; officially declared dead on 31 December 1944) was the professional pseudonym of Else Ernestine Neuländer-Simon who was a German Jewish photographer renowned for her dreamlike, multiple exposed images.

[6] She embraced the modernist approach using technical composition and avant-garde imagery, both capturing the sexual revolution of the period and emphasizing the female form in ungendered ways, which allowed her flexibility as an artist.

In part, the ambiguity of the Nazi policies,[9] her assimilation into the non-Jewish community,[7] and her employment of ten[2] assistants who were not Jewish, led Yva to a false sense of safety.

She did not experience anti-Semitism from her advertising and fashion clients,[9] and first moved to a larger studio on Bleibtreustraße before relocating again the following year to Schlüterstraße,[2] shortly after her marriage.

That same year, she Aryanized her firm and transferred ownership to her friend, the art historian Charlotte Weidler, to enable the business to continue operations.

[2] Her husband convinced her to abandon the plan and remain in Germany, hoping that things would improve,[9] because he could not envision starting over in a new place in which he didn't even speak the language.

[7] Some efforts were made in 1942 for the couple to leave Germany, as after their arrest 34 crates of their belongings, most full of her photographic furnishings, were identified at the Hamburg port.

No transport lists for this deportation have clarified the whereabouts of the couple, though the Jewish Registry at Yad Vashem shows Alfred Simon was murdered at Majdanek.
