Jane Harriett Walker CH (24 October 1859 – 7 November 1938) was an English medical doctor who first implemented the open-air method of treating tuberculosis in England.

Determined to become a doctor, she studied at the London School of Medicine for Women in 1880 and qualified as a Licentiate of the Royal College of Physicians of Ireland in 1884.

Impressed, Walker introduced the method into the UK, at a time when many doctors favoured keeping tubercular patients in a warm stuffy environment.

[1] In July 1892, she opened a small sanatorium at a cottage in Downham Market in Norfolk, with six beds, using Walther's method of fresh air and good nutrition.

She died from a coronary thrombosis at her home on Harley Street and was buried in at Wiston, Suffolk.
