BiographyJoan Maie Freeman was born in Perth on 7 January 1918. Her family moved to Sydney in 1922 and she attended the Sydney Church of England Girls Grammar School. While still a girl, she took evening classes at Sydney Technical College. The school hid her attendance from inspectors, as they thought a girl in the class would reflect negatively on the college.[1] She completed her Intermediate Certificate Examination and earned a place at the University of Sydney in 1936. Freeman studied mathematics, chemistry, physics and zoology, and was often the only woman, indeed the school stipulated that a seat had to be left vacant between women and men in a lecture hall).[1] She received her BSc in 1940 and was awarded a Commonwealth Research Scholarship to continue her MSc. CareerFreeman took a position at the Radiophysics Laboratory of the Council for Scientific and Industrial Research as a research officer in June 1941. She researched radar during World War II. After the war ended, Freeman engaged in research on the behaviour of low-pressure gas discharges at microwave frequencies. The Council for Scientific and Industrial Research then awarded her a Senior Studentship that allowed her to read for her PhD at the University of Cambridge in England. She attended Newnham College and later studied short-range alpha particles with Alex Baxter, working on the HT1 accelerator.[2] In 1951 Freeman became Senior Scientific Officer at the Harwell Tandem Accelerator Group. She later led the group and received the Rutherford Medal and Prize in 1976 with Roger Blin-Stoyle, for their research of the beta-radioactivity of complex nuclei. She was the first woman to win the Rutherford Medal.[1] She received an honorary doctorate from Sydney University and fellowships from the Institute of Physics and the American Physical Society.[2] She retired in 1978.[3] Freeman wrote the 1991 book A Passion for Physics. Freeman married John Jelley in 1958. She died in Oxford on 18 March 1998.[2] References1. ^1 2 {{Cite book|title=International Women In Science: A Biographical Dictionary to 1950|last=Haines|first=Catharine|publisher=ABC-Clio|year=2001|isbn=|location=|pages=102|via=}} {{Authority control}}{{DEFAULTSORT:Freeman, Joan Maie}}2. ^1 2 {{cite news|url=https://www.independent.co.uk/news/obituaries/obituary-joan-freeman-1152660.html|title=Obituary: Joan Freeman|date=22 October 2011|work=The Independent|last1=Hetzel|first1=Phyllis}} 3. ^{{cite news|title=Honorary Awards: Dr Joan Maie Freeman|url=http://sydney.edu.au/arms/archives/history/HonFreemanJM.shtml|work=The University of Sydney News|date=8 June 1993}} 11 : Australian physicists|1918 births|1998 deaths|Women physicists|Australian women scientists|Fellows of the American Physical Society|Fellows of the Institute of Physics|University of Sydney alumni|Alumni of Newnham College, Cambridge|20th-century physicists|20th-century women scientists |
