The film How They Hanged Greiser (2004) dates back to the artist’s student days. It was exhibited at WRO 05 and as part of the Encounters Film Festival in Bristol (2005).

In the film, Piotr Bosacki recounts the true story of Arthur Greiser, the governor of the Third Reich in Poznań, sentenced to death by hanging in 1946. The narrator is an elderly woman – an eyewitness to the last public execution of a Nazi war criminal in Poland. According to her account, Greiser was sympathetic to the Poles. She mentions a woman who worked for Greiser and cried during his execution, proclaiming that he was innocent and had done no harm to anyone. Historical documents confirm the cruel methods of Germanisation and extermination of Polish civilians employed by Greiser.

Piotr Bosacki, born in 1977 in Poznań, graduated from a secondary art school and a secondary music school. From 1999 to 2004 he studied at the Academy of Fine Arts in Poznań (currently known as the UAP), where he now lectures at the Faculty of Multimedia. Member of the informal art group Penerstwo and Wojtek Bąkowski’s band KOT (disbanded in 2011). In 2012, he published The Structure of Elements, a dissertation on the work of art as a linguistic construction.

The artist works at the intersection of many disciplines – music, art, animation, and literature. Films are his favourite medium. Minimalist, poetic, witty, and full of contradictions, they are able to convey complex philosophical and existential issues with the use of relatively simple means.
