initiator
One who begins
An initiator is someone or something that begins or sets in motion a process, action, or event.
The word emphasizes the starting role rather than ongoing participation: She was the initiator of the reform movement, though others carried it forward.
In technical contexts, an initiator may be a device or substance that triggers a reaction, such as a blasting cap that detonates explosives or a chemical compound that starts polymerization.
