The Zosimades (Greek, Modern (1453-);: Ζωσιμάδες) or Zosimas brothers were 18th-19th century Greek benefactors and merchants.
The Zosimades were six brothers:
They were born in Ioannina, a city that was under Ottoman rule and a major center of the Greek Enlightenment that time. Their father was a local merchant, Panagis Zosimas. In 1775, Nikolaos, Theodosios and Michael started their trading activities in Livorno, Italy, while Ioannis, Anastasios and Zois ran their trade business in Nizhyn (Ukraine) and then in Moscow. Their trade network soon became profitable and they managed to make a fortune.
After Theodosis' death (1793), he wrote in his testament that they should financially support the education of their home city Ioannina. So they donated astronomical amounts of money for the establishment and function of various schools and public libraries. Another huge donation went for the National Library, of Adamantios Korais, one of the major contributors of the Greek Enlightenment movement. Apart from educational institutions, orphanages were also financed. The Zosimades also subsidized the publication of several books.
At 1820, after Zois' death, they supported the establishment of a new school in their home place, which became known as Zosimaia. This institution would become the center of Greek education the following century in the region of Epirus.
During the following outbreak of the Greek War of Independence (1821–1830) the remaining Zosimades became active members of the patriotic organization Philiki Etaireia and supported financially the struggle. Zosimades also completely financed the erection of the Monetary Museum of Athens, donating their personal collection of Ancient Greek and Roman currency, as well as the orphanage in Patmos.
