Erika Eiffel is a former pilot, two-time archery world champion and martial arts champion. Eiffel is orientated towards relationships with objects, and identifies as being an Objectum-Sexual (OS) person. In 2008, she founded OS Internationale, an organisation that supports those who identify as having OS. She works to raise awareness for OS people in the face of media distortion and sexualisation of OS relationships. Eiffel’s name comes from her personal commitment to her love for bridges and the Eiffel Tower, which she married in 2007. Her 20-year relationship with the Berlin Wall also inspired a musical theatre production titled Erika's Wall.
