What Happened in History? Book

I read this book because some genealogical research had uncovered a number of relatives many generations ago who had died of tuberculosis, and I wanted to learn more about the disease. It was accessible, even funny at times, sometimes jarring in its colloquial and judgmental tones. It was tremendously informative, and I learned a lot about the disease and its history, pathology, and epidemiology. I wished it had described the disease, briefly, and succinctly, in terms of what caused it, how it progressed, etc. This was all pieced together from biographical sketches that were very interesting, but I found myself still seeking out Wikipedia and other sources to identify the causes, symptoms, and progression of the disease articulated succinctly.
