Alice Gaddum née Behrens (23 April 1885 - 28 June 1952) was Girl Guiding pioneer, becoming the movement's first de facto commissioner in 1914.

[2] She was the movement’s first head of training,[3] oversaw the senior Guides, which would evolve into Rangers[4] and was the first Guider-in-Charge at Foxlease.

Around 1933 they moved to Orielton House on the Pembrokeshire coast[7][8] where Gaddum took a keen interest in supporting the local hospital.

With encouragement from Helen Malcolm, she became the first de facto commissioner for Guides in Manchester, Salford and district,[12][13] "even before that position as such had been invented," the movement's still being in its "chrysalis stage.

[16] In August 1914 she organised a Hadfield Girl Guide centre at the Ancoats University Settlement which functioned as a "modified labour bureau".

Guides volunteered their time in a variety of ways as part of the war effort, including clerical work, cleaning and acting as "patients" for trainee nurses to practice on.
