BiographyEdwin Hewitt was the son of Irenaeus Prime Hewitt (1879-1961) and Margaret Guthrie (1889-1946). Irenaeus Hewitt, born in Lexington, Dawson, Nebraska to Thomas Jefferson Hewitt (1837-1886) and Fanny Augusta Rockwood (1842-1915) on 5 December 1879, was a Navy Supply Officer at Puget Sound Naval Yard who married Margaret Guthrie in Omaha, Douglas, Nebraska on 16 February 1915. Puget Sound Naval Yard had been established in 1891 and, during World War I, it constructed many ships to assist in the war such as submarines, minesweepers, tugs and ships designed to search for enemy submarines. He was a graduate of the Washington law college in 1904. Margaret, born in Cheyenne, Laramie, Wyoming to William Eugene Guthrie and Margaret S Hewitt on 19 April 1889, was a teacher of English to adults and a co-author of An outline of vocabulary building; a course for adult Americans. She had graduated at the University of Washington in 1911. Irenaeus and Margaret Hewitt had three children, William Guthrie Hewitt (1916-1983), Helen Margaret Hewitt (1918-1953) and Edwin Hewitt (1920-1999), the subject of this biography.
He described his own youth as follows :-
My early memories are for the most part happy, though I carry to this day recollections of stern discipline meted out for this or that childish crime. I suppose I was precocious, though by no means a prodigy. I learned mathematics and French with little effort. In grammar school I had a hard time with written arithmetic, though mental arithmetic and word problems were simple. At ten years of age I heard about logarithms, at thirteen about trigonometric functions. I was an insufferable child. I had - and still suffer from - a terrible habit of mouthing off.At the time of the 1930 US Census, the Hewitt family are living in Everett, Snohomish, Washington and Edwin's father is still working at the Puget Sound Naval Yard. Edwin, 10 years old at this time, is attending school. The family moved to Chicago where they lived at 5016 Ellis Avenue, Chicago. Edwin attended the Principia Academy, an Christian Science School in St Louis, Missouri, for three years :-
I had a marvellous mathematics teacher at Principia, Paul C Dietz. He gave me my head and the run of his exiguous mathematical library. I read trigonometry on my own, ditto Euclid (I loved ruler-and-compass constructions), built models of the regular solids, wrote out on tape an estimate of , found in Thornton C Frye's probability text, and enjoyed wielding a Keuffel and Esser log log duplex sliderule, which I still have. Of course, it is only an antique now. I had a fine teacher of French at Principia, Moniseur Robbins. He gave me a good start in French, and turned me loose to read 'Les Misérables' on my own: this was my first experience of reading a serious book in a foreign tongue. The Latin teacher at Principia was a Mrs Semple, a lady of the old school. We learned our Latin from her and much more about what the Germans called 'Umgang mit Menschen' Ⓣ.After Principia Academy, he spent two years at Leelanau School, a boarding school in Glen Arbor, Michigan. This school:-
... was founded in 1929 in Glen Arbor, Michigan by Skipper and Cora Beals and Major and Helen Huey as a for-profit college-preparatory school for students who wanted to learn in a Christian Science community.In 1936, when he was only 16 years old, he was awarded a scholarship to Harvard University. This was reported in both  and . The Harvard Crimson, 1 September 1936, records :-
Sixteen boys from high schools and private schools in the Middle Western and Southern states have been selected from among more than three hundred candidates in the area for scholarships to enter Harvard College this fall. The awards total $5,900. The boys, who were school leaders in scholarship and class activities, were chosen from an area including Ohio, Indiana, Illinois, Michigan, Wisconsin, Minnesota, Iowa, Kentucky, Missouri and Tennessee. The scholarships announced today went to ... Edwin Hewitt, of 5016 Ellis Avenue, Chicago, Ill., Leelanau School, Glen Arbor, Michigan.When Hewitt entered Harvard in 1936, George David Birkhoff was Perkins Professor of Mathematics and Marshall Stone was an associate professor :-
My six years at Harvard were happy. I melted into the crowd, no longer an underage, undersized misfit. The mathematics faculty was awe-inspiring. George David Birkhoff, an Olympian figure, was also dean of the Faculty of Arts and Sciences. William Caspar Graustein was a dignified man who always wore black three-piece suits. Edward Vermilye Huntington was an elderly scholar, plainly not part of the power structure. Joseph Leonard Walsh was greatly respected for his flawless lectures, though not for the Walsh-Rademacher functions: we had not heard of them. The younger faculty included David Vernon Widder, Saunders Mac Lane, Garrett Birkhoff, Willard van Orman Quine [I think he was in the Philosophy Department: he gave brilliant courses on mathematical logic], and Marshall Harvey Stone.Let us note at this point that we will quote from  on a number of occasions during this biography. A version of the whole article is available at THIS LINK.
We get some information about Hewitt from the 1940 US Census. The family at this time were living at 1354 East 47th Street, Chicago. Hewitt's father was an Assistant Personal director of the Candy Manufacturing Company and his mother was a teacher at a private school. Hewitt was awarded a first degree in 1940 and continued to undertake postgraduate studies for his Master's Degree which was awarded in 1941. Of course, World War II was now a factor in the life of any young man in the United States and Hewitt completed his Draft Card on 1 July 1941. His residence at this time was Kirkland House, Cambridge, Massachusetts. The Draft Card contains a physical description: weight 160 lbs; complexion light; eyes blue; hair brown; height 5 ft 10 ins; wears glasses and has a scar over his right eye. On 28 November 1941 he became a mason, joining The Harvard Lodge.
Hewitt undertook research with Marshall Stone as his thesis advisor. He submitted his thesis On a Problem of Set Theoretic Topology and was awarded a Ph.D. in May 1942. His thesis was published in the Duke Mathematical Journal in the following year. He gives the following acknowledgement:-
The writer is enormously indebted to Professor M H Stone for guidance in research preliminary to the preparation of this dissertation.The Introduction begins as follows:-
The present paper is concerned with the problem of determining under what conditions a topological space can be resolved into two complementary sets each of which is dense in the given space. A space admitting such a resolution is said to be 'resolvable'; a space (satisfying a certain restriction to be specified below) which cannot be so resolved is said to be 'irresolvable'. Several of the techniques made use of in obtaining a partial answer to this question have applications to other topological problems. We shall indicate such applications where they occur.He taught at Harvard for six months before undertaking war work as an operations analyst with the United States Army Air Force in 1943. He was flown to England to work at the Operations Research Station of the 8th Bomber Command in England, where he worked to calculate bomb trajectories and ways to defend bombers against German planes. While he was in England, his engagement was announced in the Boston Globe on 22 April 1943 :-
The principal construction, indeed, utilised in producing irresolvable topological spaces is a special case of an operation to which any topological space may be subjected and which we have named topological expansion. The first chapter is accordingly devoted to the development of a theory of such expansions. We investigate properties of spaces which are preserved under arbitrary expansions, giving in this connection a separation axiom of peculiar interest first stated by Urysohn. In considering various types of expansions, we prove the existence of a particular expansion enjoying a number of curious properties. This expansion, called a maximal expansion, is essential in the construction of irresolvable spaces. We also consider various properties of contraction, the operation inverse to expansion.
The second chapter contains a study of irresolvable spaces. The existence of irresolvable connected -spaces, totally disconnected Urysohn spaces, and totally disconnected completely regular spaces is proved directly from the expansion theory. Some irresolvable spaces enjoy a very strong disconnectivity property, which we investigate in detail.
In the final chapter, it is shown that, metric spaces, bicompact Hausdorff spaces, spaces satisfying the first countability axiom of Hausdorff, and various other special spaces are all resolvable. We also obtain a reduction showing that only -spaces, and in fact only bicompact -spaces, need be considered in dealing with the resolution problem.
Mr and Mrs Edward T Blanchard of Belmont, announce the engagement of their daughter, Miss Carol Blanchard, to Edwin Hewitt of Cambridge, son of Mr and Mrs Irenaeus Hewitt of Chicago, Illinois. Miss Blanchard is now a junior in the School of English at Simmons College. Mr Hewitt was graduated from Harvard in 1940, where he received his master's degree in 1941 and his Ph.D. in 1942. He is now on special duty abroad for the United States Army Air Forces.Carol Blanchard (1923-2001) had attended Belmont High School and then Simmons College. The College records her address as 79 Chilton Street, Belmont, Massachusetts and her "not-so-secret passions are mountains, mathematicians, pretzels, and poetry." The date of their marriage is given as 4 March 1944 but that does not quite work with the fact that Hewitt returned to the United States on 10 August 1944. He flew by Air Transport Command leaving from Prestwick, Scotland, going to the Pentagon, Washington D.C. Perhaps he crossed the Atlantic more than once in each direction. Edwin and Carol Hewitt had two daughters: Elizabeth Hewitt and Margaret Hewitt. Later, in April 1962, they were divorced and Hewitt married 30 year old Pamela Jones Meyer on 28 May 1964. They were divorced in October 1973.
After being discharged from the military in September 1945, he was awarded a Guggenheim Foundation award and spent the year 1945-46 at the Institute for Advanced Study at Princeton :-
There was a galaxy of eminences at the Institute for Advanced Study: Albert Einstein, Carl Ludwig Siegel, John von Neumann (who was around only part of the time) Hermann Weyl, Kurt Gödel, James W Alexander, Marston Morse. Richard Arens was Morse's assistant; Ernst Straus, Einstein's. At Princeton University there were Wedderburn (a man of small stature, no longer young, who wore well-cut tweeds), H P Robertson, L P Eisenhart, Salomon Bochner, Ralph Fox, Emil Artin, Solomon Lefschetz, Claude Chevalley. I was very much an 'Unterspieler' but enjoyed watching the big shots, attending their seminars, and observing their foibles. I was horrified one day to watch Chevalley bait Weyl like a terrier nipping at a water buffalo, while Weyl was trying to give a lecture on Lie groups.Hewitt taught at Bryn Mawr College for the year 1946-47, then moved to Chicago where he had two half-time jobs, one in the Department of Mathematics at the University of Chicago, the other on a military research project Chicago Ordnance Research. This move to Chicago was rather disastrous as he explained :-
I lost the military job by running afoul of the regular army colonel, Frank Fenton Reed, who was the Army liaison officer. I then found that Marshall Stone had no interest whatever in hiring me full time in his department. The man in charge of the Chicago Ordnance Research, Dean Walter Bartky, was decent enough about my plight but could do nothing to mitigate it. So I served out my one-year appointment in wretched circumstances.Three offers of jobs in the spring of 1948 saw him able to choose the one which looked most attractive. He accepted the offer from the University of Washington, pleased to go to Seattle, a place he had pleasant memories of from his childhood :-
I was taken with Seattle. We were welcomed by old friends from the 1920s, now rather grey at the temples. We found reasonable living accommodations. The department was a comfortable little group, which was for the most part unconcerned with research. Professors Z W Birnbaum (a Polish-born statistician), Ross A Beamont, and Herbert S Zuckerman rapidly became good friends. In particular, I found in Zuckerman a wonderful friend and collaborator. I learned most of my classical mathematics from him, a side that I had foolishly neglected in order to follow the sirens of functional analysis and set-theoretic topology. Herbert and I worked together from the autumn of 1948 until the day of his tragic and untimely death in June 1970. I am proud that my name stands alongside his, attached to now classical theorems in Diophantine approximation, the structure of semigroups, and abstract harmonic analysis.Hewitt spent the whole of his career at the University of Washington but spent time away on teaching visits, research visits and sabbatical leave: Uppsala, Sweden (1951-52), Australian National University, Canberra (1963; 1970; 1976, Mathematics Institute of Academy of Sciences, Moscow, Russia (1969-70; 1973; 1976), Erlangen and Passau, Germany (1975-76; 1986), the University of Texas (1972-73), the University of Fairbanks, Alaska (1982), Hokkaido University, Japan (1982), University of Passau, Federal Republic Germany (1986), University of Singapore (1988).
During March-May 1957 he was a visiting lecturer with the Mathematical Association of America. During this time, he gave the lecture The role of compactness in analysis on several different occasions. The lecture began :-
Analysis is an immense field of mathematics, and compactness concepts and arguments enter in a great many different branches of analysis. To give a really adequate picture of the role of compactness in analysis would require in fact a survey of much of analysis: a task obviously impossible of accomplishment within the confines of a short essay, to say nothing of the limitations of the writer. After some remarks about the concept of compactness as such, therefore, we shall give examples from various parts of analysis in which compactness enters as a necessary hypothesis. These examples range from highly elementary to fairly sophisticated. They have been chosen partly to illuminate the concept and partly as important theorems of analysis. No attempt has been made to be exhaustive.Hewitt wrote several influential books, both monographs and teaching texts; for details see THIS LINK.
W W Comfort writes about Hewitt's work in topology in :-
By any workable standard, Edwin Hewitt was a topological colossus. What is surprising, in view of the strong topological legacy he left us, is the paucity, in numerical terms, of his contributions. Even with a broad and generous interpretation of topology, one can classify no more than 10 of his approximately 103 research papers under that rubric. His definitive departure at the age of 35 from topological research in favour of harmonic analysis and locally compact abelian groups has been much noted and discussed by Hewitt-watchers and interested amateur historians. There were apparently two threads to this change of direction. My personal insight into the principal of these derives from the fact that Hewitt interrupted me 'sotto voce' on each of the two occasions in my life when he was in the audience and I was at the podium singing his praises. On the first of these, in October, 1982, when I introduced his Colloquium talk 'On a Theorem of F and M Riesz' at Wesleyan University, he asserted "I was prone to error in topology. I abandoned the field in 1948 plus epsilon." On the second, during my hour talk at the HewittFest at the University of Washington in 1988, when I drew special attention to the remarkable paper 'Rings of real-valued continuous functions I', he noted simply "There were errors in that paper." As to the second apparent motivation for the early career change of orientation, he declared himself publicly on the folly of his misspent youth: "I see little use for the elaborations of axiomatic topology. I had a rather severe case of the disease as a young man, but I'm happy to say it has been almost totally cured."One of Hewitt's best known results is the Hewitt-Savage zero-one law which appeared in his joint paper with Jimmie Savage, Symmetric measures on Cartesian products (1955). In this paper they note that their result:-
... was commented on by several who saw a prepublication copy of this paper. Blackwell, and Chung and Derman wrote us independently that they had become interested in the following question in connection with forthcoming publications. Is it true that the partial sums of a sequence of identically distributed independent random variables visit an arbitrary Borel set infinitely often with probability either 0 or 1? As they point out, the affirmative answer, which they had already demonstrated in certain cases, is an immediate consequence of Theorem 11.3 [the Hewitt-Savage zero-one law]. Halmos and Doob have shown us direct proofs, both of which make it plain that the theorem is close to and scarcely deeper than the ordinary 0-1 law. These proofs are, with their authors' permission, presented below.In  Hewitt writes that the main purpose of their 'zero-one' paper was:-
... a construction of measures on extreme points of a convex set that is a special case of what later became Choquet theory.Walter Schempp writes about Hewitt as a lecturer in  (see also ). Hewitt said:-
"The big secret I've learned the last few years is to love the students. I wish I'd learned it earlier." The standard material of lectures in analysis which he had offered so often to utterly different listeners he laid out before his students with his characteristic verve and explored it in lively dialogue with them, memorably spiced with little stories. "The only stupid question is the one that isn't asked." His ever friendly responsiveness to students should not be misunderstood: he did not compromise in the mathematical demands he made on them. "Exercises are to a mathematician what Czerny is to a pianist."Hewitt took on several important roles both in his own university and in the wider mathematical community. For example he was a member of the Mathematics division of the National research Council from 1957 to 1969, being on the executive committee during 1960-62 and 1967-69. He also served as a member of the United States National Committee for Mathematics from 1973 to 1977, being its chairman during 1975-1977. In the University of Washington he served as vice-chairman, then chairman, of the Faculty Senate during 1873-75.
Hewitt loved mathematics, music and, above all, travelling. After he retired in 1986 he continued his life of travelling and undertaking research. He found languages easy to learn and so had quickly learnt the language of the countries he had visited including French, German, Swedish, Russian, and Japanese. After retiring he started learning Chinese. Sadly his active retirement was short :-
In January, 1989, while attending a joint-meeting of the Mathematical Association of America and the American Mathematical Society in Phoenix, Hewitt suffered a massive stroke, which affected his speech, numerical abilities and other functions. Still, he continued to live alone and enjoyed entertaining friends. A subsequent stroke, along with other health problems, forced him into a nursing home, speechless and essentially unresponsive - the end of a good, long run.Deborah Tepper Haimo writes :-
Mathematicians are judged by their mathematics not their social graces, and some important mathematicians have been social misfits. Most, however, are rather ordinary people, socially. And a few are even very adept socially, collecting large numbers of friends, collaborators and pleasant adventures while still doing important mathematics. Edwin Hewitt is in this last group. His life ... shows that it is possible to enjoy life, enjoy people, and also enjoy and do first-rate mathematics.
