Galileo
Meaning
of Galilee (from the family name Galilei); famously borne by Galileo Galilei, astronomer who championed the heliocentric model and improved the telescope
The story
Galileo means of Galilee, drawn from the family name Galilei, and in Italy it belongs almost entirely to one man: Galileo Galilei, the Pisan astronomer who turned an improved telescope to the night sky in 1609, found moons circling Jupiter and mountains on our own Moon, and championed the idea that the Earth moves around the Sun, a stand that brought him before the Roman Inquisition and into house arrest for his final years. His first name became shorthand for scientific courage itself. As an American baby name Galileo has always been a rarity, showing its first small stirrings only in the most recent records, which makes it something close to a blank page: a grand, musical Italian name that a child would almost certainly have entirely to themselves.
