Other forms: animateurs
Something like a community music festival, a sports camp, or the building of a neighborhood playground needs an animateur to make it happen — a person to get it started, organize it, and recruit people from the community to participate.
Animateurs can work in a variety of different fields. The term originally comes from the arts, and some do work in that field, perhaps leading workshops for community members to learn painting or music appreciation. Others work in institutions such as homes for elderly or disabled people, planning recreational programs for the residents. Still others help with projects such as setting up a community garden or preparing a hiking trail for use. The word animateur comes from French, literally meaning "one who brings to life."
