Cronbach's alpha, a coefficient of reliability developed by Lee Cronbach
It was first named alpha by Lee Cronbach in 1951, as he had intended to continue with further coefficients.
His modesty is perhaps one of the reasons that the generalization of the Kuder-Richardson's (1937) formulation of the coefficient of internal consistency reliability to a continuous case is generally ascribed to Lee Cronbach (1951), even though this generalization was already made a decade earlier (Hoyt, 1941).

On October 7, 1917 Cronbach married Rose Hentel, a teacher at the Free Synagogue in New York whom he met during his time there.
Among them are percent agreement, Scott's π, Cohen's κ, Krippendorf's α, Pearson's correlation coefficient r, Spearman's rank correlation coefficient ρ, and Lin's concordance correlation coefficient.
