Schlaffhorst was born in Memel. She advocated a system of breathing gymnastics with physical education with Hedwig Andersen.

In 1897, she translated his book ''The Art of Breathing'' into German. The book formed the basis of her Rotenburger Breathing School (Rotenburg School of Respiration).

The Rotenburg School of Respiration became the Schlaffhorst-Andersen School in 1982. Provided by Wikipedia
