Frances Mary Hamer
Frances Mary Hamer (1894–1980) was a British chemist who specialized in the sensitization compounds used for photographic processing for which she held many patents. She was very active in the Allied efforts to enhance aerial photography during World War I. Life Frances was born on 14 October 1894 to Sir William Heaton Hamer (1862–1936) and Agnes Conan in Kentish Town, London. Her father studied medicine at Cambridge and in 1912 was named Medical Officer of Health of the London County Council. Education Hamer attended the same school as her mother and aunts on both sides of the family, the North London Collegiate School. Hamer was named after the founder of the school, and her godmother, educator Frances Mary Buss. Hamer graduated in 1916 and that same year, she read chemistry at Girton College, Cambridge. However, at that time, women were not allowed to earn college degrees at Cambridge. She went on to earn her doctorate in chemistry in 1924 from the University of London ...

Kentish Town
Kentish Town is an area of northwest London, England in the London Borough of Camden, immediately north of Camden Town. Less than four miles north of central London, Kentish Town has good transport connections and is situated close to the open spaces of Hampstead Heath. Toponymy The name of Kentish Town is probably derived from ''Ken-ditch'' or ''Caen-ditch'', meaning the "bed of a waterway" and is otherwise unrelated to the English county of Kent. In researching the meaning of ''Ken-ditch'', it has also been noted that ''ken'' is the Celtic word for both "green" and "river", while ''ditch'' refers to the River Fleet, now a subterranean river. However, another theory is the name comes from its position near the Fleet; it has been suggested that Kentish Town, which lies in between two forks of the Fleet, takes its name from ''cant'' or ''cantle'' (from the Middle English meaning "corner"). History Kentish Town was originally a small settlement on the River Fleet (the waterwa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kodak Harrow
The Kodak Works, Harrow was a photographic manufacturing plant and research and development centre on Headstone Drive, Harrow, North West London. Built by the American Kodak company in 1890, it was their largest factory in the United Kingdom and at its peak in the mid-20th century employed up to 6,000 workers. Production of photographic film ended in 2005 and the plant closed its doors in 2016. History The factory was built in what was then farmland in the hamlet of Wealdstone in Middlesex, directly to the west of the railway line that stops at nearby Harrow & Wealdstone station. Kodak purchased of land and the plant opened in 1891, Kodak's first manufacturing facility outside the United States where production was running in Rochester, New York. Initially the factory developed and printed photographs of clients. In the next 20 years the factory expanded. Eventually film rolls and photographic paper were also being produced at the plant. Added to the factory was a museum, sport ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

WorldCat
WorldCat is a union catalog that itemizes the collections of tens of thousands of institutions (mostly libraries), in many countries, that are current or past members of the OCLC global cooperative. It is operated by OCLC, Inc. Many of the OCLC member libraries collectively maintain WorldCat's database, the world's largest bibliographic database. The database includes other information sources in addition to member library collections. OCLC makes WorldCat itself available free to libraries, but the catalog is the foundation for other subscription OCLC services (such as resource sharing and collection management). WorldCat is used by librarians for cataloging and research and by the general public. , WorldCat contained over 540 million bibliographic records in 483 languages, representing over 3 billion physical and digital library assets, and the WorldCat persons dataset (Data mining, mined from WorldCat) included over 100 million people.

Cyanine
Cyanines, also referred to as tetramethylindo(di)-carbocyanines are a synthetic dye family belonging to the polymethine group. Although the name derives etymologically from terms for shades of blue, the cyanine family covers the electromagnetic spectrum from near IR to UV. Chemically, cyanines are a conjugated system between two nitrogen atoms; in each resonance structure, exactly one nitrogen atom is oxidized to an iminium. Typically, they form part of a nitrogenous heterocyclic system. The main application for cyanine dyes is in biological labeling. Nevertheless, there is a wide literature on both their synthesis and uses, and cyanines are common in some CD and DVD media. Structure Cyanines have been classified in many ways: * ''Streptocyanines'' or ''open chain cyanines'': : R2N+=CH H=CH'n''-NR2 (I) * ''Hemicyanines'': : Aryl=N+=CH H=CH'n''-NR2 (II) * ''Closed chain cyanines'': :Aryl=N+=CH H=CH'n''-N=Aryl (III) Additionally, these classes are recognized: * ...

Royal Photographic Society
The Royal Photographic Society of Great Britain, commonly known as the Royal Photographic Society (RPS), is one of the world's oldest photographic societies. It was founded in London, England, in 1853 as the Photographic Society of London with the objective of promoting the art and science of photography, and in 1853 received Monarchy of the United Kingdom, royal patronage from Queen Victoria and Albert, Prince Consort, Prince Albert. A change to the society's name to reflect the patronage was, however, not considered expedient at the time. In 1874, it was renamed the Photographic Society of Great Britain, and only from 1894 did it become known as the Royal Photographic Society of Great Britain, a title which it continues to use today. On 25 June 2019, the Duchess of Cambridge, now Catherine, Princess of Wales, became the Society's Patron, taking over from Queen Elizabeth II who had been patron since 1952.

Chemical Society
The Chemical Society was a scientific society formed in 1841 (then named the Chemical Society of London) by 77 scientists as a result of increased interest in scientific matters. Chemist Robert Warington was the driving force behind its creation. History One of the aims of the Chemical Society was to hold meetings for "the communication and discussion of discoveries and observations, an account of which shall be published by the Society". In 1847, its importance was recognised by a Royal Charter, which added to its role in the advancement of science, the development of chemical applications in industry. Its members included eminent chemists from overseas including August Wilhelm von Hofmann, who became its president in 1861. Membership was open to all those interested in chemistry, but fellowship was for long restricted to men. In 1904, Edith Humphrey, thought to be the first British woman to gain a doctorate in chemistry (at the University of Zurich), was one of nineteen women ch ...
