Who Invented Aluminum Foil?

Who Invented Aluminum Foil?...

A study of the history of aluminum foil indicates that on April 2, 1889, Charles Martin Hall got a patent for producing the metal. The first rolling plant came out in 1910, called Dr. Lauber, Neher, Cie and Emmishofen. This was in Kreuzlingen, Switzerland. Early History and Origin Before aluminum foil came out, tin foil was used for packing foods and other products. The metal was stiff and could leave an adverse effect on the food. It was in 1825 that aluminum was discovered, courtesy of Hans Christian Oersted. The Danish chemist was the first to show actual samples of the foil. In 1845, the German scientist Friedrich Wohler was able to produce bigger samples. Through his work the basic characteristics of the metal could be discerned. This was a crucial point in the history of aluminum foil. It was in 1854 that the French chemist Henry Deville developed the means for mass producing it. Despite his efforts, foil was still too expensive to be of any practical use. It was not until Hall’s invention that the material became affordable. The patent number of the US inventor was #400,666. In 1888, Hall set up the Pittsburgh Reduction Company. It would become known as the Aluminum Company of America. From $1,200 a kilo in 1852, the cost of aluminum foil had gone down to 18 cents per pound in 1914. Another important inventor was Karl Joseph Bayer. In 1888, the Austrian chemist invented a process so aluminum oxide could be extracted from bauxite. This was another vital chapter in the history of aluminum foil. Today his methodology is still being used. The Lauber Aluminum Rolling Plant The Lauber plant in Switzerland was maintained by J.G. Neher and his sons. Their...
Who Invented DNA Fingerprinting?

Who Invented DNA Fingerprinting?...

DNA fingerprinting (also known as DNA typing) is a special technique used to identify individuals based on their DNA profiles. One of the important uses of this technique is to provide reliable and credible evidence in courts. Other uses of the technique are for identifying one’s paternity and maternity as well as for personal identification. In several countries, the national government has DNA databases, which contain the DNA structures of citizens. To know more about this technique, let us take a look at the history of DNA fingerprinting. History of DNA Profiling Who invented DNA fingerprinting? DNA profiling was invented by scientist Sir Alec Jeffreys in his laboratory at the University of Leicester in Great Britain in 1985. The reason behind the invention of the technique is to identify which parts of the DNA sequences are different from an individual to another. However, at this time, the technologies that they can use to determine the sequences were limited. In this regard, Jeffreys only found small differences in the sequence when in fact; there are numerous variable sequences in the DNA. Jeffreys continued searching for techniques that can be used to identify all the varying sequences named as minisatellites. In order to succeed, he created a special probe that would be used to check if the minisatellites would react with a myoglobin gene. To do the experiment, he got DNA samples from his parents. On September 10, 1984, Jeffreys saw an inheritance pattern between the samples. He found out that DNA fingerprinting is a highly efficient technique that can be used to identify one’s paternity as well as maternity. He reported his findings in lectures and reports. He also published research at the Nature magazine about the technique. Two weeks...
Who Invented Pizza?

Who Invented Pizza?

No One Knows Who Created the Very First Pizza. Bread was said to have originated in prehistoric times, and was considered the first form of prepared food. But much can be inferred on the true historical beginnings of who invented pizza. There seems to be a question on whether the ancient Greeks or the Egyptians invented this delicious food. This is because during earlier times, some say that these people were seen to have eaten a pizza-like food. Still, the question on who invented pizza for the first time ever is still shrouded in mystery up to now. The City of Naples Became the Starting Point of Further Developments. Nevertheless, there are certain accounts that Naples is considered as the birthplace of a more modern-day pizza. Their earlier version was called focaccia and was a simple concoction of flat circles of dough with minimal ingredients. This flattened dough was baked to perfection and sprinkled with various herbs and spices. Their simple recipe, famous with peasants during that time, has been the focal point that brought about the other developments of pizza recipes. The First Pizza Parlors Worldwide Brought Pizza to More People. In 1738, still in the city of Naples, the first pizza parlor or pizzeria was born. This was named as Antica Pizzeria Port’Alba. How they prepare their pizza dishes is really interesting. They use an oven which uses lava from Mount Vesuvius to cook their pizzas. In 1889, another tavern in Naples, owned by by Don Raffaele Esposito, added more ingredients to the first recipe of pizza when they were visited by the Queen Margherita Teresa Giovanni and King Umberto I. To be specific, they made the dish more special by adding basil and mozzarella cheese. This...

Who Invented the Snickers Candy Bar?...

Snickers is one of the most popular brands of chocolate candy bar made in the United States. The primary ingredients of the merchandise are milk chocolate, caramel, corn syrup, lactose, egg as well as peanut butter nougat. Based on studies, it is the best selling candy of all time with the yearly worldwide sales of $2 billion. In Ireland and Great Britain, the product bears the brand name Marathon. To know more about the history of the merchandise, it is best to begin with identifying the person behind the invention of the food. History of the Chocolate Who invented the Snickers candy bar? Franklin Clarence Mars, owner of Mars Inc., invented the chocolate bar in the early 1900s. The food was introduced by the company to the public in 1930. The name of the merchandise was inspired by the name of the favorite horse of the inventor. To enhance the taste of the candy bar, Mars added special ingredients in the merchandise such as artificial flavoring, soy lecithin, skimmed milk, cocoa butter, sugar and peanuts. The popularity of the food improved when it was launched in different countries including Australia several years after the death of the inventor. Additional Information and Other Important Details To attract consumers Mars Inc. produced variations of the food including Snickers Munch in 1970, Snickers Almond Bar in 2002, Cookies and Snickers in 2002, Snickers Marathon in 2004, Snickers Duo in 2006 and Snickers Xtreme in 2006. In the United States and Australia, the candy bar is widely used in preparing desserts presented in special food trades. One of the most famous ways of cooking the chocolate is by deep-frying. In Great Britain, it became more popular when chef Antony Thompson made the Snickers...
Who Invented Medicine?

Who Invented Medicine?

The history of medicine began when primitive peoples learned to use plants and herbs to cure their illnesses. There are 25,000 year old drawings in the Lascaux caves in France showing plants being used for healing. These drawings are the earliest evidence of plant medicinal use. Medicine in Ancient Egypt The oldest known Egyptian remedies go back to 3000 BC. As far back as 2750 BC the Egyptians had performed rudimentary forms of surgery. The Edwin Smith papyrus states the Egyptians dealt with illnesses by examination and doing prognosis. It should be noted though that the Edwin Smith papyrus is just one kind. Other papyri showed the Egyptians relying on magic to ward off diseases. Greek and Roman Medicine The history of medicine in Greece was quite advanced. Hippocrates has been termed the father of modern medicine. Hippocrates and his corpus were the ones who first recognized the importance of finger clubbing in detecting lung ailments. Hippocrates also classified illnesses as either chronic, endemic etc. He is also the first doctor to perform chest surgery. But he is probably best known for the Hippocratic Oath, which is still taken by doctors today. The Romans were noted for their surgical instruments. They were the ones who made use of scalpels, surgical needles and specula. They were also instrumental in developing cataract operations. Medicine in the Medieval Age A study of the history of medicine shows that it suffered a decline during ths period. The fall of Rome was followed by economic collapse. Except for a few monasteries, medical knowledge were limited to the few. People relied on superstition and folklore to get rid of ailments. It was only during the Renaissance that interest in medicine was reignited. It began with...
