He is noted for his wide variety of scientific contributions. Harold Jeffreys was born on April 22, 1891, in Durham, England. He graduated from Durham University and then carried out research in chemistry and photography. He won major prizes at the University of Cambridge, from which he graduated in 1917, in mathematics, astronomy, and geophysics. At Cambridge he was a lecturer in mathematics, reader in geophysics, and Plumian professor of astronomy and experimental philosophy from 1946 to his retirement in 1958. In 1940 he married Bertha Swirles, a talented mathematician and a fellow of Girton College, Cambridge. Scientific Contributions Using observations on the earth's bodily tides, Jeffreys, in 1926, gave the first quantitative estimate of the rigidity of the earth's core and established that most of the core is probably molten. He was the senior author of tables produced during 1930-1940, giving the travel times of earthquake waves through the interior of the earth. Since 1940 these tables have been used as the standard in calculating the epicenters and origin times of the world's earthquakes for the International Seismological Summary. Jeffreys also contributed notably to theories of seismic wave propagation, of mutations of the earth's axis, on mountain building, on convection currents inside the earth, on tidal problems, on the figure of the earth and the moon, and a theory on the internal structures of other terrestrial planets.

This photograph was probably taken in October 1935 when Ewing, Crary and Rutherford made the first seismic profiles in the open sea. "Doc" Ewing, as he was called, worked his students hard and himself harder. Just before sailing, he would go below into the vessel's machine shop and turn a lathe all night preparing an instrument, and then go on all day taking observations, with the inevitable result shown in Fig. 1.

Jeffreys was a noted physical scientist who re-established the statistical theory of his time on Bayesian foundations.

    Extractions: U.S. Geological Survey, Reston, Va. Sir Harold Jeffreys is a world authority in theoretical geophysics. He was born in Northumbria (the northeast of England) and educated at Armstrong College (now the University of Newcastle-upon-Tyne) and Cambridge University. He is now a Senior Fellow of St. John's College, Cambridge. He has published over 300 scientific papers and is the author of 7 books, including Theory of Probability and Mathematical Physics (with his wife, Lady Bertha Swirles Jeffreys). Sir Harold has made innumerable theoretical contributions to seismology. Many of these are documented in his book The Earth , which has been published in six editions. His papers have recently been collated by Gordon and Breach (Publishers) into six volumes, Collected Papers of Sir Harold Jeffreys on Geophysics and Other Sciences . Some idea of the breadth of this research can be seen from the individual volume titles: "Theoretical and Observational Seismology," "Observational Seismology," "Gravity," "Dissipation of Energy and Thermal History," "Astronomy and Geophysics," and "Mathematics, Probability and Miscellaneous Other Sciences." Sir Harold has also served as Director of the International Seismological Summary (ISS). Among the honors bestowed upon him by various scientific organizations are Fellow of the Royal Society, Royal and Copley Medals of the Royal Society, Foreign Associate of the U.S. National Academy, Bowie Medalist of the American Geophysical Union, Medalist of the Seismological Society of America, and the Vetlesen Prize.

    Extractions: 2005 Salt Lake City Annual Meeting (October 16–19, 2005) Paper No. 99-8 Presentation Time: 5:15 PM-5:30 PM GALVIN, Cyril , Coastal Engineer, Box 623, Springfield, VA 22150, galvincoastal@juno.com. Scientists know Karl Popper (1902-1994) for his Logic of Scientific Discovery , published first in German (1935, Vienna) and much later in English (1959, London). Geophysicists know Harold Jeffreys (1891-1989) for his Earth , which went through six editions (1924-1976). Chapter V in Popper (1935) deals with simplicity (Einfachheit) in science, Popper developing ideas of Hermann Weyl (1885-1955). Popper later discovered that Wrinch and Jeffreys (1921) anticipated Weyl (1927). In his (1959) footnotes, Popper gives Jeffreys credit for ideas on simplicity. Popper uses deduction idealistically to falsify scientific theories, and Jeffreys uses "common-sense" induction, which is logically untenable in Popper's view, to construct scientific theories. Popper considers the simpler equation to have lower probability, but Jeffreys observes that scientists choose as better the simpler of two equations describing the same phenomenon, even where the more complex equation fits the data better. A simple equation has the dependent variable, a physical quantity, as the left hand side of the equation and a function of n independent variables, also physical quantities, as the right hand side, where n is 0, 1, 2, 3, or 4. Each variable has k dimensions, where k is 0, 1, 2, or 3. These are Bridgman's L, T, M dimensions. Where the dependent variable equals a constant, n equals 0, but that constant has the dimensions of the dependent variable. Where an independent variable is dimensionless, k equals 0.

    Extractions: Born in Northampton in 1903, she was involved in the world of education from her earliest days. Her widowed mother was a primary-school teacher and various aunts were also teachers. She attended Northampton School for Girls and then went up to Girton, in 1921, to read Mathematics, graduating with first class Honours. She became a research student of R.H. Fowler, one of a distinguished company of his students which included several Nobel prizewinners such as P.A.M. Dirac and Subrahmanyan Chandrasekhar. She spent the winter semester of 1927-28 in Gottingen, where she worked under Max Born and Werner Heisenberg and interacted with many of the other leading continental workers in the relatively new field of quantum mechanics; it was an exciting time. By the time she was awarded her PhD in 1929, she was already an Assistant Lecturer in Manchester. This was followed by similar appointments in Bristol and at Imperial College, London, and then in 1933 she returned to Manchester as a Lecturer in Applied Mathematics. Douglas Hartree at Manchester was extremely sorry to lose such a valued colleague when she returned to Cambridge in 1938, to an Official Fellowship and Lectureship in Mathematics at Girton.
