Ruby Violet Payne-Scott, BSc (Phys) MSc DipEd (Syd) (28 May 1912 – 25 May 1981) was an Australian pioneer in radiophysics and radio astronomy, and was one of two Antipodean women pioneers in radio astronomy and radio physics at the end of the second world war, Ruby Payne-Scott the Australian and Elizabeth Alexander the New Zealander. Both women suffered misogyny in their careers, and an unnecessary argument half a century later introduced competitiveness which did not exist at the time. The resolution of in favour of Alexander in no way detracts from the achievements of Ruby Payne-Scott.
