Arnold O. Beckman, the scientific visionary whose inventions
transformed chemistry and made him so wealthy that he became one of
the country's major philanthropists, died Tuesday. He was 104.
....
Beckman earned 14 patents, including those for the potentiometer, a
variable electrical resistor similar to the volume knob on a radio,
and the spectrophotometer, which allowed scientists to quickly
determine the chemical makeup of a compound by measuring the intensity
of various wavelengths in a spectrum of light.
But it was one of his first -- U.S. Patent No. 2,058,761 -- that
earned him a place in the National Inventors Hall of Fame in Akron,
Ohio: the pH meter, a simple device that measured the sourness in
lemons.
