Many men have laid claim to the title "father of television," but

Philo T. Farnsworth is the true genius behind what may be the most influential invention of our

time. Driven by his obsession to

demonstrate his idea by the age of twenty Farnsworth was

operating his own laboratory above a garage in San

Francisco and filing for patents. The resulting publicity caught the

attention of RCA tycoon David Sarnoff, who became

determined to control television in the same way he monopolized

radio.
