Alex Subrizi devotes some of his free time to steering the Archivio Giuliano Ghelli, a not-for-profit associazione culturale founded in 2015 by the siblings of the late Italian painter Giuliano Ghelli (1944-2014). Both Alex and the Archivio are based in Italy but Alex grew up and spent many years in the US; he usually consults Wikipedia in its English language edition.
Hobbies, besides the Archivio Ghelli and listening to music at every possible opportunity, include reading history and art history, watching old movies, Indian cooking, the occasional hike, the occasional run, and taking pictures.
