Titolo: Faa` di Bruno:matematico, ufficiale, santo

Mi dispiace per chi non prende l'inglese, ma vale la pena di sforzarsi.
Faa di Bruno era un brillantissimo matematico del secolo scorso, oltre che
essere ufficiale del Regio Esercito (finche` non abbandono` le armi per la
tonaca), fondatore di un ordine religioso di suore e fatto santo nel 1988.
C'e' il classico libro di Messori, ma ,ancora piu` significativamente, mi
sono imbattuto in questa biografia cercando in un sito di storia della
Matematica organizzato dall'Universita` di St.Andrews (Scozia).
Gli intenditori (Forex) riconoscerenno un sacco di nomi famosi, posso solo
aggiungere che *Peano* e' stato un suo allievo.

********************************
Faà di Bruno studied at the Royal Military Academy of Turin with the aim
of making a career in the army. He began his education in 1841, then he
was commissioner in the army in 1847. However by 1853 he had decided to
leave the army and take up the study of mathematics. 
Faà di Bruno travelled to Paris where he studied at the Sorbonne under
Cauchy who [1]:- 
.. he admired, not only for his genius, but also for his religious
fervour and his philanthropy. 
At the Sorbonne he was in the same classes as Hermite. After graduating he
returned to Turin where he studied for his doctorate, which he obtained in
1861. 
In 1871 Faà di Bruno became a professor at the University of Turin, being
appointed to the Chair of Higher Analysis there in 1876. His most famous
mathematical work was one on binary forms which he published in 1876. This
became better known in 1881 when Max Noether published a German edition of
Faà di Bruno's work. 
However, Faà di Bruno had interests other than mathematics which took up
much of his time and undoubtedly prevented him undertaking more
mathematical research. After his time studying in the Sorbonne, Faà di
Bruno did much charity work on his return to Turin. 
At this time Faà di Bruno came in contact with Giovanni Bosco. Bosco had
been ordained a Roman Catholic priest in 1841 in Turin and began to work
there to help boys who came to look for work in the city. Bosco provided
boys with education, religious instruction, and recreation. He eventually
he headed a large establishment containing a grammar school, a technical
school, and a church, all built through his efforts. In Turin Bosco and
others founded the Society of St Francis de Sales in 1859. 
Influenced by Giovanni Bosco, Faà di Bruno was ordained a Roman Catholic
priest in Rome on 22 October 1876. Faà di Bruno founded a religious order
(Suore Minime di Nostra Signora del Suffragio) in order to direct and work
for girls gathered in a house (similar to those founded by Giovanni Bosco)
called Conservatorio del Suffragio. In order to provide work for the
girls, Faà di Bruno had the idea that they could train as typesetters. He
purchased a printing press and set up the Tipographia Suffragio. There a
number of mathematics books were published including one by Faà di Bruno
himself on elliptic functions. In 1898 the printing press was purchased by
Peano for 407 lire and he printed the Rivista di Matematica on it for
several years. 
Bosco was made a Saint on 1 April 1934. Already by this time there was a
movement to canonise Faà di Bruno and in 1955 the Sacred Congregation of
Rites officially accepted the claim for Faà di Bruno to be canonised. Faà
di Bruno was declared a Saint by Pope John Paul II in St. Peter's Square
in Rome on 25 September 1988. 
In [1] Faà di Bruno is described as follows:- 
Faà di Bruno was tall and not always well dressed, but he was simple and
good natured. He was of a solitary disposition and spoke seldom (and not
always successfully in the classroom). He cultivated music and was said to
be a good pianist.
