# Edward Kasner facts for kids

**Edward Kasner** (1878–1955) is an American mathematician (person who studies math). He is famous for creating the word googol and the word googolplex.

Kasner went to Columbia University and received his Ph.D. (a degree (measure) of learning) in 1899.

Around 1920, Kasner decided to make a good, catchy name for a very big number (one, followed by a hundred zeros). While he was walking with his nephews Milton (c. 1911–1980) and Edwin Sirotta in New Jersey's Palisades, Kasner asked them to think of good names. Milton was the one who said "googol".

In 1940, with James Roy Newman, Kasner made a book about math called *Mathematics and the Imagination* ISBN: 0486417034. It was in this book that the name "googol" was first used.

The website Google was named after Kasner's number googol.
