Enrico Giusti died on March 26th, 2024, at nearly 84 years of age. I met him in November 1978 – a lifetime ago. And with him, a large part of my life is gone. There will undoubtedly be other occasions to remember him as a mathematician and a historian of science, fields in which Enrico left his own mark, a very important one. What I hope to do here is to weave together the threads of memory from more than forty years of exchanges and friendship.
