AT A GLANCE:
Electrical engineer and inventor Ernst Fredrick Werner Alexanderson
developed pioneering technological concepts during the early 20th century
that contributed to the birth of the broadcasting industry. Alexanderson's
numerous discoveries formed the basis for the technology that would make the
transmission of voice, music, and pictures possible; his more than 340
patents and affiliations with some of the world's foremost scientists and
business executives made him a central figure in the early years of
broadcasting and earned him a place on the list of the most prolific
U.S.-based inventors of all time. He designed the Alexanderson alternator, a
high-frequency generator for longwave transmission, which made modulated
(voice) radio broadcasts practical. Source:
