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."
