Jean Maud Bullen

Jean Maud Bullen (1918–2002) was a New Zealand-born geophysicist regarded as one of Australasia's first women pioneers in geoscience.

She was the sister of Keith Edward Bullen.

Career
Bullen was a scholarship winner for the Junior New Zealand Test.

She worked first as a secondary school teacher, and during WW2, she worked for the geological Survey of New Zealand researching groundwater information of New Zealand using magnetometers. She was then a foundation member of the Geophysics Division of the geological Survey of New Zealand.

Until she retired, Bullen worked for the Ionosphere Section of the Department of Scientific and Industrial Research in Christchurch, New Zealand. She spent considerable time preparing instrumentation for upper atmosphere observations, but she never visited the Scott Base.
