Together with her husband and actor Georg Alexander she founded her own film company which produced besides an Aud-Egede-Nissen serial also a Gerd-Egede-Nissen and a Ada-van-Ehlers serial. Ada van Ehlers impersonated the first female detective.
After the sound film "Zwischen Nacht und Morgen" (1931) she retired from the film business. Her name came up only one time more in the movie "Hansen og Hansen" (1941).
The Norwegian actress Aud Egede Nissen became an actress because of her sisters Gerd Egede Nissen and Ada van Ehlers who both were actresses too.
