164 South Park

San Francisco, CA

This unassuming address in San Francisco's South Park neighborhood โ€” the leafy oval that anchored the city's original startup district โ€” is where both Twitter and Instagram were born. Odeo, the podcasting company that pivoted into Twitter in 2006, worked from South Park, and Instagram launched nearby in 2010 before its record-setting acquisition. The tiny park sits at the historic heart of the SoMa tech scene.

Philo T Farnsworth

San Francisco, CA

This monument honors Philo T. Farnsworth, the farm-boy genius who conceived electronic television as a teenager and, in a San Francisco laboratory in 1927, transmitted the first all-electronic TV image. Working far from the corporate research giants, he pieced together the technology that would remake communication, culture, and daily life around the world. San Francisco was where his boldest breakthroughs took shape.

Eadweard James Muybridge

San Francisco, CA

This monument honors Eadweard James Muybridge (1830-1904), the pioneering photographer who, working in and around San Francisco, proved through rapid sequential photography that a galloping horse briefly lifts all four hooves off the ground. His motion studies laid the groundwork for the moving image, earning him the title "Father of Cinema." Muybridge's experiments in 1870s California bridged still photography and the birth of film.

North Dutch Windmill, Golden Gate Park

San Francisco, CA

The North Dutch Windmill was built in 1902 at the western edge of Golden Gate Park, where it once pumped groundwater to irrigate the sprawling greenery reclaimed from sand dunes. By the late 20th century it had fallen into disrepair, and a 1981 restoration โ€” driven by Eleanor Rossi Crabtree's fundraising and volunteer labor from a Naval Reserve construction battalion โ€” brought it back to life. It remains a beloved San Francisco landmark.
