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"
Antibiotics“I did not invent penicillin. Nature did that. I only discovered it by accident.” Sir Dr. Alexander Fleming Few medical discoveries impacted life expectancy and quality of life more than antibiotics. Before their discovery, simple wounds were often fatal. For example, during the US Civil War, most soldiers eventually died from infection, not from their … Continue reading "Antibiotics"
Movie SoundTalkie movies increased fun but also increased the utility of movies by enabling the transmission of news with pictures. Newsreels, that started out as shorts played before movies, evolved into the most effective communication method in history. Tigerstedt created the first documented movie sound technology, in 1914. However, his technology was not commercialized. Lee de … Continue reading "Movie Sound"
PlasticAs described in the post about rubber, Charles Goodyear created the vulcanization plastic making mass-market rubber possible. Goodyear’s durable rubber enabled an entire field of new products from tires to raincoats. However, rubber is both thick and spongy, giving it limited utility. Nobody is going to create a rubber telephone and a rubber water bottle … Continue reading "Plastic"

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 AdvertisingBefore Albert Lasker advertisements tended to be crude, raising awareness or reinforcing a brand name. Many ads were not much more than offers to purchase something, with no overarching idea. Lasker used the emerging science of psychology and budding technology of radio to radically change advertising. Background Born in Germany, Lasker moved to the US … Continue reading "Modern Advertising"
PatentsPatents protect the invention of things but not works of art or trademarks, which have their own body of law. They give a limited monopoly for an inventor to produce or license their invention for a set amount of time. Throughout history, patent law has inspired and rewarded innovation but also stifled innovation when abused. … Continue reading "Patents"
Matches1827 Friction matches are ordinary matches. Strike them against a flint or, for some types, any hard service and they start a fire. Friction Matches were invented by Englishman John Walker in 1827. While it seems hard to believe it took so long before the innovation of matches by Walker people would have to find … Continue reading "Matches"
Public-Key Cryptography (Public key encryption)Public Key Cryptography (PKC) dramatically lowers the risk of information intercept and also lowers the risk of impersonation. PKC vastly increases security. For example, Google allows people to send queries to them encrypted. But they cannot decrypt the queries sent by others with what they give you, only Google can. Besides encrypting and decrypting, public … Continue reading "Public-Key Cryptography (Public key encryption)"
ImmunotherapyIt’s common for meaningful inventions to take years or even decades to reach their commercial potential. At about 110 years from discovery to practical use, immunotherapy is the second longest invention we’ve found after the Suez Canal. Immunotherapy is the process of training the body’s natural immune system to attack and destroy cancer cells. The … Continue reading "Immunotherapy"
FiberglassFiberglass has multiple uses. It acts as an insulator, building material, and even boat hulls. First, in 1870, John Player developed a process to mass-produce glass strands with seam jets used for insulation. By and large, this is arguably the first fiberglass. Eventually, in 1880, Herman Hammesfahr patented weaving glass fibers to silk, making it … Continue reading "Fiberglass"
VideoconferencingVideoconferencing is well over 50 years old. Today, it is fast and virtually free over the Internet. However, aside from extremely formal or informal events, videoconferencing has largely failed to catch on. Background AT&T introduced videoconference at the 1964 World’s Fair. People in New York waited in line to walk into a booth and spend … Continue reading "Videoconferencing"
Fast FoodMcDonald’s primary innovation is that food should be ready instantly. No sooner does a customer order than food appears. Individual restaurant orders, individually prepared was the norm for non-buffet restaurants before McDonald’s. In 1937, the McDonald brothers created their iconic restaurant and built several stores. Eventually, Ray Kroc was a 52-year-old milkshake machine salesman who … Continue reading "Fast Food"
Coke Fueled Blast Furnace / Pig Iron1709 Abraham Darby used Coke instead of coal to fire blast furnaces, making the production of iron from pig iron (a weak iron), much more economical. Coke burns significantly hotter than coal which, combined with his new design to concentrate the heat, his factory was significantly more efficient than prior methods. He created the Bristol … Continue reading "Coke Fueled Blast Furnace / Pig Iron"
Cotton GinWhitney’s innovation vastly lowered the price of cotton. Before Whitney’s cotton gin, producing cotton was economically inefficient because of the enormous cost to separate cotton from seeds. After the innovation, cotton became a profitable crop. Background Coming of age during the Revolutionary War, Whitney made a nail company, at the age of 15. Later, he … Continue reading "Cotton Gin"
