Erika Bos was born in Berlin, Germany in 1908 (some sources say 1910). She was the daughter of Dutch composer and pianist Coenraad V. Bos.
At the age of 10, she already had dance classes. She first attended public attention as a solo dancer in the 1920s and at 17 she was already a solo dancer in the city of Dortmund.
The beautiful dancer also followed speaking lessons by Ilka Grüning and soon she was spotted by the major German film studio Ufa.
Ery made her film début with Peter Lorre in the crime film Schuß im Morgengrauen/Shot at Dawn (Alfred Zeisler, 1932).
To her other films that year belong Liebe in Uniform/Love in Uniform (Georg Jacoby, 1932) and Unmögliche Liebe/Crown of Thorns (Ery Grünfeld, 1932) in which she appeared as a daughter of Asta Nielsen.

Escaping the holocaust
In 1933, Ery Bos played parts in Roman einer Nacht/Story of a Night (Carl Boese, 1933) and Der Zarewitsch/The Czarevitch (Victor Janson, 1933) starring Márta Eggerth.
After the Nazis had gained power in 1933, the Jewish actress soon fled the country, escaping the holocaust.
In 1934, her final films Mit dir durch dick und dünn/With you through thick and thin (Frans Seitz, 1934), Du bist entzückend, Rosmarie!/You are adorable, Rosmarie! (Hans von Wolzogen, 1934), Jede Frau hat ein Geheimnis/Every Woman Has a Secret (Max Obal, 1934) with Karin Hardt, and Grüß' mir die Lore noch einmal/Greet Lore again for me (Carl Heinz Wolff, 1934), could be seen in the German cinemas.
Ery Bos married Herbert Grünfeld (1908-1977) and lived as Ery Grünfeld in the US. She would never make another film.
In 2005, Erika Grünfeld died in Chappaqua (some sources say New Castle) in the state of New York at the age of 96.
