Georges Jean Franz Köhler was a German immunologist who shared (with César Milstein and Niels K. Jerne) the 1984 Nobel Prize for Physiology or Medicine for his work in developing the technique for producing monoclonal antibodies - pure, uniform, and highly sensitive protein molecules used in diagnosing and combating a number of diseases. These antibodies, and the subsequent developments based their work, revolutionized the diagnosis and treatment of many immunologic diseases, including some forms of cancer and AIDS. In 1975, he and Milstein published in Nature the results of their work leading to the production of monoclonal antibodies “Continuous cultures of fused cells secreting antibody of predefined specificity.” Milstein's and Köhler's method of producing monoclonal antibodies involves fusing an antibody-producing cell - which can recognize an invading organism - with a tumor cell, which lives and reproduces indefinitely. Their discoveries are being used in research on mild illnesses and diseases such as cancer and AIDS.

American geneticist who demonstrated the colinearity of gene and protein structures. In the 1960s, Yanofsky began work on the structure of proteins and genes responsible for tryptophan biosynthesis. He used the expression and regulation of these proteins as tools to dissect the inner workings of the cell's genetic apparatus. This work on the nature of mutations that prevent tryptophan biosynthesis produced some of his most significant discoveries. His remarkable exploitation of the E. coli tryptophan operon to work out the biochemical pathway of the synthesis of an amino acid and to elucidate fundamental aspects of transcription and translation, such as missense suppression and polarity, are historic achievements.

English entomologist who pioneered in the study of insect physiology; he was particularly respected for his research into the role of hormones in insect growth, metamorphosis, and reproduction and for his insights into simple mechanisms, such as how insects walk upside down. His investigations of the living insect body and its tissues and organs revealed much about the dynamic complexity of individual insects and their interactions with the environment. An important contribution was his recognition that insects could be used - instead of mice or other laboratory animals - for the fundamental investigation of animal physiology and function. His Insect Physiology (1934) is often considered the foundation for this branch of entomology.

Charles Leonard Woolley was an English archaeologist whose excavation (1922-34) of the ancient Sumerian city of Ur (in modern Iraq), the royal burial site of many Mesopotamian royalties, greatly advanced knowledge of ancient Mesopotamian civilization, enabling scholars to trace the history of the city from its final days during the 4th century BC back to its prehistoric beginnings (c. 4000 BC). His finds revealed much about everyday life, art, architecture, literature, government, and religion in this "cradle of civilization. " In royal tombs dating from about 2700 BC, he uncovered the practice of the sacrificial burial of a deceased king's personal retinue. He discovered tombs of great material wealth, gold and silver jewelry, large paintings of ancient Mesopotamian culture at its zenith, and other furnishings. The most extravagant tomb of Queen Pu-Abi was untouched by the hands of looters through the millennia, with many well-preserved items, including a cylindrical seal bearing her name in Sumerian. His widely read Ur of the Chaldees: A record of seven years of excavation (1929), described his findings in a manner both informative to specialists and accessible by lay-persons.

English physiologist whose prolific contributions to a modern understanding of body functions include Starling’s hypothesis (in which he described the forces that propel fluids through blood vessels) and his discovery of how hormones and nerves control digestion. He coined the term hormone for the body’s chemical messengers from the endocrine glands (1905). His “law of the heart” stated the strength of the heart contraction is proportional to the stretching of the heart muscle. He discovered the functional significance of serum proteins. In 1902 along with William Bayliss he demonstrated that secretin stimulates pancreatic secretion. In 1924, along with Ernest B. Verney, he demonstrated the reabsorption of water by the tubules of the kidney.

British geophysicist and mathematician who discovered a major type of earthquake wave that was subsequently named for him. Love assumed that the Earth consists of concentric layers that differ in density and postulated the occurrence of a seismic wave confined to the surface layer (crust) of the Earth which propagated between the crust and underlying mantle. His prediction was confirmed by recordings of the behaviour of waves in the surface layer of the Earth. He proposed a method, based on measurements of Love waves, to measure the thickness of the Earth's crust. In addition to his work on geophysical theory, Love studied elasticity and wrote A Treatise on the Mathematical Theory of Elasticity, 2 vol. (1892-93).

German-American mathematician and educator, a pioneer in the development of algebra theory. He worked with Weyl on several projects including a famous joint paper on spinors (published in 1935 in the American Journal of Mathematics). This work provided a background for Paul Dirac's theory of the spinning electron within the framework of quantum mechanics. With Nesbitt, Brauer introduced the theory of blocks (1937). Brauer used this to obtain results on finite groups, particularly finite simple groups, and the theory of blocks would play a big part in much of Brauer's later work. Starting with his group-theoretical characterisation of the simple groups (1951), he spent the rest of his life formulating a method to classify all finite simple groups.

Jean-Baptiste Perrin was a French physicist who, in his studies of the Brownian motion of minute particles suspended in liquids, verified Albert Einstein's explanation of this phenomenon and thereby confirmed the atomic nature of matter. Using a gamboge emulsion, Perrin was able to determine by a new method, one of the most important physical constants, Avogadro's number (the number of molecules of a substance in so many grams as indicated by the molecular weight, for example, the number of molecules in two grams of hydrogen). The value obtained corresponded, within the limits of error, to that given by the kinetic theory of gases. For this achievement he was honoured with the Nobel Prize for Physics in 1926.

Canadian nuclear physicist who was probably the first to observe the recoil of the atomic nucleus as nuclear particles were emitted during radioactive decay. During the years 1901-05, she contributed much to the new science of radioactivity. Working with Ernest Rutherford, she measured the rate at which radium released radon (and other gases) into the air. They demonstrated that the diffusion of the emanations of radium both behaved like a a gas, and that this gas had a high (over 100) molecular weight. Rutherford credited her work identifying the release of radon as crucial to developing his theory of the transmutation of one element into another. She died at the age of 56, from leukemia or a like disease related to radiation exposure.

Surveyor 3 carried a survey television camera, soil mechanics experiments, and devices to measure temperature and radar reflectivity as on the earlier missions. Its mass was1026 kg at launch and 296 kg upon landing.«
In 1964, Geraldine (“Jerrie”) Mock landed in Columbus, Ohio, becoming the first woman to complete a solo airplane flight around the world. She was a Columbus housewife with less than 800 hours logged in 7-1/2 years of flying experience, and had received her instrument rating less than a month before taking off from Columbus, on 19 Mar 1964, in a single-engine Cessna Model 180 aircraft on her 23,206-mile solo air voyage. The trip lasted 29-1/2 days with 21 stopovers. The insignia on the aircraft was “Spirit of Columbus,” but it was nick-named “Three-Eight Charlie.” She was born in Newark, Ohio, and had studied Aeronautical Engineering at Ohio State University. Though not without some problems, the ultimate success of her solo flight also reflects the reliability of small aircraft of the era.«
In 1930, the discovery of a new rubber-like compound was recorded by Dr. Arnold M. Collins in his laboratory notebook. He had noticed that a mixture that had stood from some weeks before, had solidified “to white, somewhat rubber-like masses,” from polymerization of monovinylacetylene mixed with concentrated HCl. He theorized the new compound was 2-chloro-1,3-butadiene. His research group at the Du Pont Company, over the next several weeks, but only gradually, recognized its potential as the first synthetic rubber. Wallace Carothers named it chloroprene. It was announced as DuPrene on 2 Nov 1931. After more development, it was sold as a material useful for products impervious to oil, for electrical wire insulation and as a coating compound. From 1936, it is known as Neoprene.«
In 1906, San Francisco was hit by a disastrous earthquake.
In 1861, the first oil well fire occurred at the Little and Merrick well at Oil Creek, near Rouseville, Pennsylvania. It ignited shortly after gushing, burned for three days, and resulted in 19 deaths.
In 1844, the first U.S. patent for a cylinder and flatbed combination printing press was issued to Robert Hoe.
In 1810, the first U.S. patent for pineapple cheese was issued to L.M. Norton of Troy, Pennsylvania.
