Philip Hauge Abelson passed away on
Aug. 1 at the age of 91. Although some of his early work in physics is most
often recognized, when forced to choose, he considered himself a geologist.
From the age of 30, Abelson never was satisfied working one job in one field.
He was an interdisciplinary researcher, director, president, editor and writer
and avid walker and gardener just to fill out the day.

An eclectic scientist and passionate scientific optimist, Abelson was concerned and involved with encouraging scientists and interdisciplinary science and with making science work for society. He fostered these interests and goals while serving as director of the Naval Research Laboratory in Philadelphia in 1944, the Geophysical Laboratory from 1953 to 1971 and the Carnegie Institution of Washington from 1971 until 1978, as well as president of the American Geophysical Union. From 1962 until 1983, he also was the editor of Science. He continued to serve on the Science editorial board, and was an adviser to other boards interfacing between science and society.
After earning degrees at Washington State University in chemistry and physics, Abelson conducted graduate work in nuclear physics at the University of California, Berkeley. Continuing a collaboration that began there, Abelson and Edwin McMillan created the first artificial element, neptunium, and had tantalizing hints of plutonium. Working independently, he developed an approach that was used in part to produce the material for the first atomic bomb. He then helped conceive and initiate the nuclear submarine program.
His time at the Geophysical Laboratory, first in 1939 and then again in 1946, fostered his work on biology and geology, and the connections between these and other fields. While at the lab, Abelson began prescient studies of E. coli (writing a book that presaged the microbes significance in microbiology) and finding and exploring the significance of amino acids in fossils (presaging the field of biogeochemistry). He also helped foster the careers of scientists from around the world by inviting them to work at Carnegie.
A survey of Abelsons many editorials at Science reveals a deep concern for the connection between science and social good, for pushing scientists, their societies, and governments to work better, as well as relishing in scientific advances.
By the time I met Thomas Gold in 1991,
he had already been retired for 10 years from the directorship of Cornell Universitys
Center for Radio-Physics and Space Research. It was in his home just weeks after
his golden retriever had given birth to eight adorable puppies. During this
first meeting, his attention leaped from the puppies to the stream of faxes
that were literally rolling across his office to an array of jars with black
gunk that he said contained methane from the mantle. It was the latter that
brought me to his home, and it was because of this topic that many geologists
know of Gold, who died on June 22 at age 84. But before elaborating on his thoughts
about primeval methane and his hypothesis of a deep, hot biosphere,
it is of interest to quickly review his career.

Born in Austria in 1920, Gold studied at Trinity College in Cambridge, England, before he was placed in an internment camp for nearly two years. By nature, he was a confident maverick, and this incident must only have strengthened his intolerance for blind thinking and witless authorities. Undaunted, Gold continued to study mathematics and befriended Hermann Bondi, who, along with Fred Hoyle, would become an important colleague in his research in cosmology.
Immediately after his release from the camp, Gold worked for the British Admiralty and lectured in advanced physics at Cambridge University. In 1956, he became the chair of Harvards Astronomy Department and then moved on to Cornell. A recipient of many awards, he was a member of the National Academy of Sciences, the American Philosophical Society and, for seven years, the Presidents Space Science Panel.
Controversy was part of Golds nature, with his many theories always at the edge of believability. He nimbly jumped from astrophysics to space engineering to geology from problems of radar ground clutter and the workings of the inner ear to neutron stars and the magnetosphere (which he coined), to name a few.
The Guardian referred to Gold as an extroverted propagandist. He passionately believed in his ideas and wanted all of humanity to benefit from them. That brings me back to the subject of my 1991 meeting with him about the mantle.
When it came to his hypothesis that fossil fuels originate inorganically from deep in Earth, many scientists reacted with disdain. Frankly, if Golds idea of mantle gas is correct, wont we all be better off? If not, what have we lost? Science needs more Tommy Golds.
