Carla Tannhauser (Earth-1: Pre-Crisis)

"I've made so many mistakes in my life. Maybe I'm the one who needs fixing."

- Carla Tannhauser to Frost

Carla Tannhauser is a renowned bio-engineer and the CEO of Tannhauser Industries.

Helping Frost
After being shot by Dr. Light's Photon Rifle, Caitlin Snow tried to use her ice healing. However, it did not succeed and she needed medical help. Ralph Dibny then convinced her to ask for Tannhauser's help and she arrived at the apartment for a test.

When Tannhauser struggled with the test, she unintentionally told Frost that it would be faster with Snow's help. Knowing it hurt Frost's feelings, Tannhauser apologized to Frost and they had a conversation about the family while working together. Later, Tannhauser brought Snow away for further recovery after she convinced Barry Allen that his strength is love.
