Emeritus Professor of Politecnico di Milano.

Arnaldo Brandolini developed his whole academic career at Politecnico di Milano where, as a Full Professor of Electrical Measurement from 1980 to 2002, held the chair that Angelo Barbagelata and Piero Regoliosi held before him. He retired in 2002, and in 2006 was appointed as Professor Emeritus. He passed away in the night between January 15 and January 16, 2017, a few days before his eightysenventh birthday.

Thanks to his innate curiosity and his bright and never satisfied mind, he was extremely well read in both science and humanities, though his bashful attitude did not make it fully apparent. Talking with him implied moving from measurement to philosophy, and from there to history and traditions of distant (in space as well in time) people within minutes, and, in the end, you left enriched.

He was blessed to spend the most productive part of his scientific career across the revolution caused, in the measurement field, by the application of the new digital signal processing techniques. He pioneered and somehow anticipated this revolution with articles that can still be considered as milestones. He was open to collaborations and was a bright interpreter of the multidisciplinary character of measurements, perceiving and even anticipating topics and problems that would have become relevant in years to come, such as measurements under distorted conditions.

He was a precious mentor to his students: his example taught them much more than his words and his writings, that represented a huge amount of material.

In times when the model of School that has highly contributed to make University great tends to be neglected, he succeeded in keeping the Milan School of Barbagelata and Regoliosi alive, assisted by his firm ethics, never shaken by the sirens of an easy and immediate benefit.

The school of measurement found a true leader in him, and his lesson and the great example he set will never be forgotten.
