What Philly women have changed the world? The Science Center wants to know

The University City Science Center is celebrating Philadelphia women who have changed the world in the second round of its Innovators Walk of Fame. The names of the awardees will be engraved on a walkway at 37th and Market Streets this fall, along with the first group of awardees.
The Science Center is currently looking for nominations.
Nominate by June 15
The focus on women is welcome, as the first five awardees did not include any women.
