Ruby Payne-Scott
Encyclopedia
Ruby Violet Payne-Scott (28 May 1912 – 25 May 1981) was an Australian pioneer in radiophysics
Radiophysics
Radiophysics is a branch of physics focused on the theoretical and experimental study of certain kinds of radiation: its emission, propagation, and interaction with the medium.The term is used in the following major meanings:...

 and radio astronomy
Radio astronomy
Radio astronomy is a subfield of astronomy that studies celestial objects at radio frequencies. The initial detection of radio waves from an astronomical object was made in the 1930s, when Karl Jansky observed radiation coming from the Milky Way. Subsequent observations have identified a number of...

Career

One of the more outstanding physicists that Australia has ever produced and one of the first people in the world to consider the possibility of radio astronomy

, and thereby responsible for what is now a fundamental part of the modern lexicon of science, she was often the only woman in her classes at the University of Sydney.

Her career arguably reached its zenith while working for the Australian government's Commonwealth Scientific and Industrial Research Organisation (then called CSIR, now known as CSIRO) at Dover Heights

 in Sydney, Australia. Some of her fundamental contributions to solar radio astronomy came at the end of this period. She is the discoverer of Type I and Type III bursts and participated in the recognition of Type II and IV bursts. Payne-Scott played a major role in the first-ever radio astronomical interferometer observation from 26 January 1946, when the sea-cliff interferometer was used to determine the position and angular size of a solar burst. This observation occurred at either Dover Heights (ex Army shore defence radar) or at Collaroy (ex Royal Australian Air Force radar).

Radar
Radar is an object-detection system which uses radio waves to determine the range, altitude, direction, or speed of objects. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. The radar dish or antenna transmits pulses of radio...

 was interested in Payne-Scott and had a substantial file on her activities, with some distortions.

Bill Hall and Ruby Payne-Scott secretly married in 1944; at this time, the Commonwealth government had legislated that a married woman could not hold a permanent position within the public service. She continued to work for CSIR while secretly married until the regulations of the new CSIRO in 1949 raised the issue of her marriage. The following year, her treatment by CSIRO resulted in hostile written exchanges with Sir Ian Clunies Ross

 (Chairman of CSIRO) about the status of married women in the work place. She lost her permanent position in CSIRO. However, her salary was maintained at a level comparable to that of her male colleagues. In 1951, she resigned a few months before her son Peter was born; there was no maternity leave at this time.

She changed her name to Ruby Hall only after she left CSIRO. Bill and Ruby Hall had two children: Peter Gavin Hall, an internationally renowned mathematician working in theoretical statistics and probability theory, and Fiona Margaret Hall, one of Australia's more prominent artists, whose career is described by Julie Ewington in her 2005 book Fiona Hall.

Ruby Payne-Scott died in Sydney, New South Wales, 25 May 1981. She suffered from Alzheimer's disease
