A grantmaker is betting a TV show for teen girls can help narrow the STEM gender gap

Dallas philanthropist Lyda Hill has devoted much of her giving to tackling social problems through science. Her Lyda Hill Philanthropies supports museums, basic research, and programs like National Geographic Explorers.

Over the last few years, the grantmaker also has ventured into media production: financing and helping develop a TV series, “Mission Unstoppable,” aimed at girls aged 13 to 17, which features women succeeding in science, technology, engineering, and math, or STEM, careers.
