From the New York Times obituary section:

After an academic career spent in near obscurity, he became an internet phenomenon during the pandemic by uploading talks he had given three decades earlier.

… Michael Sugrue would go on to teach Plato, the Bible, Kant and Kierkegaard to two generations of undergraduates, including for 12 years at Princeton, without ever publishing a book—an academic who hadn’t “really had a career,” as he toldThe American Conservative after retiring in 2021.

But that same year, in the depths of the pandemic, Dr. Sugrue uploaded his three-decade-old philosophy lectures to YouTube, where many thousands of people whose aperture on the world had narrowed to a laptop screen discovered them. His talk on the Stoic philosopher Marcus Aurelius, in particular, seemed to fit the jittery mood of lockdown, when many people sought a sense of self-sufficiency amid the chaos of the outside world. It has now been viewed 1.5 million times.
