Lajos Kossuth was a Hungarian politican in the 19th century. He became one of the leading personalities of a revolution and war of independence (that was started in order to break away from the Austrian Empire). After the war KOssuth emigrated to the USA. Check the link as a reference.

Lajos, BTW is the Hungarian form of
Louis)
