Giovanni Fontana was a 15th-century Italian engineer and inventor. His designs included everything from systems for retrieving sunken ships and automating the defence of fortifications to measuring time and producing music. He created locks, clocks, and magic lanterns. If you like what you hear and want to chip in to support the podcast, my Patreon is here.
