Some of the world’s most influential inventions were dreamed up by San Franciscan tinkerers. On this tour, we explore seven surprising stories—from tech to tunes to treats—that exemplify San Francisco as a hotbed of creative thinking for nearly two centuries. We’ll investigate the science behind some of these inventions, discuss how the nature of what we patent has evolved over time, and explore our own ability to think outside the box.
