Marcus Laurence Elwin Oliphant 1901–2000

Abstract

With the death of Professor Sir Mark Oliphant, the first President of the Australian Academy of Science, Australia lost one of its most distinguished scientists. A tall, handsome man with a shock of white hair and a distinctive voice and laugh, he was well informed on a wide range of scientific matters and expressed firm views on their social consequences. He enjoyed wide respect throughout the nation as a great Australian, his influence spreading far beyond the discipline of physics, to which he made seminal contributions both through his own research and his leadership. The Academy will remember and honour him for his leading role in its establishment, and for his continuing association with it until the last years of his long life.

Oliphant's outstanding international reputation was based on his pioneering discoveries in nuclear physics in Cambridge in the 1930s and his remarkable contributions to wartime radar research and to the development of the atomic bomb. In 1950, after an absence of 23 years, Oliphant returned to Australia, where he founded the Research School of Physical Sciences at the Australian National University and pioneered the creation in Canberra of a national university dedicated to the conduct of research at the highest international level.

To the layman, Mark Oliphant was well known for his often outspoken comments on those matters about which he felt so strongly: social justice, peace, atomic warfare, the environment, academic freedom and autonomy, to name a few. The scientific community will remember him as a physicist for his pioneering experiments with Ernest Rutherford during momentous years that saw the birth of nuclear physics, as a physicist/engineer for his ingenuity and determination as one of the pioneers of high-energy particle accelerators, and as a science administrator and public advocate for science.
