John Birmingham (astronomer)
John Birmingham (1816–1884) was an Irish astronomer, amateur geologist, polymath and poet. He spent six or seven years travelling widely in Europe where he became proficient in several languages. In 1866 he discovered the recurrent nova T Coronae Borealis. He studied and wrote articles on planets, meteor showers and sunspots.
He was born to Edward Birmingham and Elly Bell and grew up on the Millbrook Estate outside Milltown, County Galway and was educated at St. Jarlath's College in Tuam. Between 1844 and 1854 he spent several years travelling through Europe, and is thought to have studied in Berlin. In 1846 and 1847 he was active in Famine relief around Tuam. In 1852 he visited Rome. When he returned home in 1854 he built up a network of newspapers and magazines to which he started contributing articles on scientific and other matters. He first attracted attention with his articles on sedimentary rocks in the west of Ireland which he contributed to the Journal of the Geological Society of Dublin.
He inherited part of the Millbrook estate, which was scattered across Galway and Mayo, in 1865, and settled at Millbrook House with two elderly aunts and a maternal uncle, Arthur Bell, who assisted him in his research. He became known as a kindly landlord but also as a scholar and intellectual. From 1858 He started contributing notes on astronomy to local newspapers. At Millbrook he built what the Tuam Herald called a large wooden house with a sliding roof, which formed his first observatory. On 12 May 1866 he discovered the variable star T Coronae Borealis in the constellation Corona Borealis. This success of this find led him to acquire a powerful new telescope from Thomas Cooke of York (which cost £120), fitted with a lens made by Thomas Grubb of Dublin.
Birmingham Lunar Crater
In 1866, he wrote an essay about the disappearance of a crater on the surface of the moon and the subsequent appearance of a vast luminous cloud in its place. In its review of the essay, the Irish Times commented: “We know of no paper which contains an equal amount of learning in so brief a space, in so charming a style and manner, and stamps him as a man of learning, eloquence and refined taste combined with genius.” In 1883, the Royal Irish Academy presented Birmingham with a gold medal for his valuable contributions to the society's transactions.
Birmingham Lunar Crater is located near the northern limb of the Moon, and so is viewed from the Earth at a low angle. All that survives of the original formation is an irregular perimeter of low, indented ridges surrounding the lava-resurfaced interior. The inner floor is marked by several tiny craterlets, and the surface is unusually rough for a walled plain. The low angle of illumination allows fine details of this boulder-strewn field to be seen more clearly. The Birmingham formation lies just to the north of the Mare Frigoris, and to the east of the W. Bond walled-plain.
Study of red stars
John Birmingham, using a 4.5-inch (110 mm) Cooke refractor, made a special study of red stars and revised and extended Schjellerup's Catalogue of Red Stars. Six hundred and fifty eight of these objects were included.
He presented this work to the Royal Irish Academy in 1876 and was awarded the Cunningham Medal. In 1881 he discovered a deep red star in Cygnus constellation. This star is named after him. Other subjects on which he published articles included meteor showers, the transit of Venus and sunspots. He had correspondence with other leading astronomers.
John Birmingham was an only child. He never married but he was reputed to have fathered a daughter. He died at the Millbrook Estate in 1884 and his house was left to ruin. All that remains of his possessions is his telescope, which is on display at the Milltown community museum.
In his lifetime however he was well known and well respected, Robert Ball made reference to Birmingham's Observatory in one of his books and John, like William E. Wilson had numerous contacts at Dunsink Observatory.
