Gordon Jackson Rees (8 December 1918 – 19 January 2001) was a British anesthesiologist, recognized as a pioneer in pediatric anesthesia.
During World War II Rees served in the medical branch of the Royal Air Force, and was stationed in Freetown, Sierra Leone from 1943 to 1945.
Rees introduced several practices now standard in managing anesthesia in young patients, including premedication, endotracheal intubation, and muscle relaxants.
The Jackson Rees Department of Anesthesia at the Royal Liverpool Children's Hospital is named in his honor.
However, he is sometimes referred to as "Jackson Rees", or the hyphenated "Jackson-Rees", in contexts that generally use surnames (such as the medical equipment named for him).
