Computer Numerical Control (CNC) MachineComputer Numerical Control (CNC) machines create identical interchangeable parts. They simplify manufacturing and reduce the risk of human error producing parts. Starting in 1949, John Parsons worked with Frank Stulen at Gordon S. Brown’s Servomechanisms Laboratory at MIT to develop a system where punch cards controlled a machining tool, called Numerical Control (NC). This evolved … Continue reading "Computer Numerical Control (CNC) Machine"
Magnetic Tape RecordingPoulsen, a Danish engineer, created and patented a machine that recorded onto magnetic tape. His called the invention a Telegraphone. There was no amplification and the recording quality was poor. In 1928, Pfleumer, a German, vastly improved the magnetic tape. He named his device a Magnetophone. During WWII the Germans used it for communications and … Continue reading "Magnetic Tape Recording"
Supertall SkyscraperBuildings higher than 300 meters (984 ft.) are supertall skyscrapers. During the late 1920s there was an unofficial competition to see who could build the tallest building in New York City. Background In 1913, the Woolworth Building was the highest in New York City, at 792 feet. New York architects William Van Alen and Craig … Continue reading "Supertall Skyscraper"
BroadcastingDavid Sarnoff David Sarnoff is the father of broadcasting. Sarnoff was a Jewish immigrant who became his family’s breadwinner at age 15. He worked as a Morse Code operator, rising up the ranks to become a supervisor. Eventually, he transitioned to radio to transmit messages over long distances. Early radio technology was for point-to-point communications, … Continue reading "Broadcasting"
AutomobileIt’s difficult, and arguably pointless, to separate the innovation of the automobile and Internal Combustion Engine (ICE). The use of an ICE for a “horseless carriage” was so obvious that early engines were all used for cars. Engine propelled buggies were, by far, the most popular use case though ICE’s also powered other applications. Early … Continue reading "Automobile"
Chlorofluorocarbons “Freon”Freon is the brand name of a Chlorofluorocarbon gas. It replaced other refrigerant chemicals that were more toxic or volatile, including ammonia. Throughout the 20th century, Freon became the dominant refrigerant gas. The team that invented Freon was led by Thomas Midgley, Jr., who earlier had invented leaded gasoline. It was a joint venture between … Continue reading "Chlorofluorocarbons “Freon”"
Electronic Desktop CalculatorDesktop calculators led the idea of computers small and cheap enough to sit on an individual’s desk. Eventually, they also became the impetus for the general-purpose microchip. History The first desktop electronic calculator is the ANITA Mark VII and ANITA Mark VIIII, both launched late 1961. The Bell Punch Co. of Britain designed the ANITA. … Continue reading "Electronic Desktop Calculator"
Machine GunMaxim is a colorful character who claims to have invented everything from the asthma inhaler to automated fire sprinklers and even the lightbulb, despite Edison’s well documented account. He also experimented with helicopters, airplanes, and amusement park rides. While on vacation in Vienna he claims another American told him “If you want to make a … Continue reading "Machine Gun"

Industrial RobotThough understated at the time, few inventions have had as much impact as the industrial robot. Industrial robots were invented by George Devol. A prolific innovator, Devol patented the “Unimate” – a term he coined – in 1954 to name his robot. Robots have existed in science fiction for ages, often as machines in human … Continue reading "Industrial Robot"
Military TankTowards the late 1800s, Europeans and Americans both worked on the idea of a tire tread. They realized a treaded machine would be useful on rougher terrain. The Holt Manufacturing Company, later renamed Caterpillar, perfected and patented a working tread in 1904. While engineers experimented developing working treads for tractors their use in war was … Continue reading "Military Tank"
Traffic SignalA manually-controlled gas-powered light-switch on London Bridge was the first traffic signal. It was never popular and, in 1869, exploded and hurt the policeman controlling the switch. Subsequently, there were countless versions of semaphore lights to control traffic. None gained commercial acceptance. Morgan, who invented the gas mask, also invented and patented the modern traffic … Continue reading "Traffic Signal"
Oil DrillDrake’s oil drill is one of the stranger stories, in a collection of innovation origin stories where strange is common. The oil drill vastly lowered the cost and increased the efficiency of collecting oil. Before the drill, oil was usually collected in naturally formed pools at the ground surface. Most early oil was distilled into … Continue reading "Oil Drill"
Suez CanalThe Suez Canal connects the Arabian and Red Sea to the Mediterranean. The canal is one of the two most important human-engineered waterways in the world. Background Think your remodel took a long time? Or your software project went horribly over time and budget? Maybe a movie took too long to make? North Korea has … Continue reading "Suez Canal"
