As I posted on this list some months ago, professor Dirk van Dalen
published a biography on Luitzen Egbertus Jan Brouwer (1881-1966).
Quite recently, Grattan-Guinness has reviewed this piece for the
_Bulletin of the American Mathematical Society_. I would like to
make it very clear that I am *just* informing listmembers that this
review has just appeared. Period. Please, do NOT infer from this that
I agree with most (or part) of what Ivor Grattan-Guinness states with
his proverbial style:
"The author draws much from the surviving _Nachlass_ originally
formed at his instigation and apparently still at his university
in Utrecht (p. vii); he also uses much information obtained from
contemporaries and contacts. Where necessary, manuscripts are
translated into English, but the original texts are not given, a
somewhat worrying point of scholarship. Brouwer's main publications
are given in a bibliography, though their locations in the *Works*
are not indicated; translations published elsewhere are also not
listed. Other primary and historical works are listed separately,
but here a significant lacuna emerges. The author refers only twice
to the reviewing _Jahrbuch \"uber die Fortschritte der Mathematik_
(pp. 130, 161), not even giving proper references to the reviews
involved; but much more is to be learnt from that source, as a few
examples below will hint.
"... some of [photographs] have reproduced rather darkly. This
is not the only culpability of the publisher: nobody there seems
to have copyedited the book before printing, so that the generally
excellent English is defaced by some infelicities of language and
slips in typing and formatting. The price, however, is top-drawer."
It goes without saying that I can also be quite *arrogant* if I want to...
But why? ...

Dear Colleagues,
As you already know, a brand new biography on Brouwer has just seen the
light through the eyes and pen of Professor Dirk van Dalen. To my request
he has kindly listed below the chapter titles, and has added a small
resume of the contents. Below I append his message for the benefit of
all interested readers.
Regards to all,
Julio Gonzalez Cabillon

L.E.J. Brouwer 1881 - 1966.
The biography deals with Brouwer's life up to and including his great
intuitionistic results, culminating in the famous theorem: all real
functions on [0,1] are uniformly continuous.
Brouwer's youth and student years are reported in some detail. The mystic
period and the intense activity of preparing the dissertation are covered
in detail. Indeed the germs of his later philosophy can be traced back to
his mystic views. The dissertation held the "first intuitionistic
program", in addition to work on Lie groups and geometry.
The topological work in the first period (1909-1913) is split into two
parts: the first part deals with 'elementary point-set topology' in the
style of Cantor and Schoenflies. Results from this part are, among others,
the fixed point theorem for a sphere, the theory of vectorfields on
spheres, indecomposable continua, the translation theorem. After 1909
the second period starts, the one based on simplicial approximation, the
mapping degree, etc. The best known results from that period are Brouwer's
fixed point theorem for n-dimensional balls and the invariance of
dimension-theorem, the invariance of domain-theorem. A by-product from
that period is the proof of the Continuity Method of Felix Klein. His
work brought him into unpleasant clashes with Lebesgue and Koebe.
The period closed with a general definition of dimension, including the
proof of the pudding: Rn has dimension n.
After this topological period the First World War interrupted Brouwer's
international contacts. During that period he returned to foundational
research, he also joined a psycho-linguistic philosophy project, the
Signific Circle.
In 1918 Brouwer returned to topology, while at the same time vigorously
developing intuitionism. His novel introduction of 'choice sequences'
revolutionized his mathematics and opened up the second and final
intuitionistic program. Hermann Weyl's contributions to intuitionism are
also discussed.
The life and actions of Brouwer form an integral part of the book. This
includes description of the artist communities Laren and Blaricum, where he
lived. Science affairs and international contacts (e.g. with Goettingen)
are given their proper place.
