A man of many talents, Benjamin Banneker was one of the first distinguished African American scientists and mathematicians. He was also an inventor and a writer. Banneker was born on November 9, 1731, in Ellicott’s Mills, Maryland. His father had been enslaved, but Benjamin was free.

Why did Benjamin Banneker stop publishing his almanac?​

Why did Benjamin Banneker stop publishing his almanac?

How did George Bannekar contribute to the field of astronomy?
George Ellicott lent Bannekar many books on astronomy and a telescope and tools that were used in astronomy. Bannekar learnt astronomy all by himself. In 1789, he accurately predicted a solar eclipse and became the first African-American to be appointed to the President’s Capital Commission.
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.

What is a Banneker clock?​

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.

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.

How did Banneker get started in mathematics?​

How did Banneker get started in mathematics?
One customer was a neighbor named George Ellicott, a surveyor. He was so impressed with his Banneker’s work and intelligence, he lent him books on mathematics and astronomy. With this help, Banneker taught himself astronomy and advanced mathematics. Starting about 1773, he turned his attention to both subjects.

How did Benjamin Banneker make the first wooden clock?​

Banneker then carved large-scale wooden replicas of each piece, calculating the gear assemblies himself. He used the parts to make the first wooden clock in the United States. It continued to work, striking each hour, for more than 40 years.

Did Banneker have any experience with astronomy?​

Not only was Banneker acutely interested in astronomy but he actually succeeded in predicting the solar eclipse of 14th April, 1789. Again, Banneker was not a trained astronomer or a mathematician. He used the books that amateur astronomer George Elliot lent him to develop his understanding.

Was Banneker’s story an anomaly?​

Was Banneker’s story an anomaly?
Despite his many accomplishments, however, Banneker was forced to navigate the same racial prejudices that African Americans often faced in both slave and free states. In many ways, his story is an historical anomaly.

Benjamin Banneker, 18. yy.ın en önemli Afrika kökenli bilim insanlarından biri olarak bilinir. Ayrıca mucit ve yazar olan Banneker, 9 Kasım 1731'de Maryland'de doğmuştur ve kölelikten kurtulmuş bir ailenin çocuğuydu. Babası kölelik yaşamış olsa da Benjamin serbestti.

Banneker, kendi Almanaklarını Benjamin Franklin'in "Poor Richard's Almanac"ı ile kıyaslanacak kadar başarılı bir şekilde yazıyordu. Ancak, 1802 yılında düşük satışlar nedeniyle Almanağı yayınlamayı bıraktı.

1791 yılında Andrew Ellicot, başkent Washington DC'nin arazi ölçümlerinde ona yardım etmesi için Banneker'ı işe aldı. Banneker, gözlem çadırında çalışarak yıldızların hareketlerini kaydetmek için zenith sektörü kullandı.

Banneker'ın astronomi alanına katkıları arasında, George Ellicott'un ona ödünç verdiği astronomi kitapları, teleskop ve astronomi için kullanılan araçlarla kendi kendine astronomi öğrenmesi yer alır. 1789 yılında güneş tutulmasını doğru bir şekilde tahmin ederek, Başkanın Başkent Komisyonuna atanan ilk Afrika kökenli Amerikalı oldu.

1761 yılında Banneker, hiç saat görmemiş olmasına rağmen (ceplerindeki saat hariç), ahşaptan vurmalı bir saat yapmayı başarmıştır. Ahşaptan dişli tekerlekler ve dişlileri titizlikle oymuştur.

Banneker'ın eğitimi sadece yakındaki bir Quaker köy okuluna devam etmekle sınırlıydı. Daha sonra kendisine edebiyat, tarih ve matematik öğreten ve okumaktan zevk alan Banneker, yetişkin bir birey olduğunda büyük ebeveynlerinden kalan çiftliği miras almıştı.

Banneker, matematikle ilgilenmeye 1773 yılı civarında başladı. Komşusu George Ellicott, bir haritacıydı ve Banneker'ın işine ve zekasına çok etkilendiği için ona matematik ve astronomi kitapları ödünç verdi. Bu yardımla Banneker, kendisini astronomi ve ileri matematik konularında geliştirdi.

Son olarak, Banneker'ın bir hikayesi olağanüstü olmasına rağmen, birçok başarısına rağmen, köle ve özgür eyaletlerde sık sık karşılaşılan Afrika kökenli Amerikalılar tarafından maruz kalınan ırksal önyargılarla baş etmek zorunda kaldı. Banneker'ın hikayesi bir anlamda tarihsel bir istisnadır.
