This ancient name, also spelled Caspar, is finally shedding its ghostly image and moving into the 21st century. Popular in the Netherlands and Scandinavia, where it's sometimes shorted to Cas, Casper could ride the style coattails of cousin Jasper. Casper was one of the Three Magi who brought gifts to the infant Jesus along with Melchior and Balthasar.
Some notable Caspers are one-time Secretary of Defense Casper Weinberger (called Cap) and actor Casper Van Dien, whose son is Casper Robert Van Dien III. Claudia Schiffer and Jenny Frost both used the names for their boys, while Jason Lee did a gender switch when he called his daughter Casper (sister of Pilot Inspektor).
