*The army of those who have made at least one definite contribution to mathematics as we know it soon becomes a mob as we look back over history; 6,000 or 8,000 names press forward for some word from us to preserve them from oblivion, and once the bolder leaders have been recognised it becomes largely a matter of arbitrary, illogical legislation to judge who of the clamouring multitude shall be permitted to survive and who be condemned to be forgotten.'*- -- Eric Temple Bell:

## Italy

##### Gerard of Cremona (c. 1114 – 1187)

Italian scholar whose calling was to translate Arabic scientific and mathematical papers into Latin, many of which themselves were translations of works originally written in Greek.

Some sources credit him for the mistranslation that led to the word sine, but this may be more reliably attributed to Robert of Chester, who appears to be earlier.

##### Leonardo Fibonacci (c. 1170 – c. 1250)

Italian mathematician.

One of the most important figures in the history of the development of mathematics.

Wrote the highly influential and important *Liber Abaci* in which he discussed the Hindu-Arabic number system and its practical applications.

Most famous for the Fibonacci numbers. The number sequence itself was known to Indian mathematicians as early as the 6th century, but it was Fibonacci's *Liber Abaci* which made them well-known throughout Europe.

##### Campanus of Novara (c. 1220 – 1296)

Italian mathematician, astronomer, astrologer, and physician who is best known for his work on Euclid's *The Elements*.
**show full page**

##### Antonio Maria del Fiore (15th century – 16th century)

Italian Renaissance mathematician, sometimes rendered as **Antonio Fior**.

A student of Scipione del Ferro, learned from him the formula for the resolution of the particular cubic equation $x^3 + px = q$, and boasted that he was the only one who could solve such equations.

Challenged Niccolò Fontana Tartaglia to a contest in 1535 to solve cubics, but was outclassed.

Some sources suggest that it was **del Fiore** who revealed to Gerolamo Cardano that the solution originated from del Ferro and not Tartaglia.

##### Piero Della Francesca (1412 – 1492)

Italian painter and mathematician.

Recognized as one of the most important Renaissance painters, but was also a creditable mathematician.

His surviving mathematical works concern such subjects as: the abacus; the five Platonic solids, and perspective in painting.

- Documented the rules for multiplication involving negative numbers.
- Pioneered the work on the understanding of imaginary numbers, using as a springboard Cardano's Formula for the solution of the cubic.
- Developed a method of solving square roots by an approach related to continued fractions.

##### Pietro Antonio Cataldi (1548 – 1626)

##### Lorenzo Mascheroni (1750 – 1800)

Professor of mathematics at Pavia.

Wrote *Geometria del Compasso*, published in 1797, in which he showed that any geometrical construction that can be made with compasses and straightedge can also be achieved by using only compasses. This had, however, already been demonstrated by Georg Mohr in 1672.

Published in his 1790 work *Adnotationes ad Calculum Integrale Euleri* a calculation to 32 places of the value of what is now known as the Euler-Mascheroni Constant. However, only the first 19 places were accurate. The rest were corrected in 1809 by Johann von Soldner.
