Frederick Justin Almgren
Birmingham, Alabama, USA
BiographyFrederick Justin Almgren is really Frederick Justin Almgren Junior since his father was also named Frederick Justin Almgren. Frederick Almgren Senior worked for the Securities and Exchange Commission during World War II, then following that he set up a number of businesses. Frederick Almgren Junior's mother was Sarah Cone Wright who worked as a real estate agent. Frederick had a younger brother David, and a younger sister Linda. He attended elementary school in Chevy Chase, Maryland, then continued his schooling at Swarthmore, Pennsylvania, before completing his high school studies at Princeton, New Jersey.
Almgren was an undergraduate at Princeton University but he did not major in mathematics, rather his main topic was engineering and it was in that subject that he graduated in 1955. While he was an undergraduate he :-
... won three varsity track letters as a pole vaulter, sang in the Glee Club and directed its close harmony group, played in the marching band, and served in the Naval R.O.T.C.After graduating from Princeton, Almgren became an Officer in the United States Navy and spent three years on active service flying jet fighter planes with Attack Squadron 66. Jean Taylor writes in :-
He delighted to tell his graduate students stories about his flying days, including how he once flew his plane through the top of a tree and had a piece of wood in a wing when he landed.Another story from his flying days is told by Mackenzie in . Almgren flew into a thunderstorm:-
When he looked at his instruments, they showed he was flying upside down, but he was sure he was not. Nevertheless, he 'went by the book'. He rolled the airplane until the instruments said he was right side up (although he said he could then feel himself hanging by the straps that pilots belt themselves in with) and turned around to fly back out the direction he'd been coming in .... After a while he emerged from the storm - and there were the lights of Galveston below him. So, yes, the instruments had been correct. But it took him a while to reorient his sense of up and down and accept that he wasn't hanging by his straps.In 1958 Almgren entered Brown University to begin research in mathematics. However, he did not give up his attachment with the Navy for he joined the Navy Research Reserve at this time and served in that capacity for a further 17 years. At Brown University an exciting phase had just started with Wendell Fleming collaborating with Herbert Federer in geometric measure theory. Federer supervised Almgren doctoral studies and Almgren wrote a thesis The Homotopy Groups of the Integral Cycle Groups which earned him a Ph.D. in 1962. He published a paper of over 40 pages based on the work of his thesis in Topology in the year he received his doctorate. His time at Brown University had not been entirely devoted to mathematics, however, for he built a sailing boat which he then sailed.
After completing his studies at Brown University, Almgren was appointed as an Instructor in Mathematics at Princeton University. He held this for the year 1962-63 but then resigned the position so that he could become a Visiting Member of the Institute for Advanced Study at Princeton. After two years he returned to Princeton University where he was appointed an assistant professor in 1965. Already he had published three further papers: An isoperimetric inequality (1964); Three theorems on manifolds with bounded mean curvature (1965); and Mass continuous cochains are differential forms (1965). In addition he had written the short book Plateau's problem: An invitation to varifold geometry which was published in 1966. Laurence Young writes:-
Plateau's problem is understood, in this little book, in a somewhat different sense from that of a generation ago. The reasons for this are partly indicated, for readers with only an advanced calculus background, in terms of examples, illustrated by a series of rather beautiful diagrams in colour. The concepts to which one is led are those first introduced in the theory of generalized surfaces. The book limits itself to the special cases most directly relevant to the formulation of Plateau's problem by Reifenberg, Federer and Fleming.In 1968 Almgren was promoted to associate professor and then full professor in 1972. Following this he spent several periods at the Institute for Advanced Study, namely 1974-75, 1981-82, 1985, 1989 and 1992. Almgren was married twice. With his first wife Beverly Stewart he had two children; Robert who went on to become a professor of mathematics, and Ann who also became a mathematician working on computational fluid dynamics. Almgren's second wife was his first Ph.D. student, Jean Ellen Taylor; they married on 6 October 1973 (the year Jean was awarded her doctorate) and had one daughter Karen.
In  Jean Taylor writes about Almgren:-
Fred found joy in everything. He used every possible excuse for celebrations: birthdays of course, but also especially fast times in jogging, good grades of his children, a paper of his or mine accepted for publication, or even a paper just finished. ... The drawer by the side of his bed is that of a six-year-old kid, not a 63-year-old man. Among its contents are a gyroscope, two magnets, four coloured balls from Cheerios boxes, two magnifying glasses, a fishing lure, a Star Trek communicator button, and five pretty rocks.Almgren was diagnosed with bone marrow cancer in August 1996 and underwent a bone marrow transplant (donated by his sister) in Boston in September. After about a month in hospital he was released and appeared to be making an excellent recovery. However, in January 1997 he developed pneumonia and was readmitted to hospital. He died of complications which followed the pneumonia. White writes in  and :-
Frederick Justin Almgren, Jr, one of the world's leading geometric analysts and a pioneer in the geometric calculus of variations, died on February 5, 1997 at the age of 63 as a result of myelodysplasia. Throughout his career, Almgren brought great geometric insight, technical power, and relentless determination to bear on a series of the most important and difficult problems in his field. He solved many of them and, in the process, discovered ideas which turned out to be useful for many other problems.Almost certainly Almgren's most impressive and important result was only published in 2000, three years after his death. Why was this? The paper was just too long to be accepted by any journal. Brian Cabell White explains the background in a review of the book published in 2000 containing the result:-
By the early 1970s, geometric analysts had made spectacular discoveries about the regularity of mass-minimizing hypersurfaces. (Mass is area counting multiplicity, so that if k sheets of a surface overlap, the overlap region is counted k times.) In particular, the singular set of an m-dimensional mass-minimizing hypersurface was known to have dimension at most m - 7. By contrast, for an m-dimensional mass-minimizing surface of codimension greater than one, the singular set was not even known to have m-measure 0. Around 1974, Almgren started on what would become his most massive project, culminating ten years later in a three-volume, 1700-page preprint containing a proof that the singular set not only has m-dimensional measure 0, but in fact has dimension at most (m - 2). This dimension is optimal, since by an earlier result of H Federer there are examples for which the dimension of the singular set is exactly (m - 2). ... Now, thanks to the efforts of editors Jean Taylor and Vladimir Scheffer, Almgren's three-volume, 1700-page typed preprint has been published as a single, attractively typeset volume of less than 1000 pages.Let us record three comments by former Ph.D. students of Almgren. The first is by Frank Morgan (Ph.D. in 1977) :-
Some great mathematicians seem to work by incomprehensible brilliant leaps and insights, but in Almgren I found a comprehensible definition of intelligence: facing a question head on and faithfully persisting in overcoming every obstacle.John Sullivan (Ph.D. in 1990) writes :-
Fred's lectures and classes were always full of wonderful geometric insights and pictures. But his writing was often in the drier style that he must have learnt from Federer. ... Fred's advice on coauthorship was that it is always better to err on the side of generosity: this does nobody harm, and leads to rewarding and productive collaborations.Our third quote is from Jean Taylor (see ):-
When I'd come in feeling I was making zero progress, I always came out feeling much better, because lo and behold, the thing I was stuck on and the progress I was making on it were something worth doing.Fred Almgren received many honours for his outstanding contributions. He was an Alfred P Sloan Fellow in 1968-70, an Exchange Visitor at the Steklov Mathematical Institute in Leningrad in 1970, a John Simon Guggenheim Memorial Fellow in 1974-75, and Earle Raymond Hedrick Lecturer for the Mathematical Association of America in1975. He was elected a fellow of the American Association for the Advancement of Science in 1982, was awarded a medallion by Brown University in 1988:-
... in recognition of distinguished contributions to society through scholarship and professional activity ...and he received the Class of 55 Public Service Award from Princeton University in 1988:-
... for contributions to society beyond the bounds of occupation.Among his service we should mention he was an editor of three journals: the Journal of Experimental Mathematics, the Journal of Geometric Algebra, and Differential Geometry and its Applications. He administered the Geometry Supercomputer Project for the Geometry Computing Group and served on the American Mathematical Society Committee on Applications of Mathematics.
