Frances Gabe (actually, Frances G. Bateson) (1915-) invented and patented the self-cleaning house. Gabe, who lives in Newberg, Oregon, USA, disliked housework intensely. She designed and lives in a house in which each room has a 10-inch square, “Cleaning/ Drying/ Heating/ Cooling” device on the ceiling. To clean a room, all you have to do is push a button in a room, and the cleaning unit sends a powerful spray of soapy water around the room. It then rinses and blow-dries the room. Each room has a slightly-sloping floor, so the water would drain well. Frances stored valuable objects (and things that should not get wet) under glass. The house also has self-cleaning sinks, bathtubs and toilets. Her cupbord doubles as a dishwasher and her clothes are cleaned, dried and stored while hanging in the closet. Gabe holds 68 patents. Frances said, “Housework is a thankless, unending job, a nerve-tangling bore. Who wants it? Nobody! With my jaw set hard I was determined there had to be a better way!”
Galileo Galilei (1564-1642) was an Italian mathematician, astronomer, and physicist. Galileo found that the speed at which bodies fall does not depend on their weight and did extensive experimentation with pendulums.
In 1593 Galileo invented the thermometer.
In 1609, Galileo was the first person to use a telescope to observe the skies (after hearing about Hans Lippershey’s newly-invented telescope). Galileo discovered the rings of Saturn (1610), was the first person to see the four major moons of Jupiter (1610), observed the phases of Venus, studied sunspots, and discovered many other important phenomena.
Pantyhose was invented in 1959 by Allen Gant of North Carolina, USA, in 1959. This new undergarment became popular as miniskirts were the fashion and soon came to replace nylon stockings held up with a garter belt (short skirts were not long enough to hide the bottom of the garter belt). Gant was associated with the Glen Raven Mills textile mill (he was a descendant of the founder of the mill, John Gant), the company that first manufactured pantyhose.
Garrett Augustus Morgan (March 4, 1877 - August 27, 1963), was an African-American inventor and businessman. He was the first person to patent a traffic signal. He also developed the gas mask (and many other inventions). Morgan used his gas mask (patent No. 1,090,936, 1914) to rescue miners who were trapped underground in a noxious mine. Soon after, Morgan was asked to produce gas masks for the US Army.
Joseph Gayetty invented toilet paper in 1857. His new toilet paper was composed of flat sheets. Before Gayetty’s invention, people tore pages out of mail order catalogs - before catalogs were common, leaves were used. Unfortunately, Gayetty’s invention failed. Walter Alcock (of Great Britain) later developed toilet paper on a roll ( instead of in flat sheets). Again, the invention failed.
In 1867, Thomas, Edward and Clarence Scott (brothers from Philadelphia, Pennsylvania, USA) were successful at marketing toilet paper that consisted of a small roll of perforated paper . They sold their new toilet paper from a push cart - this was the beginning of the Scott Paper Company.
The Geiger counter (sometimes called the Geiger-Muller counter) is a device that detects ionizing radioactivity (including gamma rays and X-rays) - it counts the radioactive particle that pass through the device. The German nuclear physicist Hans Wilhelm Geiger (Sept. 30, 1882- Sept. 24, 1945) developed the device from 1908-12. At that time, Geiger was an assistant to the British physicist Ernest Rutherford (1871-1937). [Geiger’s work helped Rutherford discover that radioactive elements can transform into other elements and that atoms have a nucleus]. In 1928, the Geiger counter was improved by the German physicist E. Walther Muller.
A geologic time scale is a diagram that details the history of the Earth’s geology, noting major events like the formation of the Earth, the first life forms and mass extinctions. The first geologic time scale was proposed in 1913 by the British geologist Arthur Holmes (1890 - 1965). Holmes was also the first person to realize that the Earth was billions of years old (not millions, as had been previously believed).
The Q-tip was invented in the 1920’s Leo Gerstenzang (a Polish-born American). His wife had used a toothpick with cotton stuck on the end to clean their baby’s ears, and Leo invented Q-tips to replace her jury-rigged invention. Gerstenzang’s original Q-tips consisted of a wooden stick swathed in cotton at both ends; much later, the wood was replaced by white cardboard. Gerstenzang started the Infant Novelty Company to sell Q-tips (which he then called Baby Gays); in 1926, he changed the name of his product to Q-Tips® Baby Gays. The Q stood for “quality”. Eventually, the name changed to Q-tips. Doctors today advise that you should not use Q-tips to clean inside your ears. Q-tips, however, have many other uses, including cleaning small areas (like jewelry or the space between computer keys), applying glue, spreading paint, etc.
Eyeglasses with convex lenses for correcting farsighted vision were probably invented in Italy around the year 1268-1284, perhaps by Salvino D’Armate of Pisa or by Alessandro Spina of Florence. Early glasses were also made in China around the same time. The earliest glasses did not have arms; they perched on the bridge of the nose. Eyeglasses with concave lenses for nearsightedness (or myopia) were not invented until the 1400s.
Glasses with arms were invented in the 1600s. Bifocals (combining convex and concave lenses to correct both nearsightedness and farsightedness) were invented by Benjamin Franklin around 1775. Glasses with hinged arms were invented in 1752 by James Ayscough. Ayscough also made the first sunglasses (glasses with green- or blue-tinted lenses).
Polarizing filters (which are very effective at filtering out glare) were invented by Edwin H. Land (and patented in 1929). Katherine J. Blodgett (1898-1979) invented a micro-thin barium stearate lens coating that made glass completely nonreflective and “invisible” (patent #2,220,660, March 16, 1938).
Martin Behaim (1459-1537) was a German mapmaker, navigator, and merchant who made the earliest globe, called the “Nürnberg Terrestrial Globe”. It was made during the years 1490-1492; the painter Georg Glockendon helped in the project. Behaim had previously sailed to Portugal as a merchant (in 1480). He had advised King John II on matters concerning navigation. He accompanied the Portuguese explorer Diogo Cam (Cão) on a 1485-1486 voyage to the coast of West Africa; during this trip, the mouth of the Congo River was discovered. After returning to Nürnberg in 1490, Behaim began construction of his globe (which was very inaccurate as compared to other maps from that time, even in the areas in which Behaim had sailed). It was once thought that Behaim’s maps might have influenced Columbus and Magellan; this is now discounted. Behaim may have also developed an astrolabe. Behaim’s globe is now in the German National Museum in Nürnberg.
Robert Hutchings Goddard (October 5, 1882-August 10, 1945) was an American physicist and inventor who is known as the father of modern rocketry. In 1907, Goddard proved that a rocket’s thrust can propel it in a vacuum. In 1914, Goddard received two U.S. patents: for liquid-fueled rockets and for two- to three-stage rockets that use solid fuel. In 1919, Goddard wrote a scientific article, “A Method of Reaching Extreme Altitudes,” describing a high-altitude rocket; it was published in a Smithsonian report. Goddard’s many inventions were the basis upon which modern rocketry is based.
After many years of failed attempts and public ridicule, Goddard’s first successful rocket was launched on March 16, 1926 from a relative’s farm in Auburn, Massachusetts. It was a liquid-fueled 10-ft. rocket that he called Nell. The flight lasted 2 1/2 seconds; the rocket flew a distance of 184 feet and achieved an altitude of 41 feet.
Goddard soon moved to Roswell, New Mexico, where he developed more sophisticated multi-stage rockets, rockets with fins (vanes) to steer them (1932), a gyro control device to control the rocket (1932), and supersonic rockets (1935). In 1937, Goddard launched the first rocket with a pivotable motor on gimbals using his gyro control device. Altogether, Robert Goddard had 214 patents.
Sarah E. Goode was a businesswoman and inventor. Goode invented the folding cabinet bed, a space-saver that folded up against the wall into a cabinet. When folded up, it could be used as a desk, complete with compartments for stationery and writing supplies. Goode owned a furniture store in Chicago, Illinois, and invented the bed for people living in small apartments. Goode’s patent was the first one obtained by an African-American woman inventor (patent #322,177, approved on July 14, 1885).
James Gregory (1638-1675), a Scottish mathematician, invented the first reflecting telescope in 1663. He published a description of the reflecting telescope in “Optica Promota,” which was published in 1663. He never actually made the telescope, which was to have used a parabolic and an ellipsoidal mirror.
Many, many people were being executed during the French Revolution, and Dr. Joseph-Ignace Guillotin (1738-1821) suggested that decapitation would be a more humane method for execution. Experiments with cadavers (dead people) were done. The device that we call the guillotine was invented; it is a tall wooden framework with a hole to keep a person’s head still and a large falling blade. Although he did not invent the machine we call the guillotine, Guillotin’s name is forever attached to it. The guillotine was first was used on April 25, 1792 at the Place de Grève (the victim was a highway man). The most famous victims of the guillotine include the deposed French King Louis XVI and his extravagant wife Queen Marie Antoinette, who were beheaded on January 21, 1793. The guillotine was used in France until 1981, when capital punishment was abolished.
Gunpowder was invented in China, probably during the 1000’s. Gunpowder is composed of about 75 percent saltpeter (potassium nitrate), 15 percent powdered charcoal, and 10 percent sulphur. The Chinese used gunpower to make fireworks and signals, and later to make weapons of war.
Johannes Gutenberg (the 1300’s-1468) was a German craftsman, inventor, and printer who invented the first printing press with movable type in 1450. This invention revolutionized printing, making it simpler and more affordable. Gutenberg produced dies (molds) for easily producing individual pieces of metal type that could be made, assembled, and later reused. Gutenberg’s new press could print a page every three minutes. This made printed material available to the masses for the first time in history. Religious materials were the majority of the early printed materials. The use of printing presses began the standardization of spelling.
A gyroscope is essentially a spinning wheel set in a movable frame. When the wheel spins, it retains its spatial orientation, and it resists external forces applied to it. Gyroscopes are used in navigation instruments (for ships, planes, and rockets). Jean Bernard Léon Foucault (1819-1868), a French physicist, invented the gyroscope in 1852.
