Leo Katz (29 November 1914 in Detroit – 6 May 1976) was an American statistician.
Katz largely contributed to the area of Social Network Analysis.
In 1953, he introduced a centrality measure named Katz centrality that computes the degree of influence of an actor in a social network.
The computation already outlined the algorithm today known as PageRank.
[1] In 1956 he was elected as a Fellow of the American Statistical Association.
