A pioneering woman in the medical world, Herta published more than 250 scientific papers, including numerous articles on the effects on humans of strontium-90, a major radioactive component of fallout from the atomic bomb tests of the '40s and '50s. She was instrumental in describing mechanisms to rid the body of this deadly isotope, information that was to prove invaluable years later when she helped save lives following the nuclear accident at Three Mile Island.… Mostly, Herta taught us that if you have focus, work hard and dream big you can make major achievements that make the world a better place.
