Janet Welch Mackie MBE (March 2, 1894 – November 24, 1959) was an English doctor who worked mainly in East Africa and the United States.

Her work, research and published material helped in establishing modern healthcare and nursing practices in the developing world.

[citation needed] Welch entered the Church of Scotland Missionary Service on September 16, 1926 and by November of that year she was registered as a medical practitioner in Nairobi, Kenya.

[8] By 1928 Welch had moved south to Nyasaland (modern day Malawi), where she joined the staff of the Church of Scotland Hospital in Blantyre.

[11] In October 1938, Welch sailed back to England, left the missionary service and embarked on the next stage of her career.

[13] Welch worked in New York for several months, living at the address of her future husband Thomas T. Mackie on Park Avenue before sailing in June 1940 to Puerto Rico.

[citation needed] In 1941 Welch published a booklet, Nursing Education related to the Cultural Background in East and Southeast African Colonies.

[citation needed] Welch returned to England briefly during late 1941, leaving again on February 20, 1942 on board the SS Aircrest in an Atlantic convoy.

[citation needed] Reunited following the end of the war, Janet and Thomas were offered the opportunity to head up a new department at the Bowman Gray School of Medicine in Winston Salem, North Carolina.

She is recorded as having been a US Public Health Service adviser in Thailand (1954) as well as with native American communities in the southwestern United States, Alaska and Hawaii.

She was buried at the Rock Creek Cemetery in Washington, D.C. She met her future husband Thomas Mackie at the London School of Medicine in 1930/31 when both were carrying out post graduate studies there.
