Question: The first working all-electronic TV image was transmitted in 1927 by a 21-year-old who’d first dreamed up the idea as a teenage farm boy. In which California city was his lab?

Answer: San Francisco. Philo Taylor Farnsworth transmitted the first successful all-electronic television image at his lab at 202 Green Street on Sept. 7, 1927, when he was 21 years old. Born in Utah and raised partly on an Idaho farm, Farnsworth later said he conceived the idea for electronic television while plowing a field as a teenager. The site is now California Historical Landmark No. 941.
