Edmund Halley o Edmond Halley. Hijo de un acaudalado fabricante de jabón, nació en Haggerston, cerca de Londres en 1656. A los 17 años se trasladó a Oxford.
Desde muy joven sintió una gran inclinación por las matemáticas e interesado en la investigación de los cielos por el astrónomo real, John Flamsteed . En 1676 publicó en "Philosophical Transactions" una disertación sobre la teoría de los planetas, y en el mismo año se trasladó a la isla de Santa Helena para observar las estrellas del cielo austral y hacer un catálogo de las mismas: se llevó relojes, micrómetros y un gran telescopio refractor de 7,3 metros de longitud que utilizó con gran provecho, pese a las malas condiciones atmosféricas; el resultado fue el "Catalogus stellarun australium", publicado en Londres en 1679, obra que tabula la posición de 341 estrellas australes.
Amigo de Isaac Newton , le animó a escribir su "Principia Mathematica". Es posible que en la época de Newton no se hubieran publicado, de no haber sido por su amistad con Halley, pues se sabe que al primero no le preocupaba la publicación de su obra. Halley no solo pagó la impresión sino que se encargó de corregir pruebas y de otras labores editoriales. El libro original se vendió a las librerías por seis chelines, sin encuadernar.
