    (Purcell, Edward Mills (1912–1997





    American physicist at Harvard who shared with Felix Bloch (at Stanford) the 1952 Nobel Prize in Physics for his independent work on the nuclear magnetic moment, discovering nuclear magnetic resonance (NMR) in solids. Purcell was also the codiscoverer, with Harold I. Ewen, in 1951, of the 21- centimeter line of hydrogen.

    In a lecture delivered at Brookhaven National Laboratory, in 1960, Purcell attacked the notion that intersteller travel would ever be possible, arguing that radio signals were probably the best way of establishing contact with other intelligent races. A similar discouraging outlook for flight between the stars was expressed by Pierce and Von Hoerner

          (Barnard, Edward Emerson (1857–1923

    (Barnard, Edward Emerson (1857–1923







    One of the greatest observational astronomers of his time, and discoverer of Jupiter's moon Amalthea and the nearby star that now bears his name - Barnard's star -. Born into poverty in Nashville, Tennessee, Barnard began work in a photographic studio when he was only nine. He became a brilliant amateur astronomer, discovering 10 comets before the age of 30.

    In 1887, Barnard joined the staff of Lick Observatory and used the new 36-inch Lick refractor to discover Amalthea and the first comet to be found by photography, both in 1892. In 1895 he moved to the University of Chicago's not-yet-completed Yerkes Observatory and helped test the great 40-inch refractor following its installation

    Barnard spent 28 years as an astronomer at Yerkes using the giant refractor as well as the 10-inch Bruce wide-field telescope, built specially for him, to measure star positions and to pioneer wide-field photography for studying the structure of the Milky Way. He discovered the star, subsequently named after him, with the largest known proper motion, and numerous dark clouds and globules

    (Morgan, William Wilson (1906–1994

    American astronomer who, with Philip Keenan (1908–2000) and Edith Kellman (1911–2007), introduced stellar luminosity classes and developed the Morgan-Keenan classification of stellar spectra. With Donald Osterbrock and Stewart Sharpless he demonstrated the existence of spiral arms in the Galaxy using precise distances of O and B stars obtained from spectral classifications. Morgan helped originate the UBV system of magnitudes and colors, and, with Nicholas Mayall, developed a spectral classification system for giant galaxies. After three years of undergraduate study at Washington and Lee University, Morgan joined the staff of the Yerkes Observatory, where he spent his entire career, including three years as director. While at Yerkes he earned bachelor's and doctoral degrees at the University of Chicago. Eschewing theory, his research focused on morphology – the classification of objects by their form and structure.

    Lightbulb John Flamsteed

    John Flamsteed




    John Flamsteed, (born Aug. 19, 1646, Denby, near Derby, Derbyshire, Eng.—died Dec. 31, 1719, Greenwich, London), founder of the Greenwich Observatory, and the first astronomer royal of England.

    Poor health forced Flamsteed to leave school in 1662. He studied astronomy on his own and later (1670–74) continued his education at the University of Cambridge. In 1677 he became a member of the Royal Society. Ordained a clergyman in 1675, Flamsteed in 1684 received the income of the living of Burstow, Surrey. His report to the Royal Society on the need for a new observatory resulted in the founding (1675) of the Royal Greenwich Observatory, of which he was the first director (and hence astronomer royal). He found that he himself had to supply all the instruments at Greenwich, apart from a few gifts; he was forced to take private pupils to augment his income. A small inheritance from his father, who died in 1688, provided the means to construct a mural arc, a wall-mounted instrument for measuring the altitudes of stars as they passed the meridian.

    The latter part of Flamsteed’s life passed in controversy over the publication of his excellent stellar observations. He struggled to withhold them until completed, but they were urgently needed by Isaac Newton and Edmond Halley, among others. Newton, through the Royal Society, led the movement for their immediate publication. In 1704 Prince George of Denmark undertook the cost of publication, and, despite the prince’s death in 1708 and Flamsteed’s objections, the incomplete observations were edited by Halley, and 400 copies were printed in 1712. Flamsteed later managed to burn 300 of them. His own star catalog, Historia Coelestis Britannica (1725), listed more stars (3,000) and gave their positions much more accurately than did any other previous work. Some stars, such as 61 Cygni, are still known by their numbers in his system

    Neil Armstrong



    Neil Alden Armstrong (August 5, 1930 – August 25, 2012) was an American astronaut, test pilot, aerospace engineer, university professor and United States Naval Aviator. He was the first person to walk on the Moon. Before becoming an astronaut, Armstrong was a United States Navy officer and had served in the Korean War. After the war, he served as a test pilot at the National Advisory Committee for Aeronautics High-Speed Flight Station, now known as the Dryden Flight Research Center, where he logged over 900 flights. He graduated from Purdue University and completed graduate studies at the University of Southern California.
    A participant in the U.S. Air Force's Man In Space Soonest and X-20 Dyna-Soar human spaceflight programs, Armstrong joined the NASA Astronaut Corps in 1962. His first spaceflight was the NASA Gemini 8 mission in 1966, for which he was the command pilot, becoming one of the first U.S. civilians in space.[not in citation given] On this mission, he performed the first manned docking of two spacecraft with pilot David Scott.
    Armstrong's second and last spaceflight was as mission commander of the Apollo 11 moon landing in July 1969. On this mission, Armstrong and Buzz Aldrin descended to the lunar surface and spent 2½ hours exploring, while Michael Collins remained in orbit in the Command Module. Armstrong was awarded the Presidential Medal of Freedom by President Richard Nixon along with Collins and Aldrin, the Congressional Space Medal of Honor by President Jimmy Carter in 1978, and the Congressional Gold Medal in 2009.
    On August 25, 2012, Armstrong died in Cincinnati, Ohio. at the age of 82 due to complications from blocked coronary arteries.

          Joseph von Fraunhofer

    Joseph von Fraunhofer
    1787-1826




    Born in Straubing, Bavaria, on 6 March 1787. Orphaned at the age of 11, he did an apprenticeship as lens and mirror maker, after which he became employed in a Munich company making scientific instruments. He learned mathematics and became very skilled in applied optics. He is especially known for the discovery of the dark absorption lines known as Fraunhofer lines in the Sun's spectrum, and for making excellent optical glass and achromatic telescope objectives. Fraunhofer worked at the Optical Institute at Benediktbeuern, a secularised Benedictine monastery devoted to glass making. There he discovered how to make the world's finest optical glass and invented incredibly precise methods for measuring dispersion. In 1818 he became the director of the Optical Institute. Due to the fine optical instruments he had developed, Bavaria overtook England as the centre of the optics industry. Even the likes of Michael Faraday were unable to produce glass that could rival Fraunhofer's. In 1821 Fraunhofer built the first diffraction grating, comprised of 260 close parallel wires. Well versed in the mathematical wave theory of light, Fraunhofer used his diffraction grating to actually measure wavelength of specific colors and dark lines in the solar spectrum. He also built and studied reflection gratings. His career eventually earned him an honorary doctorate from the University of Erlangen in 1822. In 1824, he was awarded the order of merit, became a noble, and made an honorary citizen of Munich. Like many glassmakers of his era who were poisoned by heavy metal vapours, Fraunhofer died young, in 1826 at the age of 39. His most valuable glassmaking recipes are thought to have gone to the grave with him

          Friedrich Georg Wilhelm Struve

    Friedrich Georg Wilhelm Struve
    Born: 15-Apr-1793
    Birthplace: Altona, Germany
    Died: 23-Nov-1864
    Location of death: St. Petersburg, Russia
    Cause of death: unspecified



    German-Russian astronomer, the son of Jacob Struve, was born at Altona on the 15th

    of April 1793. In 1808 he entered the university of Dorpat (Yuriev), where he first

    studied philology, but soon turned his attention to astronomy. From 1813 to 1820 he

    was extraordinary professor of astronomy and mathematics at the new university and

    observer at the observatory, becoming in 1820 ordinary professor and director. He

    remained at Dorpat, occupied with researches on double stars and geodesy until 1839,

    when he removed to superintend the construction of the new central observatory at

    Pulkowa near St. Petersburg, afterwards becoming director. Here he continued his

    activity until he was obliged to retire in 1861, owing to failing health. He died at St.

    Petersburg on the 23rd of November 1864.

    Struve's name is best known by his observations of double stars, which he carried on

    for many years. These bodies had first been regularly measured by William Herschel,

    who discovered that many of them formed systems of two stars revolving around their

    common center of gravity. After him John Herschel (and for some time Sir James South)

    had observed them, but their labors were eclipsed by Struve. With the 9.5" refractor

    at Dorpat he discovered a great number of double stars, and published in 1827 a list of

    all the known objects of this kind (Catalogus novus stellarum duplicium). His micrometric

    measurements of 2714 double stars were made from 1824 to 1837, and are contained

    in his principal work, Stellarum duplicium et multiplicium mensurae micrometricae (St.

    Petersburg, 1837). The places of the objects were at the same time determined with

    the Dorpat meridian circle (Stellarum fixarum imprimis duplicium et multiplicium

    positiones mediae, St. Petersburg, 1852). At Pulkowa he redetermined the "constant of

    aberration", but was chiefly occupied in working out the results of former years' work

    and in the completion of the geodetic operations in which he had been engaged during

    the greater part of his life. He had commenced them with a survey of Livonia

    (1816-19), which was followed by the measurement of an arc of meridian of more than

    3.5° in the Baltic provinces of Russia (Beschreibung der Breitengradmessung in den

    Ostseeprovinzen Russlands, 2 vols. 4to, Dorpat, 1831). This work was afterwards

    extended by Struve and General Tener into a measurement of a meridional arc from the

    north coast of Norway to Ismail on the Danube (Arc du méridien de 25° 20' entre le

    Danube et la Mer Glaciale, 2 vols. and 1 vol. plates, 4to, St. Petersburg, 1857-60).
