Fernando de Helguero was born near Florence. He studied mathematics at the University of Rome. After receiving his licentiate degree in 1903,^[3] he taught mathematics while he studied natural sciences, biology, statistics, and biometry.^[1] He was an Invited Speaker of the ICM in Rome in April 1908.^[4] However, he died later the same year in the 1908 Messina earthquake.^[1]

His collected papers were published in 1972.^[5]
