    John Vincent Atanasoff, 1903-10-04 - 1995-06-15.  An
   American mathemetical physicist, and the inventor of the
   electronic digital computer.  Between 1937 and 1942 he built
   the Atanasoff-Berry Computer with Clifford Berry, at the
   Iowa State University.

   Atanasoff was born on 1903-10-04 in Hamilton, New York.  In
   1925, he got a Bachelor of Science degree in Electrical
   Engineering from the University of Florida.  In 1926 he
   received a Master's degree in Maths from Iowa State
   University.  He received a PhD as a theoretical physicist from
   the University of Wisconsin in 1930.

   While an associate professor of mathematics and physics at
   Iowa State University, Atanasoff began to envision a digital
   computational device, believing analogue devices to be too
   restrictive.  Whilst working on his electronic digital
   computer, Atanasoff was introduced to a graduate student
   named Clifford Berry, who helped him build the computer.

   The first prototype of the Atanasoff-Berry Computer was
   demonstrated in December 1939.  Although no patent was awarded
   for the new computer, in 1973 US District Judge Earl R.
   Larson declared Atanasoff the inventor of the digital computer
   (declaring the ENIAC patent invalid).

   Atanasoff was awarded the National Medal of Technology by US
   President Bush on 1990-11-13.  He died following a stroke on
   1995-06-15.
