Tor Hagfors (1930 - 2007)

Tor Hagfors, a world leader in the use of radar techniques to observe ionospheres, surfaces and interiors of planetary bodies, died of heart-failure on 17 January 2007, in Puerto Rico, at the age of 76. He was born on 8 December 1930, in Oslo, Norway, and received his education there and in Trondheim, where he graduated with exceptionally good grades with a degree in technical physics from the Norwegian Institute of Technology (NTH) in 1955.

Edward R. Harrison (1919 - 2007)

Cosmologist Edward R. (Ted) Harrison, emeritus Distinguished University Professor of Physics and Astronomy at the University of Massachusetts Amherst, died on 29 January 2007 in his retirement city of Tucson, Arizona, where he was adjunct professor at the Steward Observatory, University of Arizona. The cause of death was colon cancer. He is survived by a sister, brother, and daughter. (A son died in 2000.)

Wayne Carlos Hendrickson (1953 - 2007)

Wayne Carlos Hendrickson was born on born 4 December 1953 in Alhambra, California. He earned a BA/BS in Physics from the University of California at Irvine circa 1975. His PhD in astrophysics was earned in 1984 at the University of Texas at Austin. Hendrickson worked at Raytheon Corporation, for most of the rest of his life, on classified research. He died 8 August 2007.

John J. Hillman (1938 - 2006)

John J. Hillman, a dedicated NASA civil servant, spectroscopist, astrophysicist, planetary scientist, and mentor, died on February 12, 2006 of ocular melanoma at his home in Columbia, Maryland. His professional and personal interests were wide-reaching and varied, and he devoted his career to the advancement of our understanding of the beauty and wonder in the world around us. His love of nature, art, and science made him a true Renaissance man.

E. Dorrit Hoffleit (1907 - 2007)

For Ellen Dorrit Hoffleit, who died on 9 April 2007 in New Haven, Connecticut, shortly after her 100th birthday, World War II, in which she did at least her fair share of the work, was "the war," but she also lived through World War I ("the Great War" until she was well into her 30s), Korea, Vietnam, the first Gulf War, and (we hope) most of Iraq.

Michael William Johnson (1949 - 2007)

Michael W. Johnson was born on 1 September 1949. He received his B.S. (Physics) from the University of San Francisco in 1971, his M.S. (Physics) from the University of Toledo in 1974, and his Ph.D. (Astrophysics) from the University of Pennsylvania in 1981. His doctoral thesis was entitled, "HEAO A-1 Observations of X ray Emitting Clusters of Galaxies," and he was an author of a 1983 catalog of X-ray emitting clusters.

Per E. Maltby (1933 - 2006)

Professor Per Maltby, prominent Norwegian Solar Physicist at the Institute of Theoretical Astrophysics, University of Oslo, Norway, died on 24 May 2006. Lung cancer was diagnosed in February, but he was expected to improve. Until the end of March he came to his office every day, got recent papers off the web, and followed his field closely as he had always done.

Timothy P. McCullough Jr. (1910 - 2004)

Timothy Pendleton McCullough Jr., 93, a retired research physicist who was a pioneer in the measurement of microwave radiation from planetary surfaces, died of cardiac arrest on 19 November 2004, at Inova Fairfax Hospital. He lived in Springfield, VA.

McCullough, who was principally a radio astronomer, published 22 scientific research papers while working in the Atmosphere and Astrophysics Division of NRL, from 1946 until his retirement in 1975.

Thomas Robert Metcalf (1961 - 2007)

The astronomy community lost a good friend when Tom Metcalf was killed in a skiing accident on Saturday, 7 July 2007, in the mountains near Boulder, Colorado. Tom was widely known for prolific work on solar magnetic fields, hard-X-ray imaging of solar flares, and spectral line diagnostics. He was often characterized as "one of the nicest guys in science."

Hugo Schwarz (1953 - 2006)

Hugo Schwarz died in a motorcycle accident on 20 October 2006 near his home in La Serena, Chile. At the time of his death he was a staff astronomer at Cerro Tololo Inter-American Observatory and President of IAU Commission 50 (The Protection of Existing and Potential Observatory Sites).

Gerald Frederick Tape (1915 - 2005)

Gerald Frederick Tape, a distinguished science statesman and administrator, died on November 20, 2005. Jerry, as he was known to all, took on many diverse and important responsibilities throughout his life and dealt with them with quiet authority and grace. This was the hallmark of his life. The Board of Trustees of Associated Universities, Inc., which he served for many years, expressed this in its condolences, writing "Jerry personified integrity, thoroughness and dedication.

James H. Trexler (1918 - 2005)

James H. "Trex" Trexler, Naval Center for Space Technology, a retired scientist and astronomer, with a 50-year career at NRL died of cancer on October 22, 2005, at the age of 87.

Born in Missoula, Montana (May 18, 1918), he grew up in Dallas, Texas, and attended Southern Methodist University (SMU) Engineering School. He combined his interests in astronomy and radio communication and operated the observatory on the SMU campus. Mr. Trexler had a most interesting and rewarding career at NRL, which resulted in notable contributions in scientific and technical developments.
