Scientists suspected that an unknown metal existed in alum as early as 1787, but they did not have a way to extract it until 1825. Hans Christian Oersted, a Danish chemist, was the first to produce tiny amounts of aluminum.\n\nDuring that time, the method to extract aluminum was so costly that aluminum once was considered more precious than gold. \n\nThe plant, owned by J.G. Neher & Sons (aluminum manufacturers) started in 1886 in Schaffhausen, Switzerland, at the foot of the Rhine Falls - capturing the falls’ energy to produce aluminum. Neher's sons together with Dr. Lauber discovered the endless rolling process and the use of aluminum foil as a protective barrier. From there began the wide use of aluminum foil in the packaging of chocolate bars and tobacco products. Processes evolved over time to include the use of print, color, lacquer, laminate and the embossing of the aluminum. \n\nAlthough the technology to extract aluminum improved greatly, it still is a energy extensive process.  If you, as a chemist can figure out a way to reduce the amount of energy needed to extract aluminum even by 1%, your method can make you a millionaire overnight.  There is a thought to motivate you to study Chem.  =)

The base process, called electroplating, was invented by the chemist Luigi V. Brugnatelli in 1805. Electropolishing, which is also know was reverse electroplating, developed some time after.

Thomas Alva Edison invented the light bulb, the phonograph, automatic telegraph, motograph, paraffin paper(which was used to wrap candy), electric pen, carbon rheostat, microtasimeter, sockets, switches, insulating tape, gummed paper tape, magnetic ore separator, life-sized electric railway, motion picture camera, steel alkaline storage battery, and many other things.  He had 1,368 different patents.

Leonardo da Vinci.  Not a scientist, per se, but he did explore scientific thought and was a remarkable engineer and inventor.  Fascinating guy.

Ok, sorry if this post is confusing. It seems to me that *technically* Thomas Hancock probably invented the rubber band in 1843. Working with Hancock, Stephen Perry patented it two years later in 1845, and generally gets credited with being the inventor.\n\nAnother name that gets floated around is Dr. Jaroslav Kurash, but that rumor seems to have originated with an errant Wikipedia entry. It has also been said that William H. Spencer invented the rubber band in 1923 when he was cutting them out of discarded rubber products. It seems to me that if Perry patented the rubber band in 1845, as multiple sources say he did, it was not invented 78 years later by Spencer.\n\nAnyway, I've pasted the two main versions below, along with a bunch of sources for you to check out. You can decide for yourself.\n\n----------------------------------------------------------------------\n\n\nIn 1845, Stephen Perry, of the rubber manufacturing company Messers Perry and Co., patented the rubber band to hold papers or envelopes together.\n\nThe first rubber band was developed in 1843, when an Englishman named Thomas Hancock sliced up a rubber bottle made by some New World Indians. Although these first rubber bands were adapted as garters and waistbands, their usefulness was limited because they were unvulcanized. Hancock himself never vulcanized his invention, but he did advance the rubber industry by developing the masticator machine, a forerunner of the modern rubber milling machine used to manufacture rubber bands as well as other rubber products. In 1845, Hancock's countryman Thomas Perry patented the rubber band and opened the first rubber-band factory. With the combined contributions of Goodyear, Hancock, and Perry, manufacturing effective rubber bands became possible.\n\nhttp://www.answers.com/topic/rubber-band\n\n--------------------------------------------------\n\nHere's the William H. Spencer version:\n\nOn March 7, 1923, William H. Spencer of Alliance, Ohio, obtained rejected inner tubes from the Goodyear Co. and began cutting them into bands in his basement. Spencer, who worked for the Pennsylvania Railroad, began trying to sell his rubber bands to office-supply stores and paper and twine outlets. \n\nOne day he noticed the Akron Beacon Journal blowing across lawns and persuaded that paper to bind them with his bands. He talked the Tulsa World into doing the same, and persuaded grocers to use his rubber band instead of string to secure produce. \n\nSpencer continued working for the railroad for 14 years while building his rubber-band business at his Alliance plant. By 1944 he was able to open a second plant in Hot Springs, Ark. In 1957 he opened another, in Franklin, Ky., and one in Salinas, Calif. in 1988. The Alliance Rubber Co. now produces more than 2 million pounds of rubber bands a month in addition to other office, mailing and packaging products and sells to more than 30 countries. \n\nhttp://www.enquirer.com/editions/2003/03/07/loc_ohiodate0307.html

Are you talking about George Washington Carver? He didn't invent the peanut. He is credited with discovering the many uses of the peanut and the soybean.

James wright was an engineer at General Electric who invented silly putty in 1943.\n\nIt happened all by accident; it was World War II and the Far Eastern countries were being invaded by Japan - this made rubber difficult to come by. Any rubber that was found was used to make tires or needed war supplies. General Electric decided to hire an engineer to try to develop a cheap substitute; they hired James wright.\n\nIn 1943-quite by accident, Wright dropped some boric acid into some silicone oil, and thus, silly putty was invented...kind of Wright had no idea what to do with the stuff. see silly putty\n\nhttp://en.wikipedia.org/wiki/James_Wright_%28inventor%29\n\nhttp://en.wikipedia.org/wiki/Silly_Putty

Didn't you know? He was the creator of first self-assembly furniture. \nDoes that make him good or bad I don't know, will give this another thought while I'm trying to assemble a bookcase I carried all the way from the store.

Alexander Graham Bell is generally credited for inventing or at least developing on a grand scale, the tetrahedral kite.  He actually hoped it would be the basis for making an airplane.  He made some great, giant kites but never made a practical airplane.  Bell was much more famous for inventing the telephone.

He was a chemist who discovered guncotton and ozone.  I'm sure Wiki would have an entry on him, and maybe some actual refrences

Chemistry as we know it today was invented by Antoine Lavoisier with his law of Conservation of mass in 1783. Of course, this question can only be answered by opinion.\n\nAnother great scientist is Dmitri Mendeleev, who created the periodic table of elements. \n\nThe Nobel Prize in Chemistry will show a list of chemists and their achievements, as well. You might want to take a look at that and judge who is(was) the greatest chemist on the Earth yourself! The link below is the wikipedia entry of all the recipients of the Novel Prize in Chemisty.\nhttp://en.wikipedia.org/wiki/Nobel_Prize_in_Chemistry
