Benjamin Banneker was a noted African American inventor, mathematician, astronomer, and writer. The son of Robert and Mary Banneker, Benjamin was born in 1731 in Ellicott's Mills, Maryland. He was the oldest of four children. As a youngster, he helped his father on the family's homestead. From a very early age, Benjamin showed evidence of being especially bright, so his grandmother favored him and spent time nurturing his interests. Unlike many young men at his school, Benjamin devoted much of his time to reading and studying. Since his resources were limited, he could not read as extensively as he wanted to. Benjamin was undaunted by these limitations, however. Instead, he became a closer observer of the natural world. Benjamin drew upon surrounding sources to learn about his own community and even beyond it. Maintaining these resourceful habits, he built upon his supply of general knowledge.

Question

2 Benjamin did not replace his family obligations with his studies, however. He remained devoted to helping his father with farmwork and proved to be as industrious in farming as he was diligent in his pursuit of knowledge. As a matter of fact, by utilizing the springs near the family’s farm, he invented an irrigation system to control the water flow. Because of this creation, his father's farm flourished, even during times of drought.

3 As he continued to develop his reading skills, he grew mentally and soon revealed a gift for analysis. He won the reputation for being a bright mathematician and often solved mathematical puzzles that distinguished scholars gave him. Sometimes Benjamin used his love for analysis in more hands-on projects. In the 1750s he borrowed a watch from a friend. Although he had seen a watch and a sundial, he had never seen a clock before. He deconstructed the friend's watch so that he could study its components. By the age of thirty, Benjamin had created a clock entirely from carved pieces of wood. Painstakingly using only a pocket knife and wood, he carved wheels and gears and completed the clock with such precision that it ran accurately for twenty years. Benjamin's clock, today known as the Banneker Clock, was recognized as the first clock to be built in America, and people even traveled to see his creation. Later, he began his own watch and clock repair business.

4 Benjamin's clock invention launched much speculation into what he would do next. His next interest was in the field of astronomy. He began to see patterns as he gazed at the stars. From these patterns, he made calculations and predictions. To kindle this mental spark, he borrowed books on astronomy and mathematics from a friend, George Ellicott, and Benjamin taught himself about these topics. He learned so much that he accurately predicted a solar eclipse in 1789. This prediction brought even more notoriety to him because it directly contradicted predictions made by well-known mathematicians and astronomers of the time.

5 In 1773, he began to make astronomical calculations for almanacs, which were used frequently by farmers. His almanacs included a variety of information on medicines, tides, and astronomy. Using his own calculations, he compiled and published his first almanac in the 1790s. It was called the Pennsylvania, Delaware, Maryland, and Virginia Almanac and Emphemeris. He even sent a copy of it to Thomas Jefferson, who was United States Secretary of State at the time. With his almanac, he included a letter petitioning Jefferson's help to end slavery.

6 Impressed with Benjamin's abilities, Jefferson recommended Benjamin to become a part of a team of surveyors to plan and lay out the city of Washington, D.C. A Frenchman, Pierre Charles L'Enfant, was the lead architect for the project. After a year, however, L'Enfant was dismissed from the project and took the plans for the city's layout with him when he left the city. Benjamin's memory played an instrumental role, since he was actually able to reproduce the detailed plan in two days from his own memory. He provided a detailed, complete layout of the streets, parks, and major buildings in the city.

7 Benjamin continued to publish his almanacs from 1791 to 1802; these publications helped him to earn the distinction of being one of the first African American experts in science. He also continued to advocate for the elimination of slavery and war during this time. Toward the end of his life, he continued his writing. He wrote a scholarly paper on bees, a study of locust plagues, and letters about injustices toward African Americans. Benjamin Banneker died on October 25, 1806, but he never lost his desire for more knowledge. Benjamin's life served as an example of the importance of self-directed learning and improving the lives of others.

Answer 1

Benjamin Banneker was an influential African American inventor, mathematician, astronomer, and writer, born in 1731 in Ellicott's Mills, Maryland. The eldest of four children, he was raised on a family homestead and displayed exceptional intelligence from a young age. His grandmother supported his curiosity and learning, while he also contributed to farmwork alongside his studies.

Banneker's resourcefulness stood out as he created an irrigation system that significantly enhanced his father's farm productivity, even in drought conditions. His analytical skills became apparent as he excelled in mathematics, earning a reputation for solving complex problems posed by prominent scholars. A pivotal moment occurred when he borrowed a watch, deconstructed it to understand its mechanisms, and eventually crafted the Banneker Clock from wood. This clock became recognized as the first built in America and operated accurately for two decades.

His increasing interest in astronomy led him to study patterns in the night sky. With borrowed books from friend George Ellicott, Banneker self-taught himself enough to successfully predict a solar eclipse in 1789, garnering widespread attention, especially since his prediction contradicted leading astronomers of the time.

In 1773, Banneker began making calculations for farmer’s almanacs, which included significant information on various topics. He published his first almanac in the 1790s, sending a copy to Thomas Jefferson along with a letter advocating for the end of slavery. Jefferson, impressed by Banneker's talents, recommended him for a surveying team that contributed to the planning of Washington, D.C. Despite the lead architect's departure, Banneker recalled the city’s layout from memory, reproducing it accurately in just two days.

Banneker continued to publish his almanacs until 1802 and gained recognition as an early African American expert in science. He wrote scholarly papers on topics such as bees and locust plagues and remained a vocal advocate against slavery and violence until his death on October 25, 1806. His legacy endures as a testament to self-directed learning and the pursuit of knowledge, while actively seeking to improve the conditions of others.
