The Event Horizon as a Vanishing Point: a History of the First Image of a Black Hole Shadow from Observation

"It’s just excellent. She’s Dutch but the thesis is in English—she went to a British university. She spent time with the people who imaged black holes. It’s about all the science images of black holes, and it’s very, very clear. Yes, definitely. I learned about them from her, from this thesis. It’s very, very good. I would recommend it over the other two books that are published. It’s not published, so it might be harder to get hold of. No. I had heard of them—everybody’s heard of them—but I wasn’t interested in black holes until I had to study them for the lecture. I worked on them for a couple of months, and by the time I gave the lecture, I was blown away by black holes. The lecture was well received, so I proposed a book on it. That was the beginning."
