About the author

Born in Alnwick, England, on 27 July 1801, George Biddell Airy studied at Trinity College, Cambridge, where he rose quickly through the academic ranks. He served as Lucasian Professor of Mathematics and then as Plumian Professor of Astronomy before becoming Astronomer Royal in 1835.

Airy is remembered for both scientific insight and institution-building. He worked on planetary motion, optics, tides, and the shape and density of the Earth, and his name lives on in the "Airy disk" of optical theory. As Astronomer Royal, he reorganized work at Greenwich and oversaw instruments and observations that helped fix Greenwich as the prime meridian.

He remained Astronomer Royal until 1881 and was one of the central figures of Victorian science. Born in 1801 and dying in 1892, he belonged to an era when astronomy, mathematics, navigation, and government science were closely linked, and his life shows how much careful observation could shape the modern world.
