African American scientist and inventor
From 1792 through 1797 Benjamin Banneker, an African American mathematician and amateur astronomer, calculated ephemerides (tables of the locations of stars and planets) for almanacs that were widely distributed and influential. Because of these works, Banneker became one of the most famous African Americans in early U.S. history.
On November 9, 1731, Benjamin Banneker was born in Baltimore County, Maryland. He was the son of an African slave named Robert, who had bought his own freedom, and of Mary Banneky, who was the daughter of an Englishwoman and a free African slave. Benjamin grew up on his father's farm with three sisters. After learning to read from his mother and grandmother, Benjamin read the bible to his family in the evening. He attended a nearby Quaker country school for several seasons, but this was the extent of his formal education. He later taught himself literature, history, and mathematics, and he enjoyed reading.
As he grew into an adult, Banneker inherited the farm left to him by his grandparents. He expanded the already successful farm, where he grew tobacco. In 1761, at the age of thirty, Banneker constructed a striking wooden clock without having ever seen a clock before (although he had examined a pocket watch). He painstakingly carved the toothed wheels and gears of the clock out of seasoned wood. The clock operated successfully until the time of his death.
At the age of fifty-eight Banneker became interested in astronomy (the study of the universe) through the influence of a neighbor, George Ellicott, who lent him several books on the subject as well as a telescope and drafting instruments (tools used in astronomy). Without further guidance or assistance, Banneker taught himself the science of astronomy. He made projections for solar (of the Sun) and lunar (of the Moon) eclipses and computed ephemerides for an almanac. In 1791 Banneker was unable to sell his observations, but these rejections did not stop his studies.
In February 1791 Major Andrew Ellicott (1754–1820), an American surveyor (one who maps out new lands for development), was appointed to survey the 10-mile square of the Federal Territory for a new national capital. Banneker worked in the field for several months as Ellicott's scientific assistant. After the base lines and boundaries had been established and Banneker had returned home, he prepared an ephemeris for the following year, which was published in Baltimore in Benjamin Banneker's Pennsylvania, Delaware, Maryland and Virginia Almanack and Ephemeris, for the Year of Our Lord, 1792; Being Bissextile, or Leap-Year, and the Sixteenth Year of American Independence. Banneker's calculations would give the positions of the planets and stars for each day of the year, and his almanacs were published every year from 1792 until 1797.
Banneker forwarded a copy of his calculations to Thomas Jefferson (1743–1826), then secretary of state, with a letter criticizing Jefferson for his proslavery views and urging the abolishment (ending) of slavery of African American people. He compared such slavery to the enslavement of the American colonies by the British crown. Jefferson
The last known issue of Banneker's almanacs appeared for the year 1797, because of lessening interest in the antislavery movement. Nevertheless, he prepared ephemerides for each year until 1804. He also published a treatise (a formal writing) on bees and computed the cycle of the seventeen-year locust.
Banneker never married. He died on October 9, 1806, and was buried in the family burial ground near his house. Among the memorabilia preserved from his life were his commonplace book and the manuscript journal in which he had entered astronomical calculations and personal notations. Writers who described his achievements as that of the first African American scientist have kept Banneker's memory alive. Recent studies have proven Banneker's status as an extremely capable mathematician and amateur astronomer.

i got an A+ I gaduated
of aviation,
there is no way a bee
should be able to fly.
Its wings are too small to get
its fat little body off the ground.
The bee, of course, flies anyway
because bees don't care
what humans think is impossible.
Yellow, black. Yellow, black.
Yellow, black. Yellow, black.
Ooh, black and yellow!
Let's shake it up a little.
Barry! Breakfast is ready!
Ooming!
Hang on a second.
Hello?
- Barry?
- Adam?
- Oan you believe this is happening?

- You got lint on your fuzz.
- Ow! That's me!
- Wave to us! We'll be in row 118,000.
- Bye!
Barry, I told you,
stop flying in the house!
- Hey, Adam.
- Hey, Barry.
- Is that fuzz gel?
- A little. Special day, graduation.
Never thought I'd make it.
Three days grade school,
three days high school.
Those were awkward.
Three days college. I'm glad I took
a day and hitchhiked around the hive.
You did come back different.
- Hi, Barry.
- Artie, growing a mustache? Looks good.
- Hear about Frankie?
- Yeah.
- You going to the funeral?
- No, I'm not going.
Everybody knows,
sting someone, you die.
Don't waste it on a squirrel.
Such a hothead.
I guess he could have
just gotten out of the way.
I love this incorporating
an amusement park into our day.
That's why we don't need vacations.
Boy, quite a bit of pomp...
under the circumstances.
- Well, Adam, today we are men.
- We are!
- Bee-men.
- Amen!
Hallelujah!
Students, faculty, distinguished bees,
please welcome Dean Buzzwell.
Welcome, New Hive Oity
graduating class of...
...9:15.
That concludes our ceremonies.
And begins your career
at Honex Industries!
Will we pick ourjob today?
I heard it's just orientation.
Heads up! Here we go.
Keep your hands and antennas
inside the tram at all times.
- Wonder what it'll be like?
- A little scary.
Welcome to Honex,
