Jean Mary Henderson (18 December 1899 – 1 April 1997) was a British barrister and Liberal Party politician.

Henderson then went up to Bedford College, London University, where she graduated in modern languages (French, German and Russian).

On leaving university, Henderson first went to work in journalism, joining the foreign desk of the Westminster Gazette.

She also edited a magazine for the anti-war Women's International League and acted as part-time secretary to David Low the famous cartoonist.

Under the regulations of the time women received 7 shillings a week less than male civilians for the same injuries even though they faced equal danger in their homes, as targets in industry or working in civil defence.

[6] In 1950 Henderson switched her attentions to Lincoln,[2] this time with even less success, taking less than 9% of the vote and again losing her deposit.

[7] She did not contest a seat at the 1951 general election but she returned to the fray, first by becoming prospective parliamentary candidate for Watford in 1953 but then changing constituencies to fight at Luton in 1955.

[10] In 1968, Henderson became one of the first directors of the New Hampstead Garden Suburb Trust, which was granted powers to refuse proposed developments in the area which they believed were harmful to its character.

[11][12] A substantial collection of Jean Henderson's papers covering her political work during the years 1916–1993, have been deposited in the LSE Library.
