Malcolm I. Raff (1940 - 2010)

In his seventy years, Malcolm Raff never did figure out exactly what he wanted to be when he grew up. The only son of lawyer Henry Raff and music teacher Ruth Raff (nee Marshak), Mal’s interests vacillated between the analytical and the artistic. Early skill as a pianist and trombone player competed for his youthful attention with amateur radio and astronomy, leading him to pursue a liberal arts education at Gettysburg College in Pennsylvania, from which institution he earned BS degrees in math and physics in 1961.

Thomas J. Ahrens (1936 - 2010)

Thomas J. Ahrens, a leader in the use of shock waves to study planetary interiors and impact phenomena, died at his home in Pasadena, California on November 24, 2010, at the age of 74. He was the California Institute of Technology’s Fletcher Jones Professor of Geophysics, formally emeritus since 2005 but professionally active to the end.

Brian G. Marsden (1937 - 2010)

Brian Geoffrey Marsden was born on 1937 August 5 in Cambridge, England. His father, Thomas, was the senior mathematics teacher at a local high school.  It was his mother, Eileen (nee West), however, who introduced him to the study of astronomy, when he returned home on the Thursday during his first week in primary school in 1942 and found her sitting in the back yard watching an eclipse of the sun.  Using now frowned-upon candle-smoked glass, they sat watching the changing bite out of the sun.
