$Ernesto Cesàro (Born: March 12, 1859 deceased: September 12, 1906) was an Italian mathematician who worked in the field of differential geometry. He wrote a book, Lezioni di geometria intrinseca (Naples, 1890), on this topic, in which he also describes fractal, space-filling curves, partly covered by the larger class of de Rham curves, but are still known today in his honor as Cesàro curves. He is known also for his 'averaging' method for the 'Cesàro-summation' of divergent series, known as the Cesàro mean. After a rather disappointing start of his academic career and a journey through Europe - with the most important stop at Liège, where his older brother was teaching mineralogy at the local university - Ernesto Cesàro graduated from the University of Rome in 1887, while he was already part of the Royal Science Society of Belgium for the numerous works that he had already published. The following year, he got a mathematics chair at the University of Palermo, which he kept until 1891. He settled in Rome, where he stayed as a professor at the Sapienza University until his accidental death, while trying to rescue his youngest son Manlio from drowning.$ Ernesto Cesàro	Cesaro's Equation	Fabian Cesbron	Cesbronite	Clyde Vernon Cessna	Cessna Aircraft Company
