Extractions: Rafael Bombelli 's father was Antonio Mazzoli but he changed his name from Mazzoli to Bombelli. It is perhaps worth giving a little family background. The Bentivoglio family ruled over Bologna from 1443. Sante Bentivoglio was "signore" (meaning lord) of Bologna from 1443 and he was succeeded by Giovanni II Bentivoglio who improved the city of Bologna, in particular developing its waterways. The Mazzoli family were supporters of the Bentivoglio family but their fortunes changed when Pope Julius II took control of Bologna in 1506, driving the Bentivoglio family into exile. An attempt to regain control in 1508 was defeated and Antonio Mazzoli's grandfather, like several other supporters of the failed Bentivoglio coup, were executed. The Mazzoli family suffered for many years by having their property confiscated, but the property was returned to Antonio Mazzoli, Rafael Bombelli's father. Antonio Mazzoli was able to return to live in Bologna. There he carried on his trade as a wool merchant and married Diamante Scudieri, a tailor's daughter. Rafael Bombelli was their eldest son, and he was one of a family of six children. Rafael received no university education. He was taught by an engineer- architect Pier Francesco Clementi so it is perhaps not too surprising that Bombelli himself should turn to that occupation. Bombelli found himself a patron in Alessandro Rufini who was a Roman noble, later to become the Bishop of Melfi.

Most notably, Bombelli helped engineer the reclamation of the marshes of the Val di Chiana which began, under Ruffini's patronage, some time prior to 1549. This project was suspended for some years between 1555 and 1560, and it was during part of this hiatus (15571560) that Bombelli did much of the algebraic work that ultimately became his book, Algebra , part of which was published in 1572.

Extractions: Previous (Alphabetically) Next Welcome page Rafael Bombelli received no university education. He was taught by an engineer- architect Pier Francesco Clementi so it is perhaps not too surprising that Rafael himself should turn to that occupation. Bombelli became an engineer and his several projects included reclaiming land. He worked for many years for Alessandro Rufini (later the Bishop of Melfi). His work included reclaiming the Val di Chiana marshes (1551-60) and, in 1561, a failed attempt to repair the Santa Maria bridge in Rome. Bombelli was the first person to write down the rules for addition and multiplication of complex numbers. He showed that, using his methods, correct real solutions could be obtained from the Cardan Tartaglia formula for the solution to a cubic even when the formula gave an expression involving the square roots of negative numbers. Bombelli wrote his Algebra in 1560, his only publication, a few years after

The Bombelli Page The truth about rafael bombelli. This makes, not JJ Sylvester, nor even BenjaminBanneker the first important mathematician in America, but rafael bombelli ! http://vax.wcsu.edu/~sandifer/bombelli.htm
Extractions: IHMT survivors: A number of you asked for the text of the talk that Dan Curtin gave at Mikatos on Thursday evening. Here it is. At the suggestion of V. Fred Rickey and Victor Katz, the Bombelli Team continued its epoch-making (or is it episteme-making) work in the History of Mathematics by addressing this new problem. You will be surprised where this led us. Last year, we clearly established Bombelli's Irish origins. The veterans among us will also recall that Rafael Bombelli was born under the name of Rafael Mazolli, but he had to change his name after some events involving treachery, intrigue and jealous husbands. So we searched the stacks of the Artemis Martin Collection here at American University and found Rafael Bombelli's personal diary for the years 1575 to 1577, and found that Bombelli had not entirely forsaken his given name, but had invested his original family's fortune in a margerine company, and used the profits to finance a trip to the New World. This makes, not J.J Sylvester, nor even Benjamin Banneker the first important mathematician in America, but Rafael Bombelli ! Moreover, while he was here, he also founded the city of Misoula, Montana, making that city the second oldest city in the United States, behind St. Augustine, Florida.
