CARL G. EILERS, 1925 – 2008

Carl G. Eilers is considered the “Father of Stereo FM Radio
and Stereo Television Sound,” for pioneering work during
his 50-year career at Zenith Electronics LLC. Eilers died June
20 in his River Forest, Ill., home. He was 83.
   Eilers joined Zenith in 1948 after receiving his bachelor’s
degree in electrical engineering from Purdue University.
Through 1961, he worked on the world’s first pay television
system, Zenith Phonevision, earning key patents on sub-
scription TV technologies.
   During that period, while pursuing his master’s degree
in electrical engineering, which he earned in 1956 from
Northwestern University, Eilers led Zenith’s development
effort on stereophonic FM radio broadcasting. The stereo
FM standard he co-developed was first adopted by the Fed-
eral Communications Commission in 1961 and is still in use
today around the world.
   Two decades later, as R&D manager, Eilers co-developed
the stereo TV system adopted by the industry in 1984.
Through the 1990s, Eilers was a key member of Zenith’s           Stereo TV co-inventor, the late Carl G. Eilers, left, in the Zenith
high definition television (HDTV) development team.              R&D Lab with fellow engineer Pieter Fockens in 1984 when the

Storing Your Life
Thomas Coughlin

Data storage has become a major
topic in consumer electronics in
recent years. The demand for stor-
age keeps increasing at an incredi-
ble rate – just ask your editor, who
has to add storage to his home net-
work every few months, it seems.
And that’s not counting the many
devices coming into his home with
their own storage capability – we
have absolutely no idea how much
storage exists in our home. The
monster hard drive we installed for
backup just a few years ago is com-

just too small. It was state-of-the-
art when we bought it, but you
can’t buy one that small any more.
