E Clampus Vitus is both a historical and fraternal organization. Although ancient in origin, it reached its peak during the tumultuous days of The Great California Gold Rush. A Member of E Clampus Vitus is commonly called a "Clamper." The latter-day members of this organization, which boasts between 75,000 and 80,000 active members, attempt to uphold the traditions of fellowship, good spirits, and fun. Like their forbearers, the modern "Clampers" are dedicated to the care and protection of the Widow* (known as "Widders" to Clampers) and the Orphan. * But especially the Widders.
