Sir Edward Sabine was born in 1788 in Dublin, Ireland, to Joseph Sabine, a member of a prominent Anglo-Irish family, and Sarah Hunt. His family had deep military traditions dating back to the 17th century. However, his mother passed away just a month after his birth, and his father soon returned to their home in Tewin, Hertfordshire. One of his older brothers, Joseph Sabine (1770–1837), was a noted naturalist. His early fascination with science was fostered through conversations with Joseph and his brother-in-law, Henry Browne.
Sabine received his education at Marlow and the Royal Military Academy, Woolwich, where he trained in military sciences and engineering. In 1803, at the age of 15, he was commissioned as a second lieutenant in the Royal Artillery. Over the next decade, he steadily rose through the ranks, attaining the rank of captain in 1813 and eventually being promoted to general in 1870.
Sabine's military career was closely linked to his scientific pursuits. He served in Gibraltar during the Peninsular War and later participated in the War of 1812. While en route to Canada in 1813, his ship, the Manchester, was attacked by an American privateer, and he reportedly manned a gun "to good effect." Upon reaching Canada, he saw combat during the Niagara Campaign (1814), where he commanded artillery batteries at the Siege of Fort Erie. Twice mentioned in dispatches, he returned to England following the war and shifted his focus to science.
Sabine became one of the leading geophysicists of his era, specializing in terrestrial magnetism, geodesy, and astronomy. In 1818, he was elected a Fellow of the Royal Society, and that same year, he joined John Ross’s Arctic expedition as an astronomer and scientific officer. His responsibilities included measuring magnetic fields, ocean tides, and atmospheric conditions, as well as recording Greenland’s avian species, leading to the discovery of Sabine’s gull (Larus sabini).
A year later, he accompanied William Edward Parry on another Arctic expedition (1819–1820) to Melville Island, where he conducted magnetic observations and earned the Copley Medal in 1821 for his contributions. During his time in the Arctic, he also produced the North Georgia Gazette and Winter Chronicle, a newspaper for the expedition crew, which was later published in Britain.
Sabine's most enduring scientific achievement was his leadership in the "Magnetic Crusade," a global effort to study terrestrial magnetism. His work in the Arctic and the South Atlantic laid the groundwork for the establishment of a worldwide network of magnetic observatories. Backed by the Royal Society and Sir John Barrow of the Admiralty, he led efforts to build observatories in Toronto, St. Helena, Cape Town, Tasmania, and other British territories.
In 1839, he played a crucial role in securing government support for James Clark Ross’s Antarctic expedition aboard HMS Erebus and HMS Terror. These observatories provided valuable geomagnetic data, helping scientists understand fluctuations in Earth’s magnetic field. He also collaborated with Humphrey Lloyd on a magnetic survey of Ireland (1830–1837), later extending the project to Scotland and England.
Sabine was among the first scientists to identify a correlation between sunspot activity and Earth's magnetic variations. In 1852, analyzing data from the Toronto Magnetic Observatory, he announced that the 11-year sunspot cycle was "absolutely identical" to Earth's geomagnetic cycle. This discovery demonstrated a link between solar activity and Earth’s magnetism, shaping modern space weather research.
He also conducted geodetic studies, refining measurements of Earth's shape using pendulum experiments. These studies, conducted in Africa, the Americas, Greenland, and Spitsbergen, produced the most precise calculation of Earth’s oblateness at the time.
Sabine was instrumental in shaping British scientific institutions. He held multiple leadership roles in the Royal Society, serving as:
- Foreign Secretary (1845)
- Treasurer (1850)
- President (1861–1871)
In addition to his Copley Medal, Sabine was knighted as a Knight Commander of the Order of the Bath (KCB) in 1869. He received honorary doctorates from Oxford and Cambridge, was a member of the Royal Swedish Academy of Sciences, and was elected a Foreign Honorary Member of the American Academy of Arts and Sciences. His extensive writings—103 papers cataloged by the Royal Society—covered a vast range of terrestrial physics, magnetism, and astronomy.
Sabine retired from active military duty in 1877 but continued his scientific pursuits. He passed away on 26 June 1883, at the age of 94, in his home in Richmond, Surrey. He was buried in the family vault in Tewin, Hertfordshire, alongside his wife, Elizabeth Juliana Leeves (1807–1879). Elizabeth, an accomplished scholar, assisted in translating Alexander von Humboldt’s Kosmos and other scientific works into English.
