John Caldecott
John Caldecott (16 September 1801 – 16 December 1849, Trivandrum) was an East India Company commercial agent, meteorologist and astronomer who worked in the court of the Raja of Travancore at the Trivandrum Observatory. Caldecott was born in Finsbury in London where his father, also John, and mother Susannah lived. He was christened on 1 November 1801 at St Luke's Church. John Caldecott (junior) went to India in 1820 on the ''Mulgrave Castle'' and reached Bombay in May 1821. He worked at Apollo Cotton as an assistant to Daniel West who was a family friend. A relative, William West had an interest in telescopes and microscopes as an evening amusement and this sparked off a scientific interest in John Caldecott. In 1832 he was posted as a commercial agent at the Indian port of Allepey (now Alappuzha) and he saw the need for an astronomical observatory there. This idea was aired in 1836, supported by the Resident Colonel James Stuart Fraser and approved by Raja Swathi Thirunal Rama ...

Trivandrum
Thiruvananthapuram (; ), also known by its former name Trivandrum (), is the capital of the Indian state of Kerala. It is the most populous city in Kerala with a population of 957,730 as of 2011. The encompassing urban agglomeration population is around 1.68 million. Located on the west coast of India near the extreme south of the mainland, Thiruvananthapuram is a major information technology hub in Kerala and contributes 55% of the state's software exports as of 2016. Referred to by Mahatma Gandhi as the "Evergreen city of India", the city is characterised by its undulating terrain of low coastal hills. The present regions that constitute Thiruvananthapuram were ruled by the Ays who were feudatories of the Chera dynasty. In the 12th century, it was conquered by the Kingdom of Venad. In the 18th century, the king Marthanda Varma expanded the territory, founded the princely state of Travancore, and made Thiruvananthapuram its capital. Travancore became the most dominan ...

John Allan Broun
John Allan Broun FRS (21 September 1817 – 22 November 1879) was a Scottish scientist with interests in magnetism, particularly of the earth, and meteorology. Broun studied in Edinburgh University and worked at the observatory in Makerstoun from 1842 to 1849 before moving to India to work in the Kingdom of Travancore. He continued his studies on geo-magnetism in India and was involved in setting up observatories there apart from managing the Napier Museum in Trivandrum. One of the fundamental discoveries he made was that the Earth loses or gains magnetic intensity not locally, but as a whole. He also found that solar activity causes magnetic disturbances. Early years Broun was born in Dumfries where his father ran a school training students intending to join the navy. Broun was educated at Edinburgh University where he was influenced by James D. Forbes. In 1842, there was an interest in magnetic observations and Thomas McDougall Brisbane established an observatory at his home ...

Thomas Glanville Taylor
Thomas Glanville Taylor (22 November 1804 – 4 May 1848) was an English astronomer who worked extensively at the Madras Observatory and produced the Madras Catalogue of Stars from around 1831 to 1839. Life He was the son of Thomas Taylor, assistant at the Royal Greenwich Observatory, and his wife Susannah née Glanville, born at Ashburton, Devon. John Pond, the Astronomer Royal, suggested that the young boy choose a career in astronomy and he joined the observatory in 1820. From August 1822 he was in charge of making transit observations, and his ability was noted by Sir Edward Sabine. Taylor then worked on Stephen Groombridge's star catalogue. Taylor was appointed director of the East India Company's observatory at Madras, arriving there on 15 September 1830. He brought with him new equipment including transit telescopes and a mural circle. He worked with four Indian assistants, who took observations when he went to join the Great Trigonometrical Survey.

Baily's Beads
The Baily's beads effect or diamond ring effect is a feature of total and annular solar eclipses. As the Moon covers the Sun during a solar eclipse, the rugged topography of the lunar limb allows beads of sunlight to shine through in some places while not in others. The effect is named after Francis Baily, who explained the phenomenon in 1836. The diamond ring effect is seen when only one bead is left, appearing as a shining "diamond" set in a bright ring around the lunar silhouette. Lunar topography has considerable relief because of the presence of mountains, craters, valleys, and other topographical features. The irregularities of the lunar limb profile (the "edge" of the Moon, as seen from a distance) are known accurately from observations of grazing occultations of stars. Astronomers thus have a fairly good idea which mountains and valleys will cause the beads to appear in advance of the eclipse. While Baily's beads are seen briefly for a few seconds at the center of the ecli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adolph Theodor Kupffer
Adolph Theodor Kupffer ForMemRS (17 January 1799 Jelgava – 4 June 1865) was a Baltic German (subject of Russian Empire) chemist, and physicist.

Travancore Observatory
The Kingdom of Travancore ( /ˈtrævənkɔːr/), also known as the Kingdom of Thiruvithamkoor, was an Indian kingdom from c. 1729 until 1949. It was ruled by the Travancore Royal Family from Padmanabhapuram, and later Thiruvananthapuram. At its zenith, the kingdom covered most of the south of modern-day Kerala ( Idukki, Kottayam, Alappuzha, Pathanamthitta, Kollam, and Thiruvananthapuram districts, and some portions of Ernakulam district), and the southernmost part of modern-day Tamil Nadu (Kanyakumari district and some parts of Tenkasi district) with the Thachudaya Kaimal's enclave of Irinjalakuda Koodalmanikyam temple in the neighbouring Kingdom of Cochin. However Tangasseri area of Kollam city and Anchuthengu near Attingal in Thiruvananthapuram district, were British colonies and were part of the Malabar District until 30 June 1927, and Tirunelveli district from 1 July 1927 onwards.

Trivandrum Observatory
The Trivandrum Observatory or Thiruvananthapuram Astronomical Observatory is a scientific and astronomical observation station that was established by the Raja of Travancore Swathi Thirunal Rama Varma in 1836-37. The Raja wrote to the British Resident, Colonel James Stuart Fraser, an amateur scientist proposing the establishment of an astronomical observatory. This led to John Caldecott who earlier ran a small personal observatory at Allepey being appointed as the royal astronomer. The observatory was located on the highest point in the city and opposite the palace and was considered important as the magnetic equator at that time passed through Trivandrum. The observatory was designed by Lieutenant W H Horsley of the Madras Engineers. Caldecott also began taking meteorological measurements from July 1837 and expanded to another building in 1842 that housed a Dollond equatorial circle. A ''Travancore Almanac'' was published in 1838. Caldecott travelled to Europe in 1839 to obtai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alexander Von Humboldt
Friedrich Wilhelm Heinrich Alexander von Humboldt (14 September 17696 May 1859) was a German polymath, geographer, naturalist, explorer, and proponent of Romantic philosophy and science. He was the younger brother of the Prussian minister, philosopher, and linguist Wilhelm von Humboldt (1767–1835). Humboldt's quantitative work on botanical geography laid the foundation for the field of biogeography. Humboldt's advocacy of long-term systematic geophysical measurement laid the foundation for modern geomagnetic and meteorological monitoring. Between 1799 and 1804, Humboldt travelled extensively in the Americas, exploring and describing them for the first time from a modern Western scientific point of view. His description of the journey was written up and published in several volumes over 21 years. Humboldt was one of the first people to propose that the lands bordering the Atlantic Ocean were once joined (South America and Africa in particular). Humboldt resurrected the use ...
