Richard Threlkeld Cox
Richard Threlkeld Cox (
1898 -
May 2,
1991) was a professor of
physics at
Johns Hopkins University, known for
Cox's theorem relating to the foundations of
probability.
He was born in
Portland, Oregon the son of attorney Lewis Cox and Elinor Junkin Cox. After Lewis Cox died, Elinor Cox married John Latane, who became a professor at Johns Hopkins University in 1913. In 1915 Richard enrolled at JHU to study physics, but his studies were cut short when he was drafted for
WW I. He stayed in the US after being drafted and returned to JHU after the war, completing his BA in 1920. He earned his PhD in 1924; his thesis was "A Study of Pfund's Pressure Gauge".
He taught at
New York University (NYU) from 1924 to 1943, before returning to JHU to teach. He studied probability theory, the scattering of electrons, and the discharges of
electric eels. Richard Cox's most important work was Cox's Theorem.
His wife
Shelby Shackleford (1899
Halifax, Virginia - 1987), whom he married in 1926, was an accomplished artist and illustrated Richard's books on electric eels.
His publications included:
* R. T. Cox, "Probability, Frequency, and Reasonable Expectation,"
Am. Jour. Phys., 14, 1-13, (1946).
* R. T. Cox,
The Algebra of Probable Inference, Johns Hopkins University Press, Baltimore, MD, (1961).
