The Jozef A. Mikuš fonds consists of various documents personally collected by Dr. Mikuš over a lifetime of activities as a diplomat, a jurist, a political activist, an immigrant, a teacher, an officer in various nationalist and political associations, and as a simple citizen. It is very much a “personal” collection of documents that reflects Dr. Mikuš’ views and interests on a multitude of topics, and bears witness to his lifetime involvement in the political history of his country of origin, Slovakia, in the life and struggles of his countrymen, the Slovak people, and in the social and political life of his country of adoption after World War II, the United States of America. Gravitating around these major focal points are documents on a variety of subjects from religion to economy, from freedom of speech to education, political parties to arts and culture, famous politicians to nationalist writers, from nuclear arms to aid programs.
