Ellen Evans was a famous scientist, along with her husband Ralph Evans. The couple lived in Smallville and have gone on scientific expeditions together. One day, while using a hot air balloon to photograph an unusual radioactive comet, the two of them were blinded by the radiations. Soon after, they met and adopted an amnisiac Supergirl, who called herself Gloria Smith. They soon discovered her secret identity and helped her to maintain it, until Superman sprinkled Smallville with a gas that made the entire town forget Supergirl's existence.
