There are many important jobs that women have never held. Even when the glass ceiling is shattered and a woman reaches new, historic heights, it can take years before others follow.

In fields such as public service, entertainment, sports, and business, many of the highest honors have only been achieved by one woman.

Here are 21 leadership positions, titles, and awards that only one woman in history has held.
