Bubble Wrap PatentIn 1957, Alfred W. Fielding and Marc Chavannes set out to make a new type of wallpaper. Instead, they changed the world of packaging. They were attempting to develop an easy to install and clean wallpaper with a paper backing. The partners sealed two shower curtains together creating a cluster of small bubbles between the two layers. For this invention, they received U.S. Patent No. 3,142,599 on July 28, 1964 for a Method for Making Laminated Cushioning Material.

The product was unsuccessful as wallpaper. Looking for other ways to use the plastic, the duo even tried to sell it as greenhouse insulation. The use of the air cushioned material as protective packaging was discovered later. Continue reading “Shower Curtain Packing Material? Invention of Bubble Wrap”

Did you know that “Q-Tip”, “Dumpster” and “Thermos” were all trademarks at one time? Once simply brand names for “cotton swabs”, “large waste can” and “vacuum flask” respectively, all have since lost their trademark status to one common problem: genericization.

Bayer AspirinGenericized trademarks are words that used to be brand names but have become ingrained in common speech as a way to refer to all brands of a single product, not just the brand or service of the original trademark holder. A trademark often becomes genericized when one company dominates the market for a single product or is the original manufacturer of a new product. The use of a trademark as a verb will also led to the term becoming generic. Continue reading “Say This, Not That: Trademark Genericization”

Question from Harold G.:

Cherry Sundae AdOn Sunday, April 3, Google celebrated the anniversary of the first ice cream sundae with one of its famous Google Doodles. But the invention of the sundae celebrated by Google is only one of the stories about how the ice cream treat came to exist. For years, there has been an ongoing debate about how and where the sundae was invented.

Google and their doodle celebrated the anniversary of the sundae on April 3. Folks in Ithaca, New York claim that on April 3, 1892, Chester Platt who owned the Platt & Colt’s drugstore, concocted the first ice cream sundae. Reverend John M. Scott visited the store for his usual dish of vanilla ice cream after church services on Sunday. Platt decided to liven up the vanilla ice cream with cherry syrup and top it with a cherry. Scott loved the ice cream and purposed that the treat be called a Cherry Sunday after the day it was created. On April 5, 1892, Platt placed an ad in the Ithaca Daily Journal for his new 10-cent ice cream specialty. Continue reading “A Cherry on Top – Invention of the Ice Cream Sundae”

Leonardo da Vinci is known first and foremost as painter. His work includes the most famous portrait of all time, the Mona Lisa. Da Vinci was also a scientist and an inventor. More of his time was spent studying science than painting. Years after his death, it became known
that he had made important discoveries in many fields including anatomy, engineering and technology. His discoveries were found in notebooks that contain more than 13,000
pages of drawings, notes and observations.

It seems that da Vinci had planned to publish a great book of knowledge but this never happened. Instead after his death, his notebooks were scattered and can now be found in the museum collections. Although these books were very hard to read with their mirror image writing, incomplete notes, and strange spellings, the many drawings in the books prove that da Vinci had ideas for many advancements that would not have even been possible in during his
lifetime. This ideas included a helicopter, tank and solar power among others.

Below are a few of the sketches for various inventions that were found in his notebooks.

Question from Michael.:
When did Li Tian die?
-Michael

Hi Michael –

I’m assuming you mean Li Tian, the monk who is most widely credited as the inventor of fireworks. I have to admit, you almost had me stumped on this one, but again, perseverance (or should I say need-to-know stubbornness) prevailed!

Some deeper research into the invention of fireworks led me to discover Li Tian, the inventor of fireworks, apparently lived from 601 AD to 690 AD. This was during the reign of Emperor Taizong (Li Shimin), first emperor of the Tang Dynasty. As the most popular legend goes, the Emperor’s prime minister had been haunted by the ghost of an evil dragon and Li Tian’s fireworks helped scare away the evil spirit.

What’s really interesting to me is the fact that these dates contradict some widely circulated information that Li Tian unveiled his invention during the Song Dynasty in the 10th century. But, knowing the legend includes the Emperor Taizong, and having historical record of his reign during the early half of the 7th century (he ruled from 621 until his death in 649 AD ), we know this simply cannot be true.

My best guess is the confusion comes from the fact that a temple in Li Tian’s honor was built in his home region during the Song Dynasty and somewhere along the lines this was mistranslated into being the time that he also lived.

More research into Li Tian’s hometown, the temple, and a local fireworks museum helped me confirm the facts. In the process, I also confirmed that April 18, a day where offerings are made to Li Tian and fireworks are set off in his honor, is purported to be the clever monk’s birthday.

Cheers to you, Michael! This was a tough one but it got me digging deeper into both the legend and the truth about fireworks!

Great question, hope you enjoyed the answer as much as I enjoyed seeking it out!

Jonas SalkPolio was once a disease feared each summer by parents and children living in cities throughout the world. Epidemics of the disease were reported during the summer season starting in 1910. The polio epidemic of the summer of 1952 was the worst in the history of the United States. About fifty-eight thousand cases were reported with 3,145 deaths and 21,269 children left with some level of paralysis. Luckily, research was being done to develop a vaccine for this children’s illness.

A project funded by the National Foundation for Infantile Paralysis (known today as the March of Dimes), an organization founded by FDR, led to the development of a Polio vaccine. Jonas Salk, an American medical researcher and virologist, went to work at the University of Pittsburgh School of Medicine in 1947. In 1948, he began a project funded by National Foundation for Infantile Paralysis to isolate the different types of the polio virus. With this project, Salk saw the opportunity to work on developing a vaccine against polio. Continue reading “Medical Advancement: Discovery of Polio Vaccine”

Question from Sarah W.:
When was the first email sent?
-Sarah

Ray Tomlinson sent the first email in 1971. The message was sent from one Digital Equipment Corporation DEC-10 computer to another Digital Equipment Corporation DEC-10 computer which was sitting right beside it. The computers however were not connected directly to one another. The message was sent via ARPANET which was a way of networking computers used prior to the internet.

The content of the first message has been forgotten. The message was sent using the @ sign. The @ sign separated the users login name and the name of the host computer.

Today about 294 billion email message are sent each day.

8 BallThe first thermoplastic was exhibited in 1862 at the London International Exhibition. Parkesine was invented in 1855 in London by Alexander Parkes. Parkesine was an organic material made by dissolving cellulose nitrate in solvent. The material could supposedly do everything that rubber could do only it was cheaper. In 1866, Parkes formed the Parkesine Company to produce his plastic. It was not a commercial success though because it was expensive, easily cracked and highly flammable.

Celluloid, the first commercially successful industrial plastic, was invented for a surprising reason. Billiards had become a very popular game in the late part of the 19th century. At the time, billiard balls were produced from ivory and thousand of elephant were being killed to produce the game. A shortage of ivory was threatening the business of billiard ball makers, Phelan & Collander, so they offered a $10,000 reward for a substitute material. Continue reading “Billiards Anyone?

La-Z-Boy AdOn March 24, 1927, two cousins, Edward Knabusch and Edwin Shoemaker, left their steady, secure employment to start a furniture company. Knabusch was a woodworker and Shoemaker was a farmer. Shoemaker became interested in woodworking after learning about all of tools Knabusch used. They began building furniture in Knabusch’s father’s garage for their new company, the Kna-Shoe Manufacturing Company. With Shoemaker’s building talent and Knabusch marketing skills, the company began to grow.

The cousins changed the name of the company to Floral City Furniture. Borrowing money from the community, a manufacturing plant was built. It was here that the owners began designing novelty furniture. One of their first designs was for a telephone stand with a build-in seat. The product was very popular but another company soon started copying and selling the piece. Another design was a chair built for “nature’s way of relaxing.” It was an outdoor wooden chair with a reclining mechanism shaped to the contour of a person’s body. The first prototype for this chair was designed from orange crates. Continue reading “Television Viewing Just Got Better: Invention of the La-Z-Boy”
