Thomas Alva Edison 1847-1931

Thomas Alva Edison 1847-1931, American inventor, b. Milan, Ohio. A genius in the practical application of scientific principles, Edison was one of the greatest and most productive inventors of his time, but his formal schooling was limited to three months in Port Huron, Mich., in 1854. For several years he was a newsboy on the Grand Trunk RR, and it was during this period that he began to suffer from deafness, which was to increase throughout his life. He later worked as a telegraph operator in various cities.

Edison's first inventions were the transmitter and receiver for the automatic telegraph, the quadruplex system of transmitting four simultaneous messages, and an improved stock-ticker system. In 1877 he invented the carbon telephone transmitter (see microphone ) for the Western Union Telegraph Company. His phonograph (patented 1878) was notable as the first successful instrument of its kind.

In 1879, Edison created the first commercially practical incandescent lamp (with a carbon filament). For use with it he developed a complete electrical distribution system for light and power, including generators, motors, light sockets with the Edison base, junction boxes, safety fuses, underground conductors, and other devices. The crowning achievement of his work in this field was the Pearl St. plant (1881-82) in New York City, the first permanent central electric-light power plant in the world. He also built and operated (1880) an experimental electric railroad, and produced a superior storage battery of iron and nickel with an alkaline electrolyte.

Other significant inventions include the Kinetoscope, or peep-show machine. Edison later demonstrated experimentally the synchronization of motion pictures and sound, and talking pictures were based on this work. During World War I he helped to develop the manufacture in the United States of chemicals previously imported; he also served as head of the U.S. navy consulting board concerned with ship defenses against torpedoes and mines. Edison later worked on the production of rubber from American plants, notably goldenrod.

Edison held over 1,300 U.S. and foreign patents, and his workshops at Menlo Park (1876) and West Orange, N.J. (1887), were significant as forerunners of the modern industrial research laboratory in which teams of workers, rather than a lone inventor, systematically investigate a given subject. An Edison memorial tower and light was erected (1938) in Menlo Park, N.J.; Edison's laboratory and other buildings associated with his career are preserved or replicated in Greenfield Village . Some of his various companies were consolidated to form the General Electric Company (GE).

Sir Alexander Fleming

Sir Alexander Fleming was born at Lochfield near Darvel in Ayrshire, Scotland on August 6th, 1881. He attended Louden Moor School, Darvel School, and Kilmarnock Academy before moving to London where he attended the Polytechnic. He spent four years in a shipping office before entering St. Mary's Medical School, London University. He qualified with distinction in 1906 and began research at St. Mary's under Sir Almroth Wright, a pioneer in vaccine therapy. He gained M.B., B.S., (London), with Gold Medal in 1908, and became a lecturer at St. Mary's until 1914. He served throughout World War I as a captain in the Army Medical Corps, being mentioned in dispatches, and in 1918 he returned to St.Mary's. He was elected Professor of the School in 1928 and Emeritus Professor of Bacteriology, University of London in 1948. He was elected Fellow of the Royal Society in 1943 and knighted in 1944.

Early in his medical life, Fleming became interested in the natural bacterial action of the blood and in antiseptics. He was able to continue his studies throughout his military career and on demobilization he settled to work on antibacterial substances which would not be toxic to animal tissues. In 1921, he discovered in «tissues and secretions» an important bacteriolytic substance which he named Lysozyme. About this time, he devised sensitivity titration methods and assays in human blood and other body fluids, which he subsequently used for the titration of penicillin. In 1928, while working on influenza virus, he observed that mould had developed accidently on a staphylococcus culture plate and that the mould had created a bacteria-free circle around itself. He was inspired to further experiment and he found that a mould culture prevented growth of staphylococci, even when diluted 800 times. He named the active substance penicillin.

Sir Alexander wrote numerous papers on bacteriology, immunology and chemotherapy, including original descriptions of lysozyme and penicillin. They have been published in medical and scientific journals.

Fleming, a Fellow of the Royal College of Surgeons (England), 1909, and a Fellow of the Royal College of Physicians (London), 1944, has gained many awards. They include Hunterian Professor (1919), Arris and Gale Lecturer (1929) and Honorary Gold Medal (1946) of the Royal College of Surgeons; Williams Julius Mickle Fellowship, University of London (1942); Charles Mickle Fellowship, University of Toronto (1944); John Scott Medal, City Guild of Philadelphia (1944); Cameron Prize, University of Edinburgh (1945); Moxon Medal, Royal College of Physicians (1945); Cutter Lecturer, Harvard University (1945); Albert Gold Medal, Royal Society of Arts (1946); Gold Medal, Royal Society of Medicine (1947); Medal for Merit, U.S.A. (1947); and the Grand Cross of Alphonse X the Wise, Spain (1948).

He served as President of the Society for General Microbiology, he was a Member of the Pontifical Academy of Science and Honorary Member of almost all the medical and scientific societies of the world. He was Rector of Edinburgh University during 1951-1954, Freeman of many boroughs and cities and Honorary Chief Doy-gei-tau of the Kiowa tribe. He was also awarded doctorate, honoris causa, degrees of almost thirty European and American Universities.

In 1915, Fleming married Sarah Marion McElroy of Killala, Ireland, who died in 1949. Their son is a general medical practitioner.

Fleming married again in 1953, his bride was Dr. Amalia Koutsouri-Voureka, a Greek colleague at St. Mary's.

In his younger days he was a keen member of the Territorial Army and he served from 1900 to 1914 as a private in the London Scottish Regiment.

Dr Fleming died on March 11th in 1955 and is buried in St. Paul's Cathedral.

Abraham Lincolin

Lincoln warned the South in his Inaugural Address: "In your hands, my dissatisfied fellow countrymen, and not in mine, is the momentous issue of civil war. The government will not assail you.... You have no oath registered in Heaven to destroy the government, while I shall have the most solemn one to preserve, protect and defend it."

Abraham Lincoln, the 16th president of the United States, guided his country through the most devastating experience in its national history--the CIVIL WAR. He is considered by many historians to have been the greatest American president.

The son of a Kentucky frontiersman, Lincoln had to struggle for a living and for learning. Five months before receiving his party's nomination for President, he sketched his life:

"I was born Feb. 12, 1809, in Hardin County, Kentucky. My parents were both born in Virginia, of undistinguished families--second families, perhaps I should say. My mother, who died in my tenth year, was of a family of the name of Hanks.... My father ... removed from Kentucky to ... Indiana, in my eighth year.... It was a wild region, with many bears and other wild animals still in the woods. There I grew up.... Of course when I came of age I did not know much. Still somehow, I could read, write, and cipher ... but that was all."

Lincoln made extraordinary efforts to attain knowledge while working on a farm, splitting rails for fences, and keeping store at New Salem, Illinois. He was a captain in the Black Hawk War, spent eight years in the Illinois legislature, and rode the circuit of courts for many years. His law partner said of him, "His ambition was a little engine that knew no rest."

He married Mary Todd, and they had four boys, only one of whom lived to maturity. In 1858 Lincoln ran against Stephen A. Douglas for Senator. He lost the election, but in debating with Douglas he gained a national reputation that won him the Republican nomination for President in 1860.

As President, he built the Republican Party into a strong national organization. Further, he rallied most of the northern Democrats to the Union cause. On January 1, 1863, he issued the Emancipation Proclamation that declared forever free those slaves within the Confederacy.

Lincoln never let the world forget that the Civil War involved an even larger issue. This he stated most movingly in dedicating the military cemetery at Gettysburg: "that we here highly resolve that these dead shall not have died in vain--that this nation, under God, shall have a new birth of freedom--and that government of the people, by the people, for the people, shall not perish from the earth."

Lincoln won re-election in 1864, as Union military triumphs heralded an end to the war. In his planning for peace, the President was flexible and generous, encouraging Southerners to lay down their arms and join speedily in reunion.

The spirit that guided him was clearly that of his Second Inaugural Address, now inscribed on one wall of the Lincoln Memorial in Washington, D. C.: "With malice toward none; with charity for all; with firmness in the right, as God gives us to see the right, let us strive on to finish the work we are in; to bind up the nation's wounds.... "

On Good Friday, April 14, 1865, Lincoln was assassinated at Ford's Theatre in Washington by John Wilkes Booth, an actor, who somehow thought he was helping the South. The opposite was the result, for with Lincoln's death, the possibility of peace with magnanimity died.

"I appeal to you again to constantly bear in mind that with you, and not with politicians, not with Presidents, not with office-seekers, but with you, is the question, "Shall the Union and shall the liberties of this country be preserved to the latest generation?"
--From the February 11, 1861 Speech to Gov. Morton in Indianapolis

MOKSHAGUNDAM VISVESVARAYA

The great engineer of india M.VISVESVARAYA
Born: September 15, 1860
Died: April 14, 1962
Achievements: Architect of Krishnarajasagar Dam; devised steel doors to stop the wasteful flow of water in dams; honored with Bharat Ratna.

Sir Mokshagundam Visvesvaraya was an eminent engineer and statesman and played a key role in building of modern India.

Sir M. Visvesvaraya was born on September 15, 1860 in Muddenahalli village in the Kolar district of the erstwhile princely state of Mysore (present day Karnataka). His father Srinivasa Sastry was a Sanskrit scholar and Ayurvedic practitioner. His mother Venkachamma was a religious lady. He lost his father when he was only 15 years old.

Visvesvaraya completed his early education in Chikkaballapur and then went to Bangalore for higher education. He cleared his B.A. Examination in 1881. He got some assistance from the Government of Mysore and joined the Science College in Poona to study Engineering. In 1883 he ranked first in the L.C.E. and the F.C.E. Examinations (equivalent to B.E. Examination of today).

When Sir M. Visvesvaraya cleared his engineering, Government of Bombay offered him a job and appointed him Assistant Engineer at Nasik. As an engineer, he achieved some marvelous feats. He planned a way of supplying water from the river Sindhu to a town called Sukkur. He devised a new irrigation system called the Block System. He devised steel doors to stop the wasteful flow of water in dams. He was the architect of the Krishnaraja Sagara dam in Mysore. The list is endless.

Sir M. Visvesvaraya lead a very simple life. He was a strict vegetarian and a teetotaler. He was known for his honesty and integrity. In 1912, Maharaja of Mysore appointed Visvesvaraya as his Dewan. Before accepting the position of Dewan of Mysore, he invited all his relatives for dinner. He told them very clearly that he would accept the prestigious office on the condition that none of them would approach him for favours. As Dewan of Mysore, he worked tirelessly for educational and industrial development of the state. When he was the Dewan many new industries came up. The Sandal Oil Factory, the Soap Factory, the Metals Factory, the Chrome Tanning Factory , were some of them. Of the many factories he started the most important is the Bhadravati Iron and Steel Works.

Sir M. Visvesvaraya voluntarily retired as Dewan of Mysore in 1918. He worked actively even after his retirement. Sir M. Visvesvaraya was honored with Bharat Ratna in 1955 for his invaluable contribution to the nation. When he reached the age of 100, the Government of India brought out a stamp in his honor. Sir Visvesvaraya passed away on April 14, 1962 at the age of 101.
