Russian-Germans authors were spoilt for choice (not sure what spoilt for choice means here): they wrote in German, Russian or in a Low German dialect and sometimes even in two or three languages. Dominik Hollmann, Viktor Klein and Viktor Heinz were examples for those trilingual authors.
The content of Russian-German literature can sometimes be recognized as well.
Urban Germans: Germans invested a lot of strength and energy in the development and even the foundation of many areas of Russian musical life. One example of the influence of Germans was the foundation and development of the Russian conservatories, music theatres, musicology and the as well the musical infrastructure, especially in St. Petersburg and Moscow.
They are barely known in Germany, but still very popular in Russia to this day: 121 painters and sculptors with a German background like Johann Gottfried Tannauer, Georg Christopher Grooth, Karl Brüllow and Peter Klodt von Jurgensburg. They have all worked before the Soviet Union times.
The particularity on their art is the mixture of cultures and worlds.
Even German architects have left their mark on the Russian landscape. Particularly significant is this mark in St. Petersburg. Leionen (?) says:
"If you take a closer look into the history of the city it becomes evident to what extent German architects participated in building and designing the city over centuries. Some of them came from Germany into the new Russian capital and others were native Petersburger Germans. Approximately 240 names of German architectures could be found that were all active in St. Petersburg.
In the bigger cities of Russia, Germans were significantly participating in building and establishing the theatre. For example, pastor Johann Gregori, teacher G. Hübner, organ builder Timofej Hasenkrug and Dr. Blumentrost founded the first court theatre in Moscow.
In the rural area, there were no established theatres. In these regions, just like in other countries, joint amateur plays were organized and especially on Christmas and Easter little performances were presented. The direction was usually led by teachers or Christian leaders.
