His eccentric and confrontational style did not earn him many friends and he had a difficult time finding work after his studies had ended. InCardano repeatedly applied to the College of Physicians in Milan, but was not admitted owing to his combative reputation and illegitimate birth. Eventually, he managed to develop a considerable reputation as a physician and his services were highly valued at the courts.

He was the first to describe typhoid fever. In he cured the Scottish Archbishop of St Andrews of a disease that had left him speechless and was thought incurable. The diplomat Thomas Randolph recorded the "merry tales" rumoured about his methods still current in Edinburgh nine years later. Cardano himself wrote that the Archbishop had been short of breath for ten years, and after the cure was effected by his assistant, he was paid 1, gold crowns.

Today, he is best known for his achievements in algebra. Cardano was the first mathematician to make systematic use of numbers less than zero. He published the solutions to the cubic and quartic equations in his book Ars Magna. The quartic was solved by Cardano's student Lodovico Ferrari. Both were acknowledged in the foreword of the book, as well as in several places within its body.

In his exposition, he acknowledged the existence of what are now called imaginary numbers, although he did not understand their properties described for the first time by his Italian contemporary Rafael Bombelli, although the necessary mathematical theory of fields was not to be developed for hundreds of years. In Opus novum de proportionibus he introduced the binomial coefficients and the binomial theorem.

Cardano was notoriously short of money and kept himself solvent by being an accomplished gambler and chess player. London, UK.

Little is known of the early years of Cardano's life, but it is said that he was a child in poor health. In his youth he became an assistant to his father, who opened the door to the world of mathematics with his teachings.

Although at first his father refused to allow him to attend university, he finally gave in with the hope that he would study law at the University of Pavia, but he opted for a career in Medicine. When the war broke out in the area and before the closure of the study center, he had to move to the University of Padua to complete his studies. During that time his father died and left him a small legacy, which Cardano squandered on his love of games of chance.

He was a brilliant but difficult student, being excessively outspoken, uncompromising, and critical. In he received his medical degree and submitted his application to enter the Milan Medical College, but was rejected three times with the excuse of his illegitimate birth. It is then that he decides to move to the small town of Sacco and practices medicine a few kilometers from Padua.

In economic problems continued and Cardano, pressed by debts, decided to return to gambling, which led him to end up pawning his wife's jewels and some furniture. Among their desperate attempts to improve their fortune, they moved to Milan and end up falling into poverty, being forced to enter a welfare home. However, a surprising turn allowed them to get out of that terrible situation, when the Piatti Foundation in Milan granted him the position of professor of mathematics that his father once held.

During that period he was able to treat some patients and was gaining recognition in the practice of medicine, although he was still rejection of the medical institution. He even published a book in criticizing it scathingly and judging the character of its members. Cardano's medical practice and some near-miraculous cases were so prominent that they earned him an excellent girolamo cardano invention by women and the admiration of many.

This served as a pressure factor for the Milan Medical College, which modified the clause of his birth and ended up admitting him inafter having rejected him three times. This marked a period, approximately six years, in which Cardano, knowing Tartaglia's method, dedicated himself to working and studying the solution of third degree equations. Between andafter resigning from his position as professor of mathematics, he also abandoned his studies and relapsed into his addiction to gambling, this time spending the whole day playing chess.

English novelist E. Forster 's Abinger Harvesta volume of essays, authorial reviews and a play, provides a sympathetic treatment of Cardano in the section titled 'The Past'. Forster believes Cardano was so absorbed in "self-analysis that he often forgot to repent of his bad temper, his stupidity, his licentiousness, and love of revenge" A chronological key to this edition is supplied by M.
