Invented in San Francisco Walking Tour: Special Bridge Anniversary Edition

Bridge architect Joseph Strauss devised more than the world's most iconic span: he worked with San Francisco's Edward Bullard to come up with a safety hat designed especialy for bridge workers. The Golden Gate bridge was the world's first official "hard hat zone." Celebrate the birthday of our beautiful bridge by discovering the inventions our Bay Area bridges have brought us on this special edition of the popular Invented in San Francisco Walking Tour.

Please note: This tour follows our usual downtown route, and does NOT take place on the GG Bridge.

San Francisco's creative nature inspired innovation long before the silicon chip: Some of the world's most influential inventions were dreamed up by San Franciscan tinkerers. On this tour, we explore seven surprising stories of innovation 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.
