Benjamin Banneker was a renowned African American Astronomer, Surveyor, Mapmaker, and Clockmaker who lived in Baltimore County, Maryland. He was born to Mary Banneky, a Dutch-African American woman, and Robert Banneky, a former Slave from Guinea. Banneker's early life was influenced by his grandmother, Molly Welsh, who taught him how to read and write, and his friendship with Peter Heinrich, a German-American Tobacco farmer who introduced him to Astronomy and Mathematics. Banneker's interest in Astronomy was further sparked by the Transit of Venus across the Sun in 1769, which he observed using a Telescope made by James Ferguson.

● Early Life and Education

Banneker's early education was largely self-directed, with influences from Isaac Newton's Philosophiæ Naturalis Principia Mathematica and Euclid's Elements. He also studied the works of Leonhard Euler, Pierre-Simon Laplace, and Joseph-Louis Lagrange, which helped him develop his skills in Mathematics and Astronomy. Banneker's knowledge of Astronomy was further enhanced by his observations of the Solar System, including the Planets Jupiter, Saturn, and Uranus, which were discovered by William Herschel. He also corresponded with Thomas Jefferson, who was impressed by Banneker's knowledge of Astronomy and Mathematics, and Marquis de Lafayette, who supported Banneker's efforts to promote Abolitionism.

● Career and Achievements

Banneker's career as a Surveyor and Mapmaker began in 1753, when he helped Andrew Ellicott survey the Boundary between Maryland and Pennsylvania. He also worked on the Survey of the District of Columbia, which was led by Pierre Charles L'Enfant. Banneker's skills in Astronomy and Mathematics made him an invaluable asset to the Survey team, which included Alexander Hamilton, Thomas Jefferson, and James Madison. Banneker's achievements were recognized by the American Philosophical Society, which elected him as a member in 1791, and the French Academy of Sciences, which awarded him a Medal for his contributions to Astronomy.

● Astronomical Contributions

Banneker's contributions to Astronomy include his predictions of Eclipses, which were published in his Almanac from 1792 to 1797. He also calculated the Orbit of Halley's Comet, which was visible in the Sky in 1758 and 1835. Banneker's knowledge of Astronomy was influenced by the works of Nicolaus Copernicus, Galileo Galilei, and Johannes Kepler, who developed the Heliocentric Model of the Solar System. He also corresponded with William Herschel, who discovered Uranus and two moons of Uranus, and Caroline Herschel, who discovered several Comets and Asteroids.

● Surveyor and Mapmaker

Banneker's work as a Surveyor and Mapmaker included the creation of Maps of the District of Columbia, which were used by George Washington and Thomas Jefferson to plan the City of Washington, D.C.. He also worked on the Survey of the Potomac River, which was led by George Mason and James Monroe. Banneker's skills in Surveying and Mapmaking were influenced by the works of Gerardus Mercator, who developed the Mercator Projection, and Abraham Ortelius, who created the first World Atlas. He also used the Theodolite, a Surveying instrument developed by Jesse Ramsden, to measure Angles and Distances.

● Legacy and Recognition

Banneker's legacy as a African American Astronomer, Surveyor, and Mapmaker has been recognized by the National Aeronautics and Space Administration (NASA), which named a Crater on the Moon after him. He has also been honored by the United States Postal Service, which issued a Stamp in his honor in 1980. Banneker's contributions to Astronomy and Surveying have been recognized by the American Astronomical Society, which awarded him a Posthumous Award in 1998, and the National Society of Professional Surveyors, which named an Award after him. Banneker's life and work have also been celebrated by the Benjamin Banneker Historical Park and Museum in Baltimore County, Maryland, which was established in 1998 to promote his legacy and contributions to African American History and American History.
