put an end to the campaign. He then returned to Pavia, where he pursued his studies at the university under Francesco Brioschi, and determined to seek a career as teacher of mathematics. He graduated in 1853 as '' dottore negli studi di ingegnere civile e architetto''. Cremona is noted for the important role he played in bringing about the great geometrical advances in Italy. While, at the beginning of the nineteenth century, Italy had very little mathematical standing, the end of the century found Italy in the lead along geometric lines, largely as a result of the work of Cremona. He was very influential in bringing about reforms in the secondary schools of Italy and became a leader in questions of mathematical pedagogy as well as in those relating to the advancement of knowledge. The mathematical advances which Italy made since the middle of the nineteenth century were largely guided by Cremona, Brioschi, and Beltrami. His first appointment was as elementary mathematical master at the gymnasium and lyceum of

, and in 1866 to that of higher geometry and graphical statics at the higher technical college of Milan. In this same year he competed for the Steiner Prize of the Berlin Academy, with a treatise entitled ''Memoria sulle superfici del terzo ordine'', and shared the award with J. C. F. Sturm. Two years later the same prize was conferred on him without competition. As early as 1856 Cremona had begun to contribute to the ''Annali di scienze matematiche e fisiche'', and to the ''Annali di matematica'', of which he became afterwards joint editor. Papers by him appeared in the mathematical journals of Italy, France, Germany and England, and he published several important works, many of which have been translated into other languages.
