Invented in San Francisco Walking Tour: GG Bridge Anniversary Edition

Science and creativity in a city of innovation

Bridge architect Joseph Strauss devised more than the world's most iconic span: he came up with the hard hat, to protect his team of fearless workers, along with many other inventions. 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.

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.

Please note: This tour does NOT take place on the GG Bridge. We'll follow our usual downtown route, with views of the Bay Bridge and discussion of bridge-related inventions, as well as the many other innovations covered on the regular tour.
