The first successful helicopter was the Focke-Wulf Fw 61, whose first flight was June of 1936 in Germany. The man often credited with being the inventor of the helicopter is Igor Sikorsky, whose version first flew on September 14, 1939.
A:Physician William Gilbert used the Latin word “electricus” in 1600 to describe the force substances exert when they come in contact with or are rubbed against each other. In 1752, Ben Franklin's experiments showed lightning and electricity were the same.
A:The first use of numbers and counting cannot be traced to one specific individual in ancient times. It is unknown because learning to count is a discovery and not an invention. It is believed that numbers and counting were first used almost 32,000 years ago.
A:While records in other materials date back to the late 1800s, in 1931 RCA Victor became the first company to release a vinyl record. The technology was developed further by Columbia Records and led to the release of the 12-inch, long-play album in 1948.
A:Thomas Edison was an early proponent of "hello" being used to answer telephones, but the man who invented the phone, Alexander Graham Bell, preferred the use of "ahoy" as a receptive greeting. Though Bell favored "ahoy," "hello" was the first widely used greeting for answering a telephone, meaning that technically, nothing was said before "hello" became the telephone greeting.
A:Many Roman inventions, including roads, aqueducts, sewers, cement and the Julian calendar, still see use around the world today. Roman inventions ranged from small creations to large-scale inventions like heavy infrastructure. The inventions of Romans ultimately connected the Roman Empire to Europe, and facilitated its expansion.
A:According to USHistory.org, electricity was not really "invented" by anyone, as it is a force of nature that has presumably been around since the beginning of the universe. The first person to publish a study of electricity and magnetism was William Gilbert in the year 1600.
A:Nikola Tesla designed his "Power Tower" in the early 20th century as a way to create and provide free energy for the entire planet. Although his idea never came to fruition, he began construction of the tower in 1901.
A:No single person invented medicine. The science of art and healing developed over centuries, across many cultures, and it derived from many different influences. Prehistoric medical records discovered in ancient Egypt, Babylon, China, Greece and Rome share similarities, such as the use of herbs.
A:Natural chalk is made up of prehistoric saltwater organisms high in calcium that formed rock-like sediment. There is no inventor. Chalk-based materials have been used in writing for centuries, with no known inventor.
A:Antibiotics were present in ancient times in the form of molds. British scientist Sir Alexander Fleming discovered penicillin, the first working agent that demonstrated potent antibacterial properties, in 1928. Selman Waksman coined the term antibiotic in 1941, according to the National Center of Biotechnology Information, National Institutes of Health.
A:Galileo Galilei improved upon the technology of the spyglass, creating a more powerful version that resulted in the first telescope. He also created the first pendulum clock and provided important research that concluded that the planets revolve around the Sun.
A:The first microwave oven was built in 1947. Sometime around 1946, Percy Spencer, while working for Raytheon, discovered that a magnetron developed to jam radars during World War II also melted the chocolate bar in his back pocket. Corn kernels were some of the first foods Spencer tested, and when they popped, he began attempts to heat other foods using the magnetron.
A:Several inventors created typing machines similar to a typewriter. The first person to develop, patent and mass-produce a typing machine was Rasmus Malling-Hansen of Denmark. Malling-Hansen first patented his writing ball in 1870, but continued to update and improve his typing machine for nearly a decade.
A:One possible reason for Swedish engineer Alfred Nobel's invention of dynamite was the safety of construction work and blasting rock in the mid-1800s. Nobel helped build bridges in Stockholm. Nitroglycerine was used in the detonation of rock, and it was a relatively unsafe method. According to the Nobel Prize Organization, Alfred Nobel's brother Emil was killed in a nitroglycerine explosion.
A:Alexander Graham Bell's telephone was the first of its kind to receive a patent in the United States and gain widespread commercial success. Bell was interested in sound on a conceptual level and used an observation about sound echoing from one piano to another to develop the technology that made telephone calls possible.
A:The Hubble Space Telescope was invented by Lyman Spitzer, who first proposed the concept in 1946. Spitzer, a native of Toledo, Ohio, continued analyzing photos from the Hubble Space Telescope until his passing in 1997.
A:The first airplane was invented in 1903 by Orville and Wilbur Wright. Their historical flight at Kitty Hawk, N.C., was the first time a machine with a human passenger flew under its own power. The plane rose 10 feet in the air, flew 120 feet and landed after 12 seconds.
A:While the actual date of its invention is unknown, the rocking horse is known to have been present at around 4000 B.C. in ancient Greece and Persia. Rocking horses with half-moon bases are thought to have originated from cradles. The oldest known rocking horse still in existence as of 2014 is from around 1610 and is thought to have belonged to King Charles I.
A:Paper plates were invented by Martin Keyes in the early 20th century. The inventor began to market his paper plate molding machine in 1903 after founding the Keyes Fibre Company. His first paper plate molding machine was capable of manufacturing 50,000 paper plates per day.
