Humanitarians

In the 1913 Websters the definition for the word "humanitarian" was defined as "One who is actively concerned in promoting the welfare of his kind; a philanthropist." This was listed as a "recent" definition.
The last century has seen many great humanitarians - famous and not - who live up to this definition.

Scientology Volunteer Ministers who travel to parts unknown simply to help those in need in times of disaster are humanitarians.
