1733 – Jeremiah Dixon born

Jeremiah Dixon was born in Cockfield, in the English county of Durham. He was the fifth of seven children born to George Dixon and Mary Hunter. His father was a wealthy coal mine owner, and Dixon became interested in astronomy and mathematics during his education, interests that would define his career.

He first served as an assistant to Charles Mason in 1761, when the two travelled to Cape of Good Hope to observe the Transit of Venus, but the pair were equals on their most famous deed: surveying the borders of Pennsylvania and Maryland, which would afterwards be known as the Mason-Dixon Line.
