Allen Shields

Allen Lowell Shields (7 May 1927 to 16 September 1989) was an American mathematician who worked on measure theory, complex analysis, functional analysis and operator theory, and who is remembered as one of the world's leading authorities on spaces of analytic functions. He was a doctoral student of Witold Hurewicz. Over his career he directed a large number of doctoral dissertations, among them the 1967 thesis of Theodore Kaczynski, the future Unabomber, titled Boundary Functions. He also served as editor of the Years Ago column of The Mathematical Intelligencer, and a special issue of that journal was dedicated to his memory in 1990.
