    Title: Oblężenie Warszawy w fotografii Juliena Bryana / Siege of Warsaw in the photographs of Julien Bryan
    Author: Julien Hequembourg Bryan
    Language: polski

    Subjects: N/A
    Publisher: Wydawnictwo: Instytut Pamięci Narodowej
    ISBN: 9788376291680
    Total pages: 37

    Description:

    Książka jest pierwszą tak obszerną i wszechstronną prezentacją dorobku Juliena Bryana. Jej głównym tematem jest oblężenie Warszawy przez wojska niemieckie w 1939 r., a szczególnie losy cywilnych mieszkańców stolicy Polski, widziane okiem amerykańskiego fotografa. Oprócz szerokiego wyboru zdjęć, w tomie znalazły się nietłumaczone wcześniej na język polski reportaże Bryana: „Oblężenie” z 1939 r. i „Warszawa – ponowne odwiedziny” z 1959 r., oraz relacje Polaków, którzy mu pomagali: zapis radiowego przemówienia kpt. dypl. Władysława Polesińskiego „Na zgliszczach Pragi” i wspomnienie Stefana B. T. Radlińskiego „Z Julienem Bryanem we wrześniowej Warszawie”. „Wprowadzenie” Jacka Zygmunta Sawickiego i tekst Tomasza Stempowskiego są współczesną próbą umieszczenia dorobku amerykańskiego fotografa w szerszym kontekście historycznym.

    Na płycie DVD zamieszczono film „Oblężenie” z 1940 r., udostępniony przez Filmotekę Narodową, oraz zapis wystąpienia Juliena Bryana w Polskim Radio z 16 IX 1939 r.

    Zebranie w ramach jednej publikacji tak różnorodnych materiałów ma na celu przekazanie możliwie wielu kontekstów. Daje też unikalną okazję, by przyjrzeć się wzajemnym relacjom tekstu i obrazu w dokumentowaniu historii. Jak już w 1940 r. we wstępie do albumu „Siege” napisał Maurice Hindus, fotografie Juliena Bryana nie tylko należy oglądać i podziwiać, ale nieustannie studiować. W piękny i wzruszający sposób odtwarzają one niezwykle ważny rozdział historii i dramat naszych czasów.
