Braille Writing1829 Louis BrailleCharles Barbier Most of the innovations on Innowiki are for-profit inventions. While it could be argued that Braille’s writing technique opened new markets, the size of that market was limited to blind people. However, the impact of the innovation — a process enabling the disabled to regain one of the most important human … Continue reading "Braille Writing"
Linotype MachineThe Linotype machine vastly reduced the cost and time needed to prepare printing plates, making newspapers and books faster and less expensive to print. Described as “the next Gutenberg,” Germany immigrant Ottmar Mergenthaler made typesetting vastly simpler. Whereas before his innovation typesetters would have to look for individual letters, arranging them together, his innovation did … Continue reading "Linotype Machine"
Rock & Roll“If you’re not doing something different, you’re not doing anything.” Sam Phillips Background Billboard magazine started charting songs in 1940. Eventually, they divided songs into three categories, pop, country-and-western, and “race music.” Around 1949, race music was renamed rhythm and blues (R&B). Music sales were proprietary and closely guarded so Billboard based their charts off … Continue reading "Rock & Roll"
Moldboard PlowTraditional plows would become gunked-up with soil, forcing farmers to repeatedly stop and clear away soil. Moldboard plows repel soil, lowering the cost of farming. John Deere was an ordinary blacksmith, creating pitchforks and other common farm instruments. Farmers complained about the time wasted stopping and clearing their plows. Deere thought there must be a … Continue reading "Moldboard Plow"
RadioEarly radio transmitted Morse code over the air, not sound. Transmitting Morse Code was much less expensive than wired lines. In the mid 1880’s Heinrich Hertz published the results of experiments proving an ability to transmit electromagnetic waves, later known as radio waves. His work was purely scientific. Both Tesla, in the US, and Marconi, … Continue reading "Radio"
Machine TranslationBackground In 1933, Soviet scientist Peter Troyanskii presented “the machine for the selection and printing of words when translating from one language to another” to the Academy of Sciences of the USSR. Soviet aparchnicks during the Stalin era declared the invention “useless” but allowed Troyanskii to continue his work. He died of natural causes in … Continue reading "Machine Translation"
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"
Refrigerated Trucks1939 Frederick Jones Refrigerated trucks, invented by Frederick Jones, enable modern commerce. Jones is somewhat of an innowiki aberration in that he 1) invented something useful with enormous impact, 2) successfully commercialized it, 3) managed to keep the business and build it out, and 4) was a minority. We’d like to have a long list … Continue reading "Refrigerated Trucks"
JukeboxThe Jukebox is an automated coin-operated music player which plays individual songs. The differentiating factor of the Jukebox from a simple coin-operated record player is the ability of an automated machine to replace live music in a restaurant or bar. Background Louis Glass and William Arnold modified Edison’s record players to operate by coins. These … Continue reading "Jukebox"
Electric Arc WeldingElectric arc welding lowered the price of joining metal pieces, eventually enabling the construction of much larger structures. Russians love to build giant things, bolshoya as they say in Russian. Therefore, it makes sense that it was a Russian, Benardos Nikolai Nikolaevic, who realized in 1881 that two metal pieces can be tightly joined together … Continue reading "Electric Arc Welding"
Difference EngineBabbage’s Difference Engine, funded by Lovelace, is the first modern mechanical computer. No sooner had he announced his idea than many declared it impractical or even a hoax. Engineers eventually built a working difference engine in 2002 proving Babbage’s ideas were viable, but the engineering processes of his time were inadequate. Presently, there are working … Continue reading "Difference Engine"
UnixUnix is a computer operating system. Among other things, it allows a computer to do many things at once. Derivatives of the original Unix include Linux, MacOS, and BSD. You’re reading this right now due to a server running Unix derivative Linux. Background Dennis Ritchie and Ken Thompson worked at Bell Labs. Thompson worked on … Continue reading "Unix"
Electron MicroscopeElectron microscopes enable scientists to see extremely small particles. In the 1920s, scientists discovered that electrons in a vacuum behave much like light except they can be manipulated with electric and magnetic fields. Since electrons curve around particles, these electron microscopes are vastly more powerful than traditional light-based microscopes. Ruska invented the electron microscope at … Continue reading "Electron Microscope"
Automobile Assembly LineAssembly lines leverage standardized parts to break auto assembly into discrete components, each that can be done by a small number of people (often just one). Standardized parts evolved into standardized jobs. Ransom Olds, inspired by a musket factory that used standardized parts with workers each focused on one part, created the first auto assembly … Continue reading "Automobile Assembly Line"
Branch BankingBranch banking allows ordinary people to utilize banks and theoretically makes banks safer since larger banks are less prone to catastrophic losses than smaller banks. Amadeo Pietro “A.P.” Giannini started life as a fruit wholesaler. He built and sold a large business, decided he was too young to retire, then innovated an entirely new type … Continue reading "Branch Banking"
