Farnsworth, Philo Taylor, 1906–71, American inventor, b. Beaver, Utah, grad. Brigham Young Univ., 1925. He demonstrated (1927) a working model of a television system. His "dissector tube" (called the orthicon), like V. K. Zworykin's iconoscope, is a means of dividing an image into particles whose light values, when transmitted, are capable of being restored to form a replica of the original image. In 1938 he became research director of the Farnsworth Television and Radio Corporation.
