English-born, Lafount moved to the United States as a teenager and grew up in Utah. He managed several local businesses and was active in The Church of Jesus Christ of Latter-day Saints. Appointed to the Federal Radio Commission by President Calvin Coolidge, he was in charge of the zone covering the Western United States. Lafount played an important part in developments and decisions regarding the regulation of the broadcasting industry in the U.S., favoring perspectives that saw radio broadcasting as a fundamentally commercial enterprise. He was also an early influence in making radio airtime available to political candidates and parties. (Full article...)

Image 1Diagram of the electric fields (E) and magnetic fields (H) of radio waves emitted by a monopole radio transmitting antenna (small dark vertical line in the center). The E and H fields are perpendicular, as implied by the phase diagram in the lower right. (from Radio wave)
Image 2British Post Office engineers inspect Guglielmo Marconi's wireless telegraphy (radio) equipment in 1897. (from History of radio)
Image 13Animated diagram of a half-wave dipole antenna receiving a radio wave. The antenna consists of two metal rods connected to a receiver R. The electric field (E, green arrows) of the incoming wave pushes the electrons in the rods back and forth, charging the ends alternately positive (+) and negative (-). Since the length of the antenna is one half the wavelength of the wave, the oscillating field induces standing waves of voltage (V, represented by red band) and current in the rods. The oscillating currents (black arrows) flow down the transmission line and through the receiver (represented by the resistance R). (from Radio wave)
