Lynn Margulis was an eminent American biologist. Her serial endosymbiotic theory of eukaryotic cell development overturned the modern concept of how life originated on the earth. She also made vital contributions to Gaia theory, which deals with the relation of living organisms to their inorganic surroundings. Born in Chicago, Illinois in 1938, Lynn Margulis earned […]
Luigi Galvani was an Italian physician and physicist. One of the early pioneers of bioelectricity, he is known for his extraordinary work on the nature and effects of electricity in an animal tissue, which later led to the invention of the voltaic pile. Born at Bologna, Italy, on September 9, 1737, Luigi Galvani, like his
Ludwig Boltzmann was an Austrian physicist whose efforts radically changed several branches of physics. He is mostly noted for his role in the development of statistical mechanics and the statistical explanation of the second law of thermodynamics.Born in Vienna on February 20, 1844, Ludwig Boltzmann’s father was a tax official. He earned his PhD degree
Lucretius was a Roman poet and philosopher who wrote “De rerum natura” (On the Nature of Things), an epic poem widely regarded as one of the most influential works in history of literature, philosophy and science. In addition to his doctrinal and scientific impact, Lucretius extorted a profounded influence on countless later philosophers and scientists.
If one were to choose among the greatest supporters of humanity, Louis Pasteur would certainly rank at the top. Louis Pasteur was a world-renowned French chemist and biologist born on December 27, 1822 in the town of Dole in Eastern France into the family of a poor tanner. Pasteur’s work gave birth to many branches
Louis de Broglie was an eminent French physicist. He gained worldwide acclaim for his groundbreaking work on quantum theory. In his 1924 thesis, he discovered the wave nature of electrons and suggested that all matter have wave properties. He won the 1929 Nobel Prize for Physics.

Lise Meitner was an Austrian-born, later Swedish, physicist who shared the Enrico Fermi Award in 1966, with fellow chemists Otto Hahn and Fritz Strassmann, for their collaborative work on the discovery of uranium fission. She remains one of the most important figures in the fields of radioactivity and nuclear physics. The name of the chemical
Linus Pauling was an American theoretical physical chemist and activist. He remains one of the greatest chemists ever, and the only person in history to be awarded two unshared Nobel Prizes; in 1954 for studying the nature of the chemical bond, and in 1962 for his efforts regarding the prohibition of nuclear testing. His contributions
Leonhard Euler was an eminent Swiss mathematician and physicist, who is widely credited to be one of the founders of pure mathematics. He made significant contributions to modern analytic geometry and trigonometry. Euler’s critical and formative work revolutionized the fields of calculus, geometry and number theory. Leonhard Euler’s father wished to see his son as
More commonly known as the greatest artist in the history of mankind, Leonardo da Vinci was also a magnificent philosopher and scientist. The most influential figure in the Italian Renaissance, Leonardo is widely considered to be an inventive multi-genius.

Leland C. Clark was born in 1918 in Rochester, New York. Known as the “Father of Biosensors,” Dr. Clark invented the first device to determine rapidly the amount of glucose in blood. His sensor concept permits millions of diabetics to monitor their own blood-sugar levels. He is most well known as the inventor of the
The American inventor and electrical engineer, Lee De Forest is credited for inventing the Audion, a vacuum tube that takes moderately weak electrical signals and amplifies them. The device helped AT&T establish coast-to-coast phone service, and it was also used in everything from radios to televisions to the first computers. Lee De Forest was born
“Every man gets a narrower and narrower field of knowledge in which he must be an expert in order to compete with other people. The specialist knows more and more about less and less and finally knows everything about nothing.”“Truth in science can be defined as the working hypothesis best suited to open the way
American scientist, Katharine Burr Blodgett is known for numerous important contributions to the field of industrial chemistry. She is mainly acknowledged for her invention of the colour gauge and non-reflecting or “invisible” glass. Born in Schenectady, New York on January 10, 1898, Katharine or Katie (her nickname) was the second child of Katharine Burr and
Karl Landsteiner, was an Austrian-born American immunologist, physician and pathologist.
