Charlotte von Mahlsdorf, German philanthropist, founded the Gründerzeit Museum (born 1928)

Charlotte von Mahlsdorf was a well-known transgender woman in East Germany and founded the Gründerzeit Museum in Berlin-Mahlsdorf. Later she became a LGBT-icon in Germany because of Rosa von Praunheim's biopic I Am My Own Woman (1992).

The Gründerzeit was a period of European economic history in mid- and late-19th century Germany and Austria-Hungary between industrialization and the great stock market crash of 1873. Its name is derived from the many incorporations of companies that occurred in the years between the Franco-Prussian War and the panic of 1873.
