A person who practices or advocates for benevolence; someone devoted to charitable works and helping others.
From benevolence combined with the -ist suffix, which typically denotes a person who practices or believes in something. This is a rare term that never gained widespread usage in English.
Benevolist is such a rare word that it's barely in modern dictionaries, yet it perfectly describes philanthropists and charitable workers—sometimes the best words for describing people and their values are the ones nobody uses anymore.
