Someone else will undoubtedly say it much better than I will here but one of us has to break the very sad news: Ross Anderson died yesterday.

His enthusiasm, his wide-spectrum intellectual curiosity and his engaging prose were unmatched. He stood up vigorously for the causes he believed in. He formed communities around the new topics he engaged with, from information hiding to fast software encryption, security economics, security and human behaviour and more. He served as an inspiring mentor for generations of graduate students at Cambridge—I know first hand, as I was fortunate enough to be admitted as his PhD student when he was still a freshly minted lecturer and had not graduated any students yet. I learnt my trade as a Cambridge Professor from him and will be forever grateful, as will dozens of my “academic brothers” who were also supervised by him, several of whom post regularly on this blog.

Ross, thank you so much for your lively, insightful and stimulating contributions to every subfield of security. You leave a big void that no one will be able to fill. I will miss you.

RIP
