Dixon introduced graphite pencils in 1829. when the American Civil War created a demand for a dry, clean, portable writing instrument and led to the
mass production of pencils.
N. J. Conte, in 1795, successfully produced pencils, after the later famed Faber family of Nuremberg, Germany, failed to do so, by using a pulverized graphite base to create a substandard, crude prototype of a pencil

Q: #9, Who invented the steam machine?
A: Matthias W. Baldwin
American manufacturer of steam locomotive. He opened his machine shop in 1825. The business grew to become Baldwin Locomotive Works, one of the most prolific and successful locomotive manufacturing firms in America.
The steam engine was not so much invented as developed. To give credit to any one person would be to steal credit away from its many rightful owners. The steam engine was developed over a period of about a hundred years by three British inventors.

Q: #13, Who invented the steam locomotive?
A: Peter Cooper
Tom Thumb was the first American-built steam locomotive used on a
common-carrier railroad. Designed and built by Peter Cooper in 1830,
After ten months' labor,
George Stephenson's locomotive "Blucher" was completed and tested on the Cillingwood Railway on
July 25, 1814. The track was an uphill trek of four hundred and fifty feet. George Stephenson's engine hauled eight loaded coal wagons weighing thirty tons, at about four miles an hour. This was the first steam engined powered locomotive to run on a railroad and it was the most successful working steam engine that had ever been constructed up to this period, this encouraged the inventor make further experiments.

Q: #18, Who invented the gas mask?
A: Garrett Morgan
Morgan observed that smoke and fumes tend to rise during a fire. The device consisted of a heat-resistant hood connected to a long inlet tube that ran down to the ground to the layer of clean air beneath the smoke or gas. The end of the tube was plugged with absorbent material that was moistened before use to filter and cool air that was inhaled. A separate tube containing a valve provided an outlet for exhaled air.

was this the first, and is it realy a gas mask, it surely was a good invension for it's time.
