ARLX027 Inventor W9CSX SK
 
Marvin Camras, W9CSX, who is credited with the invention of magnetic
tape recording, died June 23, 1995, in Evanston, Illinois.  He was
79 years old and lived in Glencoe, Illinois.
 
According to The New York Times, Camras worked and taught at the
Illinois Institute of Technology for more than 50 years.  As a
student in the late 1930s, he built a magnetic wire recorder and
later discovered that making recordings on magnetic tape made
splicing easier.  In 1944 he was awarded a patent on ''method and
means of magnetic recording,'' the Times said.
 
Camras received the National Medal of Technology in 1990.  He was
awarded more than 500 patents for his work and they were licensed to
more than 100 manufacturers.
 
The Times said that Camras exhibited an early aptitude for building
electrical devices, including a flashlight at age four and ''a
transmitter'' three years later.
 
Marvin Camras was first licensed as W9CSX in the late 1930s and held
that call sign until his death. Among his survivors are his wife,
Isabelle P. Camras, of Glencoe.
