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

[3] Benford is also known for having devised, in 1937, an instrument for measuring the refractive index of glass.

[1] At the age of 6 his family home was destroyed by the Johnstown Flood.

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 was working as a research physicist when he made the rediscovery of Benford's law, and spent years collecting data before publishing in 1938, citing more than 20,000 values from a diverse set of sources including statistics from baseball, atomic weights, the areas of rivers and numbering of articles in magazines.
