Thomas Grubb
Thomas Grubb (4 August 1800 – 16 September 1878) was an Irish optician and founder of the Grubb Telescope Company. He was born near Portlaw, County Waterford, Ireland, the son of William Grubb Junior, a prosperous Quaker farmer and his second wife, Eleanor Fayle. Thomas started out in 1830 in Dublin as a metal billiard-table manufacturer. He diversified into making telescopes and erected a public observatory near his factory at 1 Upper Charlemont Street, Portobello, Dublin. As makers of some of the largest and best-known telescopes of the Victorian era, the company was at the forefront of optical and mechanical engineering. His innovations for large telescopes included clock-driven polar mounts, whiffletree mirror mounting cells and Cassegrain reflector optics. Later, the manufacturing firm changed its name to Grubb-Parsons in 1925. Works Thomas Grubb's reputation as a competent telescope maker began to spread as he offered his talents to the Irish astronomical comm ...

Mount Jerome Cemetery
Mount Jerome Cemetery & Crematorium () is situated in Harold's Cross on the south side of Dublin, Ireland. Since its foundation in 1836, it has witnessed over 300,000 burials. Originally an exclusively Protestant cemetery, Roman Catholics have also been buried there since the 1920s. History The name of the cemetery comes from an estate established there by the Reverend Stephen Jerome, who in 1639 was vicar of St. Kevin's Parish. At that time, Harold's Cross was part of St. Kevin's Parish. In the latter half of the 17th century, the land passed into the ownership of the Earl of Meath, who in turn leased plots to prominent Dublin families. A house, Mount Jerome House, was constructed in one of these plots, and leased to John Keogh. In 1834, after an aborted attempt to set up a cemetery in the Phoenix Park, the General Cemetery Company of Dublin bought the Mount Jerome property, "for establishing a general cemetery in the neighbourhood of the city of Dublin".

Allies Of World War I
The Allies or the Entente (, ) was an international military coalition of countries led by the French Republic, the United Kingdom, the Russian Empire, the United States, the Kingdom of Italy, and the Empire of Japan against the Central Powers of the German Empire, Austria-Hungary, the Ottoman Empire, and the Kingdom of Bulgaria in World War I (1914–1918).

As the war progressed, each coalition added new members. Japan joined the Entente in 1914 and, despite proclaiming its neutrality at the beginning of the war, Italy also joined the Entente in 1915. The term "Allies" became more widely used than "Entente", although the United Kingdom, Fran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Howard Grubb
Sir Howard Grubb (28 July 1844 – 16 September 1931) was an Irish optical engineer. He was head of a family firm that made large optical telescopes, telescope drive controls, and other optical instruments. He is also noted for his work to perfect the periscope and invent the reflector sight. Biography Howard Grubb was one of eight children of Thomas Grubb, founder of the Grubb Telescope Company, and his wife, Sarah. Howard developed an early interest in optics. He began his studies in Trinity College Dublin in 1863 but did not complete his degree.

Magnetometer
A magnetometer is a device that measures magnetic field or magnetic dipole moment. Different types of magnetometers measure the direction, strength, or relative change of a magnetic field at a particular location. A compass is one such device, one that measures the direction of an ambient magnetic field, in this case, the Earth's magnetic field. Other magnetometers measure the magnetic dipole moment of a magnetic material such as a ferromagnet, for example by recording the effect of this magnetic dipole on the induced current in a coil. The invention of the magnetometer is usually credited to Carl Friedrich Gauss in 1832. Earlier, more primitive instruments were developed by Christopher Hansteen in 1819, and by William Scoresby by 1823. Magnetometers are widely used for measuring the Earth's magnetic field, in geophysical surveys, to detect magnetic anomalies of various types, and to determine the dipole moment of magnetic materials. In an aircraft's attitude and heading ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Melbourne Observatory
Melbourne Observatory is an observatory located on a hill adjacent to the Royal Botanic Gardens Victoria. The observatory commenced operations in 1863 and was decommissioned from official Government work in 1945. The observatory has since continued as an astronomical observatory and remains open to the public. Melbourne Observatory is also permanently on the Australian National Heritage List under 'Melbourne's Domain Parkland and Memorial Precinct' since early 2018. History Melbourne Observatory was founded in 1862 to serve as a scientific research institution for the rapidly growing city of Melbourne, the capital of the colony of Victoria. The observatory was tasked by the Victorian government with maintaining an accurate time reference for the colony through observations of stars using a transit telescope as well as general astronomical research. The idea for a Melbourne Observatory was first proposed by English astronomer William Parkinson Wilson in a paper read before The ...
