Person: Dilworth, Robert Palmer
Bob Dilworth was an American mathematician who worked in lattice theory.
Mathematical Profile (Excerpt):
 Caltech was to play a very important role in Dilworth's life, for it was the Institution that he was associated with for almost the whole of his career.
 At Caltech, Dilworth's doctoral studies were supervised by Morgan Ward.
 Dilworth obtained his doctorate in 1939 and was then awarded a Sterling Research fellowship to study at Yale.
 At this point Dilworth was back at Caltech and he was to remain there for the rest of his career.
 Back at Caltech, Dilworth was promoted to Associate Professor in 1945 and then full Professor in 1950.
 Let us now turn to Dilworth's research contributions.
 By the time Dilworth began his research, the motivation behind much of lattice theory was to develop methods to attack problems in group theory.
 The main topics in lattice theory to which Dilworth contributed are: Chain partitions in ordered sets, in particular his chain decomposition theorem for partially ordered sets; Uniquely complemented lattices; Lattices with unique irreducible decompositions; Modular and distributive lattices, in particular his covering theorem for modular lattices; Geometric and semimodular lattices; and Multiplicative lattices, where he studied, among other topics, abstract ideal theory, and the representation and embedding theorems for Noether lattices and rrrlattices.
 One important aspect of Dilworth's research was that he always attacked the big problems in lattice theory.
 Let us now turn to Dilworth as a teacher.
 Teaching and examining mathematics played an important part in Dilworth's career.
 Dilworth was Chairman of this Committee from 1957 to 1961.
 In addition Dilworth served on numerous other bodies concerned with the teaching and examining of mathematics.
 Finally we should say a little about Dilworth other than his mathematical interests.
Born 2 December 1914, Hemet, California, USA. Died 29 October 1993, California, USA.
