Happy Teachers Day to All

LIS Cafe Salute to all Teachers 

Teachers' Day is a special day for the appreciation of teachers, and may include celebrations to honor them for their special contributions in a particular field area, or the community in general.

The idea of celebrating Teachers' Day took root in many countries during the 19th century; in most cases, they celebrate a local educator or an important milestone in education (for example, Argentina has commemorated Domingo Faustino Sarmiento's death on 11 September) since 1915. While India traditionally celebrates Guru Purnima, an Indian and Nepalese festival dedicated to spiritual and academic teachers which is celebrated on the full moon day (Purnima) in the Hindu month of Ashadha (June–July) as it is known in the Hindu calendar of India and Nepal. The birthday of Dr. Sarvepalli Radhakrishnan (5 September) is also celebrated as Teacher's Day in India since 1962.This is the primary reason why countries celebrate this day on different dates, unlike many other International Days.

  Sarvepalli Radha krishnan (5 September 1888 – 17 April 1975) was an Indian philosopher and statesman who was the first Vice President of India (1952–1962) and the second President of India from 1962 to 1967. One of India's most distinguished twentieth-century scholars of comparative religion and philosophy,his academic appointments included the King George V Chair of Mental and Moral Science at the University of Calcutta (1921–1932) and Spalding Professor of Eastern Religion and Ethics at University of Oxford (1936–1952).Source: Wikipedia

Rabindranath Tagore (7 May 1861 – 7 August 1941), sobriquet Gurudev, was a Bengali polymath who reshaped Bengali literature and music, as well as Indian art with Contextual Modernism in the late 19th and early 20th centuries. Author of Gitanjali and its "profoundly sensitive, fresh and beautiful verse",  he became the first non-European to win the Nobel Prize in Literature in 1913. Tagore's poetic songs were viewed as spiritual and mercurial; however, his "elegant prose and magical poetry" remain largely unknown outside Bengal.  He is sometimes referred to as "the Bard of Bengal".Source: Wikipedia

Melville Louis Kossuth (Melvil) Dewey (December 10, 1851 – December 26, 1931) was an American librarian and educator, inventor of the Dewey Decimal system of library classification, and a founder of the Lake Placid Club.Melville Louis Kossuth (Melvil) Dewey was a pioneer in American librarianship and an influential figure in the development of libraries in America in the late 19th and early the 20th century. He is best known for the decimal classification system that many public and school libraries use. Among his other innovations was the idea of a state library operating as the controller of the state's school and public library services. In Boston, Massachusetts, he founded the Library Bureau, a private company "for the definite purpose of furnishing libraries with equipment and supplies of unvarying correctness and reliability." Its investigative unit, devoted to studying the best practices of library loss-management, circulation and data retention, recovered 3,000 books in its first year of existence. Dewey's Library Bureau company is also said to have introduced hanging vertical files, first seen at the Columbian Exposition of 1893 in Chicago. In 1905, Dewey established the American Library Institute which was an organization conceived to provide for the investigation, study and discussion of issues within the field of library theory and practice.

Albert Einstein (14 March 1879 – 18 April 1955) was a German-born theoretical physicist. Einstein developed the theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics). Einstein's work is also known for its influence on the philosophy of science. Einstein is best known by the general public for his mass–energy equivalence formula E = mc2 (which has been dubbed "the world's most famous equation"). He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect", a pivotal step in the evolution of quantum theory.Source: Wikipedia

Avul Pakir Jainulabdeen Abdul Kalam, better known as A. P. J. Abdul Kalam (15 October 1931 – 27 July 2015), was the 11th President of India from 2002 to 2007. A career scientist turned statesman, Kalam was born and raised in Rameswaram, Tamil Nadu, and studied physics and aerospace engineering. He spent the next four decades as a scientist and science administrator, mainly at the Defence Research and Development Organisation (DRDO) and Indian Space Research Organisation (ISRO) and was intimately involved in India's civilian space programme and military missile development efforts.Source: Wikipedia

Siyali Ramamrita Ranganathan (S.R.R) (August 1892 – 27 September 1972) was a mathematician and librarian from India. His most notable contributions to the field were his five laws of library science and the development of the first major faceted classification system, the colon classification. He is considered to be the father of library science, documentation, and information science in India and is widely known throughout the rest of the world for his fundamental thinking in the field. His birthday is observed every year as the National Library Day in India.Source: Wikipedia

  

Charles Ammi Cutter (March 14, 1837 – September 6, 1903) was an American librarian. Cutter was born in Boston, Massachusetts. His aunt was an employee of the regional library in Boston. In 1856 Cutter was enrolled into Harvard Divinity School. He was appointed assistant librarian of the divinity school while still a student there and served in that capacity from 1857 to 1859. During that time, Cutter began designing a distinct cataloging schema for the library's outdated system. The catalog, dating from 1840, had a lack of order after the acquisition of 4,000 volumes from the collection of Professor Gottfried Christian Friedrich Lücke of University of Göttingen, which added much depth to the Divinity School Library's collection.Source: Wikipedia

Claude Elwood Shannon (April 30, 1916 – February 24, 2001) was an American mathematician, electrical engineer, and cryptographer known as "the father of information theory". Shannon is noted for having founded information theory with a landmark paper, A Mathematical Theory of Communication, that he published in 1948. He is, perhaps, equally well known for founding digital circuit design theory in 1937, when—as a 21-year-old master's degree student at the Massachusetts Institute of Technology (MIT)—he wrote his thesis demonstrating that electrical applications of Boolean algebra could construct any logical, numerical relationship. Shannon contributed to the field of cryptanalysis for national defense during World War II, including his fundamental work on codebreaking and secure telecommunications.Source: Wikipedia

Charles Walton (1921 – November 6, 2011 is best known as the first patent holder for the RFID (radio frequency identification) device. Many individuals contributed to the invention of the RFID, but Walton was awarded ten patents in all for various RFID-related devices, including his key 1973 design for a "Portable radio frequency emitting identifier". This patent was awarded in 1983, and was the first to bear the acronym "RFID".

Charles Walton grew up in Maryland and New York State, and graduated from George School in 1939. He graduated from Cornell University in 1943 with a degree in Electrical engineering, and received a master's degree from Stevens Institute of Technology. Source: Wikipedia

Sir Jagdish Chandra Bose (30 November 1858 – 23 November 1937), also spelled Jagdish and Jagadis, was a Bengali polymath, physicist, biologist, biophysicist,botanist and archaeologist, and an early writer of science fiction.[8] Living in British India, he pioneered the investigation of radio and microwave optics, made significant contributions to plant science, and laid the foundations of experimental science in the Indian subcontinent. IEEE named him one of the fathers of radio science. Bose is considered the father of Bengali science fiction, and also invented the crescograph, a device for measuring the growth of plants. A crater on the moon has been named in his honour.Source: Wikipedia
