Predicted the existence and location of Neptune, a previously unknown planet, through mathematical calculations, revolutionizing astronomy.

Urbain Le Verrier is perhaps best known for his groundbreaking prediction of the existence and position of Neptune, a feat that cemented his place in the annals of astronomy. Using only mathematics, Le Verrier calculated the coordinates of the then-unknown planet, which were later verified by German astronomer Johann Gottfried Galle, marking one of the most remarkable moments in 19th-century science.

Le Verrier was born on March 11, 1811, in Saint-Lô, Manche, France, to a modest bourgeois family. His parents, Louis-Baptiste Le Verrier and Marie-Jeanne-Josephine-Pauline de Baudre, instilled in him a love for learning, which led him to pursue higher education.

Le Verrier studied at the École Polytechnique, where he briefly delved into chemistry under the guidance of Gay-Lussac. During this period, he wrote papers on the combinations of phosphorus and hydrogen, and of phosphorus and oxygen. However, it was his fascination with astronomy that eventually led him to switch fields and focus on celestial mechanics.

Le Verrier's work in astronomy began in 1839, when he presented his paper "Sur les variations séculaires des orbites des planètes" (On the Secular Variations of the Orbits of the Planets) to the Académie des Sciences. This work addressed the critical question of the stability of the Solar System, a problem first investigated by Laplace.

In 1846, Le Verrier became a member of the French Academy of Sciences, and in 1855, he was elected a foreign member of the Royal Swedish Academy of Sciences. He spent most of his professional life at the Paris Observatory, eventually becoming its director from 1854 to 1870 and again from 1873 to 1877.

Le Verrier's most significant contribution to astronomy came in 1846, when he used mathematical calculations to predict the existence and position of Neptune. He sent his coordinates to Johann Gottfried Galle in Berlin, asking him to verify the prediction. On the same night, Galle discovered Neptune, finding it within 1° of the predicted position.

This remarkable achievement not only validated celestial mechanics but also demonstrated the power of mathematics in understanding the universe. The discovery of Neptune is widely regarded as one of the most significant moments in 19th-century science.

Le Verrier's name is inscribed on the Eiffel Tower, a testament to his contributions to French science. He received numerous honors and awards during his lifetime, including the Copley Medal in 1846 and the Gold Medal of the Royal Astronomical Society in 1868.

Today, Le Verrier's legacy extends beyond his groundbreaking prediction of Neptune. He is recognized as a pioneer in celestial mechanics, and his work has inspired generations of astronomers and mathematicians.

- Le Verrier's prediction of Neptune was initially met with skepticism by some in the scientific community.
- He was a prolific writer, publishing numerous papers on celestial mechanics and astronomy.
- Le Verrier's name is one of the 72 names inscribed on the Eiffel Tower, along with other French scientists and engineers.

Urbain Le Verrier's remarkable prediction of Neptune's existence and position is a testament to the power of human ingenuity and mathematical prowess. His contributions to astronomy and celestial mechanics have had a lasting impact on our understanding of the universe, and his legacy continues to inspire scientists and mathematicians to this day.
