The daughter of a Protestant military chaplain, Minna Tube was born on June 5, 1881[2] in Metz[3] then a German city.
She met the draftsman and painter Max Beckmann in 1903 at the Grand-Ducal Saxon Art School in Weimar.
After her divorce, Minna continued her singing career, but she remained linked to Max Beckmann for the rest of her life.
In 1945, in front of the advance of the American and Soviet armies, she took refuge in Gauting, in Bavaria.
[2] While many of Max Beckmann's paintings represent her, Minna Tube did not leave any sound recordings.
