1. Philo Farnsworth. “On September 7, 1927, in his lab at the bottom of Telegraph Hill, 21-year old Farnsworth’s invention transmitted the blurry image of a line. With his “Lab Gang,” as the researchers called themselves, he perfected the technology, in the next year transmitting shapes, and few years later, sending signals from the lab at 202 Green Street to the Merchants’ Exchange Building on Battery and Washington – 8 blocks away.” (Submitted on July 17, 2009.)
