In 2021, the Museum of the Order of St John was successful in gaining funding from The National Lottery Heritage Fund and the St John Fellowship to undertake an intergenerational oral history project to explore, record, and celebrate the contributions made by young people to the work of St John Ambulance from 1922 to the present day, as part of the Museum’s celebration of the Cadet centenary in 2022. The project, designed in collaboration with current and former Cadets, involved training and supporting a group of Cadets from across England in capturing the experiences of ex-Cadets from the 1940s to the present day. The resulting oral histories would then be shared publicly in an online exhibition and accessioned into the Museum’s Archive to ensure their future accessibility and long-term preservation. This is a guide to the Cadet Voices archive collection held by the Museum.
