister’s germ theories surgery often meant a slow and painful death from infection. Putting things into perspective, more people died in the US Civil War from infection than from direct strike of a weapon. Purposefully cutting … Continue reading "Laparoscopy"
