AirshipSporting both bodacious name, mustache, and title of nobility, Count Ferdinand von Zeppelin forever changed air travel. Zeppelin wasn’t the first to try making hot air balloons more maneuverable. That honor belonged to Frenchman Henri Giffard. Basically, a big cigar-shaped balloon, Giffard’s airship was the first aircraft that enabled navigation. In 1882, with declining health, … Continue reading "Airship"
AirlineCount von Zeppelin, inventor of the airship, partnered with a group of other German industrialists to create a Zeppelin manufacturing company and also an airline. Airships Their first airship, the enormous LZ1, launched July 2, 1900. It crashed and survived but the test was not successful for the German government to invest more funds in … Continue reading "Airline"
DynamiteDynamite blows up otherwise difficult to move things, like boulders, mountains, and bedrock. It lowers the cost of removing rocks to make level land and tunnels, railroads, roads, and enables foundations for skyscrapers. In 1847 chemists Théophile-Jules Pelouze and Ascanio Sobrero had synthesized nitroglycerin but the chemical was unstable and difficult to harness. Nobel encased … Continue reading "Dynamite"
MimeographMimeographs are essentially low-cost but low-quality and easy-to-use printing presses. They produced good-enough copies at a cost far lower than hand copying. Copies are produced from user-created stencils. Mimeographs remained the dominant form of document duplication for almost a century until photocopy machines became inexpensive and ubiquitous. For decades, mimeographs were the only way to … Continue reading "Mimeograph"
Transistor RadioDeveloped in 1947 but commercialized in 1954, transistor radios are small. Battery-operated portable radios that fit in a pocket. They rely on transistors rather than vacuum tubes. There were several attempts to build radios with transistors but none were optimal until 1954. Eventually, a Texas Instruments team invented the Regency TR-1, the first radio miniaturized … Continue reading "Transistor Radio"
Vacuum Tube (Diode)Working for the Edison Electrical Light Company of England, Sir John Fleming invented the diode, a vacuum tube at the heart of all early electronics. Radios, television, telephones, computers – virtually every electronic we’re familiar with today – was first built with diodes. Diodes are typically vacuum tubes, though some have specialized gasses in them. … Continue reading "Vacuum Tube (Diode)"
Automation: Robots in Real LifePart I, “Automation Armageddon: a Legitimate Worry?” reviewed the history of automation, focused on projections of gloom-and-doom. “It smells like death,” is how a friend of mine described a nearby chain grocery store. He tends to exaggerate and visiting France admittedly brings about strong feelings of passion. Anyway, the only reason we go there is … Continue reading "Automation: Robots in Real Life"
Personal Digital Assistant (PDA)Personal Digital Assistants (PDAs) are handheld computers. They were supposed to be more convenient and simpler than carrying paper. Most significantly, and the reason they are a major invention, is their influence as a bridge to the smartphone. David Potter created the Psion Organizer in 1984 featuring 2K or RAM in a handheld (sort of … Continue reading "Personal Digital Assistant (PDA)"
Stock IndexStock indexes set objective benchmarks for how a stock should perform against peers. Reduces the risk of stock investing. Farmer turned reporter turned media mogul Charles Dow, with reporter Edward Jones, launched a stock newsletter in 1883. Titled the Customers’ Afternoon Letter, they tracked issues affecting the stock market. Dow’s letter gained a reputation for … Continue reading "Stock Index"
Core MemoryCore memory enhanced the productivity of early computer operators. Not only does core memory store information but also does not need power to maintain memory. Wang & Woo created computer memory that would sit on tiny magnetic rings, strung together into cores. These were smaller than vacuum tubes and used less power. Furthermore, they did … Continue reading "Core Memory"
Plasma Panel1964 Donald BitzerGene SlottowRobert Wilson Plasma panels form fonts, images, and other patterns using plasma, rather than tubes. The panels are flat, cool, and use less power than CRT tubes. Bitzer developed the plasma panel as the monitor for his teaching computer, PLATO. PLATO is a lesser-known fountain of innovation. Along with Bell Labs, Xerox … Continue reading "Plasma Panel"
Compact Audiotape CassetteIn 1960, Consumer Reports reviewed an in-car vinyl record player offered by Chrysler, The RCA Victor “Victrola.” It held 14 records and could play for 2.5 hours continuously. To keep the needle from bouncing around, it was pressed into the vinyl wearing down records. Despite that common sense says the invention sounds idiotic, it worked … Continue reading "Compact Audiotape Cassette"
Overnight MailFedEx is the first overnight mail delivery service. At the time, the idea was widely derided. Before FedEx, the only way to reliably deliver a package quickly was via overnight courier, an extremely expensive option. In 1965, Yale undergrad student Fred Smith wrote a paper describing the idea as an undergraduate in Yale. Smith reasoned … Continue reading "Overnight Mail"
Franchising & Cross-MarketingBefore McDonald’s King Ray Kroc was born Martha Harper built an enormous franchise empire. At a time few women worked in business, much less founded and owned them, she developed two vital strategic moves. Harper created cross-marketing, the concept where that stores with one purpose can sell related products. Specifically, she created hair salons to … Continue reading "Franchising & Cross-Marketing"
Steam Engine (Newcomen)The Newcomen steam engine removed water from mines. It worked but was extremely inefficient. Steam was not recycled (re-condensed) so the Newcomen engine required an enormous amount of coal to continually boil water. When used at a coal mine, where scrap coal was essentially free, this cost less than having workers remove water by the … Continue reading "Steam Engine (Newcomen)"
