Edward Kasner (1878 - 1955) was an American mathematician, mostly known for his role in the origin of the word googol.
Kasner studied at Columbia University under Cassius Keyser. He received his Ph.D. in 1899; his dissertation was titled The Invariant Theory of the Inversion Group.
In 1921 he discovered the Kasner dust solutions of the Einstein field equation in general relativity, which are today regarded as an important example. In 1934, he published an classic monograph on differential equations and dynamical systems.
In the late 1930s, Kasner was asked to come up with a name for a very large number. He outsourced this task to his nine-year-old nephew, Milton Sirotta, who in turn coined the word "googol." A googol is 10 raised to the 100th power (i.e., a 1 followed by a hundred zeros.)
In 1940, with James Roy Newman, Kasner authored a semi-popular book surveying the entire field of mathematics.
