ニルス・ゲーゼ
In 1829, he married Emma Sophie Amalie Zinn (1807–1851), herself a composer. One of their sons, Emil Hartmann (1836–1898) also became a renowned composer, while their son Carl Christian Ernst Hartmann (1837–1901) became a sculptor. Two of their daughters both married composers; Emma Sophie (b. 1831) married Niels Gade and Clara (b. 1839) married August Winding (1835–1899). Many important later Danish artists, such as the composer Niels Viggo Bentzon and the director Lars von Trier descend from Hartmann.
