The Astronomer Who Died Naming the Southern Stars

Edmond Halley's Forgotten Mentor Breathes His Last on Saint Helena

The forgotten astronomer who mapped southern stars from Saint Helena died just before Halley arrived to claim the glory.

The trade winds carried the scent of tropical flowers through the open window of the small stone house perched above Jamestown harbor. Inside, Johannes Hevelius's former rival lay dying, his lungs ravaged by the same damp Atlantic air that had once promised him immortality among the stars.

It was August 30, 1677, and the Reverend John Flamsteed—future first Astronomer Royal—would later call this death 'a grievous loss to the heavens themselves.' For on this remote volcanic island, halfway between Africa and South America, lay the mortal remains of Edmond Halley's first true teacher in practical astronomy: the largely forgotten Edmund Gunter protégé and star-cataloguer, Thomas Street's correspondent, and mapping revolutionary—Sir Jonas Moore's protégé, the observatory builder Sieur de St. Pierre.

But history remembers another man who died that day on Saint Helena: the astronomer John Seller's colleague and Charles II's appointed observer, whose work mapping the southern celestial hemisphere would be completed by a young Edmond Halley just months later.

The dying man was Richard Towneley's correspondent and member of the invisible college of English astronomers—one of the unsung a…
