As the Czech ambassador to the United States, H. E. Petr Gandalovič noted in his foreword to this book that Míla Rechcígl has written a monumental work representing a culmination of his life achievement as a historian of Czech America. The Encyclopedia of Bohemian and Czech American Biography is a unique and unparalleled publication. The enormity of this undertaking is reflected in the fact that it covers a universe, starting a few decades after the discovery of the New World, through the escapades and significant contributions of Bohemian Jesuits and Moravian brethren in the seventeenth and eighteenth centuries, the mass migration of the Czechs after the revolutionary year of 1848, and up to the early years of the twentieth century and the influx of refugees from Nazism and communism. The encyclopedia has been planned as a representative, a comprehensive and authoritative reference tool, encompassing over 7,500 biographies. This prodigious and unparalleled encyclopedic vade mecum, reflecting enduring contributions of notable Americans with Czech roots, is not only an invaluable tool for all researchers and students of Czech American history but is also a carte blanche for the Czech Republic, which considers Czech Americans as their own and as a part of its magnificent cultural history.
