Foods to improve sex drive in males

In at least one branch of industry, America owes its supremacy to an African American, Jan Ernest Matzeliger. InB4 MTV falsely DMCA this video because it proves they are wrong about pretty much everything. Despite the hardships suffered through slavery, many African Americans have managed to become great inventors, scientists, and thinkers.
The magnitude of an inventors work can often be defined by the esteem in which he is held by fellow inventors.
Garrett Morgan was an inventor and businessman from Cleveland who invented a device called the Morgan safety hood and smoke protector in 1914.
A pioneer in the art of shoemaking, he enriched America and other nations by billions of dollars, made a dozen or more millionaires, created work for hundreds of thousands, and contributed enormously to what is regarded as one of the distinct features of civilization, namely, the wearing of shoes. Frederick Jones patented more than sixty inventions, however, he is best known for inventing an automatic refrigeration system for long-haul trucks in 1935 (a roof-mounted cooling device). He was a shoemaker by trade, the son of an African homemaker and a Dutch engineer, in whose machine shop Jan Matzeliger began working at the age of ten. Patricia Bath, an ophthalmologist from New York, but living in Los Angeles when she received her patent, became the first African American woman doctor to receive a patent for a medical invention. On July 25, 1916, Garrett Morgan made national news for using his gas mask to rescue 32 men trapped during an explosion in an underground tunnel 250 feet beneath Lake Erie.
One of his early inventions was an improved electrical resistor for computers, radios, televisions and an assortment of other electronic devices. With no other capital but his meager wages, he was forced to make use of such material as he could get hold of. Jones was the first person to invent a practical, mechanical refrigeration system for trucks and railroad cars, which eliminated the risk of food spoilage during long-distance shipping trips. An x-ray spectrometer assists scientists in identifying a material by producing an x-ray spectrum of it, allowing it to be examined visually.
Other notable inventions include a variable resistor used in guided missiles and small component thick-film resistors for computers.

Madam Walker was an entrepreneur who built her empire developing hair products for black women.
Jan Matzeliger helped revolutionize the shoe industry by developing a shoe lasting machine that would attach the sole to the shoe in one minute.
This is especially advantageous when the material is not able to be broken down physically.
4,744,360), a method for removing cataract lenses, transformed eye surgery, using a laser device making the procedure more accurate (Cataract Laserphaco Probe). After the rescue, Morgan’s company received requests from fire departments around the country who wished to purchase the new masks. For six months he toiled strenuously until he had constructed a model which though crude, gave him confidence that he was on the road to success.
She claims to have built her company on an actual dream where a large black man appeared to her and gave her a formula for curing baldness. The shoe lasting machine adjusts the shoe leather upper snugly over the mold, arranges the leather under the sole and pins it in place with nails while the sole is stitched to the leather upper. This device heated sugar cane juice in a partial vacuum, reducing its boiling point, allowing much greater fuel efficiency.
In 1887, Woods developed his most important invention to date – a device he called Synchronous Multiplex Railway Telegraph.
The probe, patented in 1988, is designed to use the power of a laser to quickly and painlessly vaporize cataracts from patients’ eyes, replacing the more common method of using a grinding, drill-like device to remove the afflictions.
When confronted with the idea that she was trying to conform black women’s hair to that of whites, she stressed that her products were simply an attempt to help black women take proper care of their hair and promote its growth. This innovation, adopted in sugar refining, escalated production, reduced the price, and was responsible for transforming sugar into a household item.
With another invention, Bath was able to restore sight to people who had been blind for over 30 years. He was offered $1,500 for his invention of pleating the leather around the toe, which sum he refused.

Similar technology was subsequently developed for the production of soap, gelatin, and glue.
Latimer devised a way of encasing the filament within an cardboard envelope which prevented the carbon from breaking and thereby provided a much longer life to the bulb and hence made the bulbs less expensive and more efficient. By allowing dispatchers to know the location of each train, it provided for greater safety and a decrease in railway accidents. Greatly encouraged by the widespread interest his model created, he started to build a better one.
Some have called Rillieux’s evaporator the greatest invention in the history of American chemical engineering.
Over the course of his life time Granville Woods would obtain more than 50 patents for inventions including an automatic brake and an egg incubator and for improvements to other inventions such as safety circuits, telegraph, telephone, and phonograph.
After witnessing a collision between an automobile and a horse-drawn carriage, Garrett Morgan took his turn at inventing a traffic signal. With his new model it was easy for him to convince practical men that his invention would work successfully.
Other inventors had experimented with, marketed, and even patented traffic signals, however, Garrett Morgan was one of the first to apply for and acquire a U.S. A company was formed, consisting of himself, those who had advanced him money from time to time, and some others with large capital. With this new invention, the United Shoe Machinery Company rapidly drove competitors out of the shoe business until, a few years later, it controlled 98 percent of the shoe machine business.
