You probably know about George Washington
Carver already, but did you know that African Americans
have invented so much more? Without these inventions,
we wouldn't have tall buildings or shoes or be able
to live in hot climates comfortably. Elevators, shoe
fasting machines and air conditioning were all invented
by African Americans.
Benjamin
Banneker (1731 – 1806) Benjamin
Banneker was a scientist, astronomer, inventor and writer.
Banneker was one of the first African Americans to be
recognized for his accomplishments in science.
In 1753, he built the first watch made in America,
a wooden pocket watch. Twenty years later, Banneker
made astronomical calculations that predicted a 1789
solar eclipse. His estimate was different than ones
made by more well-known mathematicians and astronomers
of the time. Banneker was right!
Banneker is best known for the six annual Farmer's
Almanacs he published between 1792 and 1797. These almanacs
included information on machines and medical treatment,
and listed tides, astronomical information, and eclipses,
all calculated by Banneker himself.
Banneker's mechanical and mathematical abilities impressed
many, including Thomas Jefferson who met Banneker
while he was working with the surveying team that laid
out Washington D.C.

Elijah McCoy (1843–1929)
Elijah McCoy was the son of former slaves who escaped
via the Underground Railroad. When he was 15 Elijah
McCoy traveled to Scotland and studied mechanical engineering.
When McCoy returned to the United States he couldn't
get an engineering job because he was of African descent.
He instead took a job as a railroad fireman (the person
who put wood into the furnace).
At that time, locomotives needed to be shut down to
be lubricated so they wouldn't overheat. McCoy developed
a “lubricating cup” for steam engines. This
invention kept the locomotives constantly lubricated.
It preventing frequent stops and overheating, and made
the railroad more profitable. He patented the lubricating
cup in 1872. It worked so well that machinists and engineers
who wanted genuine McCoy lubricators began to use the
expression "the real McCoy" to request his
product.
McCoy patented more than 50 other inventions, included
a folding ironing board and an automatic sprinkler.

Granville T. Woods
(1856–1910) Granville T. Woods learned his skills
on the job. Although he had to leave school when he
was only ten, Granville T. Woods knew that learning
and education were the tools that would allow him to
express his creativity with machinery. Woods taught
himself by working in railroad machine shops and steel
mills, and by reading about electricity. He had friends
check out library books for him, since African-Americans
were not allowed to use many libraries at the time.
Woods used what he learned to to invent "telegraphony".
This invention was purchased by Alexander Graham Bell's
company. Telegraphony combined features of both the
telephone and telegraph and allowed operators to send
and receive messages more quickly than ever before.
Woods also invented the multiplex telegraph. This device
helped dispatchers locate trains and allowed moving
trains to communicate by telegraph.

Garrett Morgan
(1877–1963) Garrett A. Morgan was born in Paris,
Kentucky on March 4, 1877. Like many African-Americans
youth of his day, Morgan had to leave school at a young
age to work. However the teenaged Morgan hired his own
tutor, and continued studying while working as a sewing
machine repairman.
In 1907, Morgan opened his own sewing machine repair
and tailoring shop which employed 32 people. This was
the first of many successful businesses. He also established
a newspaper, The Cleveland Call, in 1920. Morgan became
a wealthy and respected business man. He is reported
to have been the first African American to own an automobile.
It was Morgan's experience while driving along the streets
of Cleveland that led to his invention of a new type
of traffic signal.
In 1912, Morgan invented the safety hood and smoke
protector. His invention became known nationally when
he used it to save 32 men stuck in a cave collapse near
Lake Erie. Fire Departments around the country wanted
the gas masks. The invention won gold medals from the
International Association of Fire Chiefs and the International
Exposition of Sanitation and Safety. When the U.S. entered
World War I the Morgan gas mask was used to equip American
troops.

Sarah Boone took
an already great idea and made it better! Sarah Boone,
patented an improvement to the ironing board (U.S. Patent
#473,653) on April 26, 1892. Sarah Boone's ironing board
was designed to be effective in ironing the sleeves
and bodies of ladies' garments.

Sarah Goode
was born
into slavery in 1850, Sarah Goode was the first African
American Woman to receive a U.S. patent. Her invention,
called a "cabinet bed" was what we know of
today as a folding bed or "hide away" bed.
Goode owned a furniture store, and knew that people
living in small city apartments often had a hard time
finding space for beds. Her "cabinet bed"
folded up into a desk for daytime use.
Madame C. J. Walker
(1867 – 1919) Sarah Breedlove McWilliams Walker,
better known as Madame CJ Walker, was born in rural
Louisiana. Orphaned at 7 Walker worked the cotton fields
and later as a laundry woman. Walker suffered a scalp
ailment that caused her to lose some of her hair. Embarrassed
by her appearance, she began experimenting with various
home remedies, eventually creating and selling Madam
Walker's Wonderful Hair Grower, a scalp conditioning
and healing formula.
The business that Madame Walker created with her famous
beauty products employed as many as 3,000 people. Her
creativity and ambition led her to be the first known
African-American woman to become a self-made millionaire.

Jan Matzelinger
(1852 – 1889) When Jan Matzeliger immigrated to
the United States at age 18 he spoke no English. He
found work in a shoe factory in Philadelphia.
Hundreds of inventors and thousands of dollars had
been spent in an effort to make a complete shoe by machinery.
Machines where able to perform all but the final step,
that of shaping the upper leather over the last and
attaching this leather to the bottom of the shoe. Workers
called "Hand-lasters" performed this this
final step by hand. Hand lasters where very highly paid,
however no matter how fast the other portions of the
show were completed, the best hand laster could only
complete 50 pairs per day.
Matzliger heard it said many times that it was impossible
to last shoes by machines; the job simply could not
be done. In secret he started experimenting, first with
a crude wooden machine, then with a model made out of
scrap iron. For ten years he worked, steadily and patiently,
with no encouragement.
Finally in 1882, Matzelinger felt he had perfected
his machine to solve the impossible problem.
