Marion Bidder (née Greenwood) (26 August 1862 – 25 September 1932) was an English physiologist and one of the first women to do independent research in Cambridge. For nearly a decade, she was in charge of the Balfour Laboratory in Cambridge and in 1895 she was the first woman to speak about a paper she had written at a Royal Society meeting.

Early life and education

She attended to Bradford Girls' Grammar School and won a scholarship to attend Girton College when she was 17 years old. She graduated with honours in natural sciences. She was the first winner of the Gamble Prize in 1888 for her dissertation.

While doing research at Newnham College, she wrote papers on the gastric glands of pigs, effects of nicotine on invertebrates, and the physiology of protozoa. These papers appeared in the Journal of Physiology.

Career
Starting in 1888, she acted as both a lecturer and director of studies in biology as well as a tutor for female physiology students at Newnham College. Greenwood lead the Balfour Laboratory from 1890. When she married marine biologist George Parker Bidder and gave up the position 11 years later in 1899, it took four people to replace her.

After marrying, Bidder continued to publish works, however they were on the subject of domestic economy. In 1901, Domestic Economy in Theory and Practice was published, to which Bidder contributed on the theoretical and scientific aspects of the subject.
