Edmond Halley (1656-1742)
Edmond Halley was a famous English mathematician. He was not just a mathematician and Astronomer, Geophysicist, physicist, and meteorologist too. He set up an observatory in St. Helena island. Edmond was the first man to record the transit of Mercury across the Sun.
He was a fellow of the Royal Society and discoverer of the proper motion of the fixed stars. Edmond computed the periodicity of Halley’s Comet (named after him) by Newton’s Law of Motion.
Time and Place of Birth
Edmond Halley was born on 8 November 1656 in England’s Middlesex region’s Haggerstone, Shoreditch (near London).
Early Life
Edmond was born in a wealthy family; his father Edmond Halley Sr. was a London-based soap maker. Edmond’s mother’s name was Annie Robinson. When he was just ten years old his father lost a big fraction of his property in the Great Fire of London. But still, Edmond was taught by a private tutor at home before going to school.
He was selected as the captain of the school in 1671 while studying at St Paul’s School. Edmond went to college in 1673. At the age of 17, he had a fine collection of astronomical instruments, and by the time he already was a fine astronomer.
Adulthood
In 1680 Edmond began the tour of Europe during his journey he observed a comet near Calais. In 1682 he married Mary Tooke and had three children with her.
Halley helped Newton in Publishing his book Principia. After the death of John Wallis, he was appointed Savilian Professor of Geometry at Oxford in 1704. In 1720 Edmond was chosen the Royal Astronomer.
Death
Edmond Halley died on 14 January 1742 at Greenwich (near London), Kent, England.
Education and Career
Edmond’s first school was St Paul’s School then in 1673, he went to Queen’s College, Oxford. In 1676 he gave up studies and went to St Helena Island in the Southern Hemisphere. In 1678 he returned to England and published his catalog of southern stars.
In the same year, he became a graduate without giving any examination on the order of King Charles II. 1678 was a year of Halley; he was selected as a Fellow of Royal Society and became one of youngest Fellows.

Quotes by Edmond Halley
The sight…is by far the noblest astronomy affords.
Nearer the Gods, no mortal may approach. Halley
In the year 1456…a comet was seen passing retrograde between the earth and the sun…hence I dare venture to foretell that it will return again in the year 1758.
