Robert Palmer Dilworth (December 2, 1914 – October 29, 1993) was an American mathematician. His primary research area was lattice theory; his biography at the MacTutor History of Mathematics archive states "it would not be an exaggeration to say that he was one of the main factors in the subject moving from being merely a tool of other disciplines to an important subject in its own right". He is best known for Dilworth's theorem relating chains and antichains in partial orders; he was also the first to study antimatroids.

| - Robert Dilworth (Hemet, 2 de desembre de 1914 - Califòrnia, 29 d'octubre de 1993), conegut com a Bob Dilworth per amics i familiars, va ser un matemàtic estatunidenc. Dilworth va estudiar a l'Institut Tecnològic de Califòrnia, en el qual es va doctorar el 1939 sota la supervisió de Morgan Ward. Des de 1939 va ser professor de la universitat Yale fins al 1943, quan va retornar a Caltech, on va fer la resta de la seva carrera acadèmica. El seu camp de treball va ser la teoria de reticles, tema sobre el que va publicar un llibre fonamental en col·laboració amb Peter Crawley: Algebraic Theory of Lattices (Teoria Algebraica de Reticles) (1973). També va publicar una trentena d'articles científics sobre el tema. A més de les seves activitats acadèmiques, durant la Segona Guerra Mundial va col·laborar amb la 8a Força Aèria i des de 1955 fins a 1976 va ser consultor de l'Agència de Seguretat Nacional. (ca)

Dilworth studierte am Caltech (Bachelor 1936), wo er 1939 bei promoviert wurde. Danach war er Instructor an der Yale University als Sterling Fellow. Ab 1943 war er wieder am Caltech als Assistant Professor. Während des Zweiten Weltkriegs war er Analytiker bei der U.S. Air Force in England. 1945 wurde er Associate Professor und 1950 Professor am Caltech. 1982 ging er dort in den Ruhestand. Neben seiner Hochschularbeit war er auch in der Schulausbildung für Mathematik aktiv, u. a. in einem staatlichen Komitee für die Collegeausbildung und einem Projekt zur Förderung der Ausbildung von Mathematiklehrern in Afrika. Dilworth arbeitete in der Theorie der Verbände (wo er wesentliche Beiträge leistete) und in Kombinatorik. Nach ihm ist der Satz von Dilworth benannt, aus dem u. a. der Heiratssatz folgt.

He is best known for Dilworth's theorem relating chains and antichains in partial orders; he was also the first to study antimatroids. Dilworth was born in 1914 in Hemet, California, at that time a remote desert ranching town. He went to college at the California Institute of Technology, receiving his baccalaureate in 1936 and continuing there for his graduate studies. Dilworth's graduate advisor was Morgan Ward, a student of Eric Temple Bell, who was also on the Caltech faculty at the time. On receiving his Ph.D. in 1939, Dilworth took an instructorship at Yale University. While at Yale, he met and married his wife, Miriam White, with whom he eventually had two sons. He returned to Caltech as a faculty member in 1943, and spent the remainder of his academic career there. Dilworth advised 17 Ph.D. students and as of 2020 has 635 academic descendants listed at the Mathematics Genealogy Project, many through his student Juris Hartmanis, a noted complexity theorist. Other notable mathematicians advised by Dilworth include Curtis Greene and Alfred W. Hales. (en)
