Charles Bradfield Morrey Jr. (July 23, 1907 – April 29, 1984)[4] was an Americanmathematician who made fundamental contributions to thecalculus of variations and the theory ofpartial differential equations.

Life

[edit]

Charles Bradfield Morrey Jr. was born July 23, 1907, inColumbus, Ohio; his father was aprofessor ofbacteriology atOhio State University, and his mother was president of a school of music in Columbus. His sisterMarion Morrey Richter was a composer and pianist. Therefore it can be said that his one was a family ofacademicians.[5] Perhaps from his mother's influence, he had a lifelong love forpiano,[6] even ifmathematics was his main interest since his childhood.[7] He was at first educated in the public schools of Columbus and, before going to the university, he spent a year atStaunton Military Academy inStaunton, Virginia.[5]

In 1933, during his stay at the Department of Mathematics of theUniversity of California, Berkeley as an instructor, he met Frances Eleonor Moss, who had just started studying for herM.A.:[8] they married in 1937[7] and had three children.[9] With summers off the family enjoyed traveling: they crossed theUnited States by car at least 20 times, visiting many natural wonders, and looked forward to theAMS meetings, held each year in August. They usually spent abroad theirsabbatical leaves, and doing so they visited nearly every European country, witnessing many changes succeeding during the period from the 1950s to the 1980s.[8]

Academic career

[edit]

Morrey graduated fromOhio State University with aB.A. in 1927 and aM.A. in 1928,[10] and then studied atHarvard University under the supervision ofGeorge Birkhoff, obtaining aPh.D. in 1931 with a thesis entitledInvariant functions of Conservative Surface Transformations.[11] After being awarded his Ph.D, he was aNational Research Council Fellow at Princeton, at theRice Institute and finally at theUniversity of Chicago.[7] He became a professor of mathematics atUC Berkeley in 1933, hired byGriffith Conrad Evans,[12] and was a faculty member until his retirement in 1973. In Berkeley, he was early given several administrative duties,[13] for example being theChairman of the Department of Mathematics during the period 1949–1954,[14] and being the Acting Chairman, the Vice Chairman and the Director of the Institute of Pure and Applied Mathematics at various times. During the years 1937–1938 and 1954–1955 he was a member of theInstitute for Advanced Study:[15] he was also Visiting Assistant Professor atNorthwestern University, Visiting Professor at theUniversity of Chicago andMiller Research Professor at Berkeley.[7] DuringWorld War II he was employed as a mathematician at theU.S. Ballistic Research Laboratory inMaryland.

Honors

[edit]

In 1962 he was elected member of theNational Academy of Sciences:[1] on May 12, 1965, he was elected fellow member of theAmerican Academy of Arts and Sciences.[2] From 1967 to 1968 he was president of theAmerican Mathematical Society.[16] On the fifth of June 1973 he was awarded the prestigiousBerkeley Citation.[3]Maull (1995a, p. 10) refers also that other honors were granted him, but she does not gives any further detail.

Tracts of his personality

[edit]

Kelley, Lehmer & Robinson (1989, p. 107) describe him as really very gifted for friendship, having a charmingsense of humor[17] and being continuously attentive for people, mathematics and musics. His human qualities are described as the complement to his ability in administrative duties and in scientific research:[18] as a confirmation of his skills in scientific research, alsoMaull (1995a, p. 10) states that he was one of the strongest workers inanalysis.

The Charles B. Morrey Jr. Assistant Professorship

[edit]

In 1985 his widow, Frances Eleonor Morrey, née Ross, established theCharles B. Morrey Jr. Assistant Professorship at the Berkeley Mathematics department, to honor his memory.[19]

Work

[edit]

Research activity

[edit]

Con l'opera di Morrey il metodo diretto del Calcolo delle Variazioni riprendeva il suo cammino ed i problemi esistenziali rimasti aperti trovavano soluzione.[20]

— Gaetano Fichera, (Fichera 1995, p. 21).

Morrey worked on numerous fundamental problems in analysis, among them, the existence ofquasiconformal maps, themeasurable Riemann mapping theorem,Plateau's problem in the setting ofRiemannian manifolds, and the characterization oflower semicontinuous variational problems in terms ofquasiconvexity. He greatly contributed to the solution ofHilbert's nineteenth andtwentieth problems.

Teaching activity

[edit]

Charles B. Morrey Jr. was a very effective teacher.[13] His book (Morrey 1962) was the forerunner of a sequence of texts on calculus and analytic geometry, written in collaboration withMurray H. Protter. According toKelley, Lehmer & Robinson (1989, p. 106) and toMaull (1995a, p. 10), these books have had a wide influence on both university and high school teaching of mathematics. Morrey was also a successful advanced level teacher and thesis supervisor: at least 17 Ph.D. dissertations were written under his supervision.[13]
