Dagmar Nordstrom (December 12, 1903 – April 9, 1976) was an American composer, pianist and singer. She performed together with her sister Siggie as a cabaret singing duo known as The Nordstrom Sisters.
Dagmar Nordstrom was born in Chicago, Illinois. She was the second daughter of Anna and Alexander Nordstrom. The family were of Swedish and Norwegian extraction. Dagmar was married briefly to a society playboy, but lived most of her life with her older sister after the death of Siggie's husband, Samuel Ferebee Williams (1883-1931).
Dagmar and Siggie had a flat in London for a year in 1939 when they were the resident performers at The Ritz. With the exception of their October trips to Bad Gastein for the baths, they regularly performed either in clubs in New York City or on board transatlantic ocean liners, most commonly on the Cunard Line and Norwegian America Line. The duo were on the maiden around the world voyage of the combined ocean liner/cruise ship MS Sagafjord.
Dagmar wrote the music for Remembering You, a foxtrot which was published as sheet music and a full orchestration in 1940. During the 1940s she and her sister were often on the radio and through the 1960s when they were not otherwise engaged as a team, Dagmar would at times take an assignment alone playing in a club.
During the 1920s she cut piano rolls for Steinway and Duo-Art. These included:
