Question: What is the birthdate of this American film director, screenwriter, author, actor, stand up comedian, journalist, visual artist, and art collector, who was a lifelong friend and collaborator of Harris Glenn Milstead? 
Context: The Archivio di Nuova Scrittura ("Archive of New Writing", "ANS") is a cultural association founded in 1988 in Milan, Italy by art collector Paolo Della Grazia.  The archive preserves a large artistic and documentary heritage about any form of artistic expression featuring the use of both the word and the sign.  Born from the encounter between Della Grazia and artist Ugo Carrega, in the 1990s the ANS became the main Italian research center on visual poetry, organizing exhibitions, meetings and other cultural events.  In 1998 the Archivio di Nuova Scrittura was deposited in part at the Mart in Rovereto (library, archives and some artworks) and in part at the Museion in Bozen (artworks only).  The artwork section of the ANS includes about 1,600 works by international artists at Mart and about 2,000 at Museion.  The ANS archives preserve, apart from the internal archive of the association (ANS fonds), the Fraccaro-Carrega fonds, containing the papers of collector Marco Fraccaro and visual poet Ugo Carrega.  The library section, preserved at Mart, contains more than 10,000 volumes, among them 600 artist's books and hundreds of futurist first editions, and 500 art magazines including about 100 international artist's magazines.

Ishirō Honda (本多猪四郎 , Honda Ishirō , May 7, 1911 – February 28, 1993) , sometimes miscredited in foreign releases as "Inoshiro Honda", was a Japanese film director.  He is best known for his "kaiju" and "tokusatsu" films, including several entries in the "Godzilla" series, but also worked extensively in the documentary and war genres earlier in his career.

William James Stillman (June 1, 1828 – July 6, 1901) was an American journalist, diplomat, author, historian, and photographer.  Educated as an artist, Stillman subsequently converted to the profession of journalism, working primarily as a war correspondent in Crete and the Balkans, where he served as his own photographer.  For a time, he also served as United States ambassador in Rome, and afterward in Crete during the Cretan insurrections.  He helped to train the young Arthur Evans as a war correspondent in the Balkans, and remained a lifelong friend and confidant of Evans.  Later in life, he seriously considered taking over the excavation at Knossos from Minos Kalokairinos, who had been stopped from further excavation by the Cretan Assembly; he was, however, prevented from pursuing that goal further by a failure to obtain a firman, or permission to excavate.  Stillman wrote several books, one of which, his "Autobiography of a Journalist", suggests that he viewed himself primarily as a writer.
