Harold Dennis Taylor
Harold Dennis Taylor (10 July 1862, in Huddersfield – 26 February 1943) was a British optical designer and inventor, chiefly famous for the invention of the Cooke Triplet, although he was granted about 50 other patents. He was born in 1862 in Huddersfield, attended St Peter's School, York, and began the study of architecture. Circa 1880, he abandoned this to work at Thomas Cooke and Sons of York, a company which produced the finest quality optical instruments, telescopes in particular. As optical manager and chief designer for Thomas Cooke, he won fame for the design and patent in 1893 of the Cooke Triplet and was awarded the Duddell Medal and Prize in 1933. He had married Charlotte Fernandes Barff on 24 July 1888. They had one daughter, Doris, and two sons, Leslie and Edward. Their son Edward Edward is an English given name. It is derived from the Anglo-Saxon name ''Ēadweard'', composed of the elements '' ēad'' "wealth, fortune; prosperous" and '' weard'' "guardia ...

Huddersfield
Huddersfield is a market town in the Kirklees district in West Yorkshire, England. It is the administrative centre and largest settlement in the Kirklees district. The town is in the foothills of the Pennines. The River Holme's confluence into the similar-sized Colne to the south of the town centre which then flows into the Calder in the north eastern outskirts of the town. The rivers around the town provided soft water required for textile treatment in large weaving sheds, this made it a prominent mill town with an economic boom in the early part of the Victorian era Industrial Revolution. The town centre has much neoclassical Victorian architecture, one example is which is a Grade I listed building – described by John Betjeman as "the most splendid station façade in England" – and won the Europa Nostra award for architecture. It hosts the University of Huddersfield and three colleges: Greenhead College, Kirklees College and Huddersfield New College. The town ...

Coxwold
Coxwold is a village and civil parish in the Hambleton District of North Yorkshire, England, in the North York Moors National Park. It is 18 miles north of York and is where the Rev. Laurence Sterne wrote '' A Sentimental Journey''. History The village name is derived from Saxon words ''Cuc'', meaning ''cry'', and ''valt'', meaning ''wood''. The village is mentioned in Domesday Book of 1086 as part of the ''Yarlestre'' hundred by the name of ''Cucvalt''. The lord of the manor at the time of the Norman invasion was ''Kofse'' but the manor passed to ''Hugh, son of Baldric'', and thence to Roger de Mowbray. Before 1158 the manor and lands of Coxwold passed to Thomas de Colville. In return for the lands Thomas had to swear allegiance to Roger de Mowbray. Thomas de Colville's estate included the manors of Yearsley, Coxwold and Oulston as well as other properties and land in York, Thirsk, Everley, Nunwick, Kilburn and Upsland. The Colville shield is proudly displayed at one of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Optics
Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behaviour of visible, ultraviolet, and infrared light. Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties. Most optical phenomena can be accounted for by using the classical electromagnetic description of light. Complete electromagnetic descriptions of light are, however, often difficult to apply in practice. Practical optics is usually done using simplified models. The most common of these, geometric optics, treats light as a collection of rays that travel in straight lines and bend when they pass through or reflect from surfaces. Physical optics is a more comprehensive model of light, which includes wave effects such as diffraction and interference that cannot be ...

Cooke Triplet
The Cooke triplet is a photographic lens designed and patented (patent number GB 22,607) in 1893 by Dennis Taylor who was employed as chief engineer by T. Cooke & Sons of York. It was the first lens system that allowed elimination of most of the optical distortion or aberration at the outer edge of the image. The Cooke triplet is noted for being able to correct the Seidel aberrations. It is recognized as one of the most important objective designs in the field of photography. The lens designed, invented by Dennis Taylor but named for the firm he worked for, consists of three separated lens elements. It has two biconvex lenses on the outer and a biconcave lens in the middle. The design took a new approach to solving the optical design issues, and the design was presented to the Optical Society of London. Design A Cooke triplet comprises a negative flint glass element in the centre with a crown glass element on each side. In this design, the sum of all the curvatures times i ...

Duddell Medal And Prize
The Dennis Gabor Medal and Prize (previously the Duddell Medal and Prize until 2008) is a prize awarded biannually by the Institute of Physics for distinguished contributions to the application of physics in an industrial, commercial or business context. The medal is made of silver and is accompanied by a prize and a certificate. The original Duddell award was instituted by the Council of The Physical Society in 1923 to the memory of William du Bois Duddell, the inventor of the electromagnetic oscillograph. Between 1961 and 1975 it was awarded in alternate odd-numbered years and thereafter annually. In 2008 the award was renamed in honour of Dennis Gabor, the Hungarian – British physicist who developed holography, for which he received the 1971 Nobel Prize in Physics. The prize also switched to being awarded in alternate even-numbered years.

Cooke Optics
Cooke Optics Ltd. is a camera lens manufacturing company based in Leicester. Administratively speaking, Cooke Optics is a spin-off of the company Taylor-Hobson. However, Taylor-Hobson used to be a lens manufacturer and Cooke lenses used to be its sole activity before Taylor-Hobson moved to the market of metrology instruments. Hence the foundation of Cooke Optics can be regarded as the foundation of Taylor, Taylor and Hobson (TTH) in 1886, and Cooke Optics can be regarded as the successor of the original Taylor, Taylor and Hobson business. The name Cooke originally came from the company T. Cooke & Sons of York, a manufacturer of telescopes. The optical manager of that company, H. Dennis Taylor (no relation), devised the Cooke triplet lens in the 1890s. Cooke of York was not interested in the manufacture of camera lenses, and licensed this design and others to TTH. Subsequently many of TTH's own designs, though unconnected with Cooke of York, also carried the Cooke brand. The Cook ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Wilfred Taylor
Edward Wilfred Taylor (29 April 1891-1 November 1980) was a British manufacturer of optical instruments. Biography Taylor was born on 29 April 1891 at 20 Bootham, York, to parents Charlotte Fernandes Taylor and Harold Dennis Taylor (a designer of optical instruments for Thomas Cooke & Sons). He attended a preparatory school at Orelton, Scarborough, before, at age 14, attending Oundle School. He left school in 1908 to take up an apprenticeship at Thomas Cooke & Sons in York. In 1912 he travelled to the US aboard to demonstrate rangefinder equipment to the US government. At the outbreak of the First World War, he enlisted in the 21st Battalion Royal Fusiliers and subsequently commissioned to the Sherwood Foresters as a range finding officer. Taylor subsequently served in the Loyal Regiment (North Lancashire) during the Battle of the Somme, where he was wounded.

1862 Births
Year 186 ( CLXXXVI) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Aurelius and Glabrio (or, less frequently, year 939 ''Ab urbe condita''). The denomination 186 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

People From Huddersfield
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...
