Alston Scott Householder (5 May 1904 – 4 July 1993) was an American mathematician who specialized in mathematical biology and numerical analysis.

After receiving his doctorate, Householder concentrated on the field of mathematical biology, working with several other researchers with Nicolas Rashevsky at the University of Chicago.

[5] In 1946, Householder joined the Mathematics Division of the Oak Ridge National Laboratory, where he was appointed chair in 1948; it is during this period that his interests shift toward numerical analysis.

He was a member of the redactional committees for Psychometrika, Numerische Mathematik, Linear Algebra and Its Applications, and was editor in chief of the SIAM Journal on Numerical Analysis.

He opened up his wide personal bibliography on numerical linear algebra in form of a KWIC index.
