Who is William?

One of the most popular ancient Egyptian figures in the The Met collection—and sometimes referred to as the Museum's unofficial mascot—"William" was originally intended to provide protection and power in the afterlife. As the symbol of The Met William Society, this beloved hippopotamus embodies the enduring qualities of The Metropolitan Museum of Art.

In celebration of The Met William Society's twenty-fifth anniversary and the hundredth anniversary of William the Hippo at The Met, we are delighted to share a Museum article that explains the origins of William's name.
