"Christmas is the festival of peace. Every year it comes in its own good time. But peace inside and among us can come only through persistent effort. This holiday reminds us that all people yearn for peace. Every year it admonishes us to be vigilant against the enemies of peace that lurk inside all of us, lest they cause harm not only at Christmastime but throughout the year."
Albert Einstein (1879-1955) From a Christmas message for an international radio broadcast, November 28, 1948. Einstein Archives 28-850.

Miroslav Havel (* 7.11.1881 in Teplice, † 8.7.1958 in Prague) Czech composer and Grandmaster, see wikipedia de, fr, it, lv, ru. "Miroslav Havel (Miroslav Košťál) composed Bohemian problems with a high degree of mastery and artistry. You can judge by yourself by the selfmate reproduced on wikipedia de. He edited the chess column of newspaper "Čas" (1920-1923) and was honoured by the publication of 500 of his problems in "Bohemian Garnets" in the White Christmas Series. He also wrote "České granáty" (1943)." Both books are available online.
From the "Kalenderblatt" in "Die Schwalbe," August 2008: "Dr. Miroslav Kostal, besser bekannt unter seinem Pseudonym Miroslav Havel (7.11.1881-8.7.1958) ist wohl bis heute der bekannteste Vertreter der böhmischen Problemschule. 1923 widmete A. C. White ihm in seiner Christmas-Serie den Band "Bohemian Garnets." Unter dem Titel "Ceske granaty" erschienen 1936 und 1943 weitere Aufgabensammlungen dieses böhmischen Klassikers."
