Actually, it must have been considered quite an important thing becasue many versions of ironing boards have been patented by many people.  Many people believe that Sarah Boone, a former slave, invented the ironing board in 1892.  However, there is evidence that versions of the ironing board were patented long before that.  \n\nCheck out the websites I've listed in the sources.  Interesting!

stated the first version of the Law of conservation of mass, recognized and named oxygen (1778) as well as hydrogen, disproved the phlogiston theory, introduced the Metric system, invented the first periodic table including 33 elements, and helped to reform chemical nomenclature, not to mention where Mrs. Lavoisier's erogenous zones were.

Dimitri was not the first.  The first one to make it was a french scientist named Jibbera.  His hand writing was so terrible though, that people began to make fun of ineligble handwriting that we call it jibberish.  A few years later, Dimitri came up with it.  Too bad for the frenchman, need to work on that handwriting.

The quote is actually - "Genius is 1% Inspiration and 99% perspiration", and it was quoted by Thomas Alva Edison the most famous American Inventor who, singly or jointly, held a world record 1.093 patents. In addition, he created the world's first industrial research laboratory, 1847-1931.

He invented a "photophone", the predecessor to our fiber optics.  It was a way to transmit information, in the form of sound, over light. In addition, he invented a vacuum jacket that would eventually become the iron lung used in polio cases in the 50s.  He also pioneered into the area of desalinization, "alternative energies" and recycling.  He also invented the concept of metal detectors, using an inductive pickup coil.

I do.  I love natural fibers -- good long fiber cottons, linen (even though it is a wrinkled mess two seconds after leaving the ironing board), hemp.

I would credit Jaquard and Hollerith way way back in the 1800s for creating data cards which controlled machines.  The loom used punched holes to configure the weaving process, and Hollerith (according to the website) developed punchcards for data collection and counting purposes.  The data configured on cards was the first "software."

Pencils were first manufactered in 1564 but documented use of the pencil did not appear until Conrad Gesner used one before he died in in 1565\n\n\n\ncroatian inventor Slavoljub Eduard Penkala, inventor of thefirst practical mechanical pen and pencil

I believe it might have been Gustave Eiffel.  He's most famous for the Eiffel Tower, but he used steel frames in buildings before that.  It's interesting that he sometimes put the steel frame on the outside of the structure, rather than the inside.  A good example of this is the Nestlé chocolate factory in Noisiel, France

The English Origins: There was a noble origin to the water closet in its earliest days. Sir John Harrington, godson to Queen Elizabeth, set about making a "necessary" for his godmother and himself in 1596. A rather accomplished inventor, Harrington ended his career with this invention, for he was ridiculed by his peers for this absurd device. He never built another one, though he and his godmother both used theirs. Two hundred years passed before another tinker, Alexander Cummings,\nwould reinvent Harrington's water closet. Cummings invented the Strap,\na sliding valve between the bowl and the trap. It was the first of its kind.\nHowever, it didn't take long for others to follow Cummings lead.\nTwo years later in 1777, Samuel Prosser applied for and received a patent\nfor a plunger closet. On his heels came Joseph Bramah, only one year later.\nHis closet had a valve at the bottom of the bowl that worked on a hinge,\na predecessor to the modern ballcock. Himself a bit of a sailor, Bramah's\ncloset was used extensively on ships and boats of the era. The master toilet maker among the Englishmen would emerge in the next decade. Thomas Twyford revolutionized the water closet business in 1885 when he built the first trapless toilet in a one-piece, all china design. A preeminent potter, Twyford competed against other notable business including Wedgwood and Moulton.\n\nTwyford's design was unique in that it was of china, rather than the more common metal and wood contraptions. The internal workings of his water closet were the work of one the first pioneers of the "sanitary science." J. G. Jennings patented a washout closet in 1852. This unit had a shallow basin with a dished tray and water seal. The flush water drove the contents into the pan and then through the S-trap. It was a design the Twyford would refine and promote for the rest of the decade.

the bloke who designed it, designed the eiffel tower.  I think she was based around the lady of britannia, because britannia had a spiky crown as well. Its an guess.

I would say Tim Berners Lee, who basically invented the World Wide Web.  He also created the first web browser and currently directs the World Wide Web Consortium.

The first complex protractor was created for plotting the position of a boat on  navigational charts. Called a three-arm protractor or station pointer, it was invented in 1801, by Joseph Huddart, a U.S. naval captain. The center arm is fixed, while the outer two are rotatable, capable of being set at any angle relative to the center one.
