The eldest son Otto Goldschmidt was a composer, conductor and pianist, who married the Swedish Nightingale, soprano Jenny Lind.
"[2] In 1848, Goldschmidt became co-founder of the Frauenverein zur Bekämpfung und Ausgleichung religiöser Vorurteile, a women's association to combat and reduce religious prejudice.
This led to the foundation of the Hochschule für das weibliche Geschlecht (1850–1852), the first institution of higher education for women in Germany.
She also defended the idea of higher education for women to opponents like Karl Gutzkow or against Prussian administration which had been established in Altona in 1867.
Johanna Goldschmidt stood in contact with Clara Schumann, Johannes Brahms and the educator Adolph Diesterweg.
