Frank Albert Benford Jr. (July 10, 1883[1] – December 4, 1948) was an American electrical engineer and physicist best known for rediscovering and generalizing Benford's Law, a statistical statement about the occurrence of digits in lists of data.[2]

Benford is also known for having devised, in 1937, an instrument for measuring the refractive index of glass.[1] An expert in optical measurements, he published 109 papers in the fields of optics and mathematics and was granted 20 patents on optical devices.

Early life[edit]

He was born in Johnstown, Pennsylvania.[1] His date of birth is given variously as May 29 or July 10, 1883.[1] At the age of 6 his family home was destroyed by the Johnstown Flood.[1]


He graduated from the University of Michigan in 1910.


Benford worked for General Electric, first in the Illuminating Engineering Laboratory for 18 years, then the Research Laboratory for 20 years until retiring in July 1948.


He died suddenly at his home on December 4, 1948.
