# Philo Farnsworth

Philo Taylor Farnsworth (Indiana Springs, perto de Beaver, Utah, EUA, 19 de agosto de 1906 — Salt Lake City, Utah, EUA, 11 de março de 1971) foi um inventor estadunidense e um dos pioneiros da televisão. Ele fez várias contribuições que foram cruciais para o desenvolvimento de todas as televisões eletrônicas.
Em 1927, Farnsworth descobriu um sistema dissecador de imagens por raios catódicos e conseguiu demonstrar a primeira transmissão eletrônica de televisão do mundo. Ele é um dos personagens da vida real na biografia semi-ficcional "Carter Vence o Diabo" sobre o mágico Charles Carter nos anos 20. O livro narra uma versão da primeira demonstração pública da televisão.
Segundo os filhos, quando Philo Farnsworth viu a evolução dos programas de televisão de programas educacionais para programas somente de entretenimento, ele ficou decepcionado.
Em uma entrevista de 1996, filmada pela Academia de Artes & Ciências Televisivas, Elma Farnsworth reconta sobre a mudança de coração de Philo sobre o valor de televisão, depois de ver como mostrou homens andando na lua, em tempo real, para milhões de telespectadores:
    Entrevistador: "O dissecador de imagens foi usado para enviar vídeo da lua para a terra."
    Elma Farnsworth: "Certo."
    Entrevistador: "O que Philo achou disso?"
    Elma Farnsworth: "Estávamos olhando, e, quando Neil Armstrong aterrizou na lua, Phil me olhou e disse, 'Bem, isto fez tudo valer a pena.' Antes disso, ele não tinha certeza [que televisão tinha valor]."
    Philo Farnsworth era mórmon, membro ativo de A Igreja de Jesus Cristo dos Santos dos Últimos Dias, e portador do Sacerdócio de Melquisedeque.
