My father is a graduate of Harvard Business School. HBS's alumni association (not exactly sure if it's actually the alumni association, but I am guessing it is) creates a "profile" book for each graduating class of HBS every 5 or 10 years (any year that there is a class reunion).
At a minimum, the profile book contains each alumnus's name, the section they were affiliated with when they were a student at HBS and their current city/country of residence. Some people's profiles only contain the absolute bare minimum, other people have photos and very detailed entries about the various minutiae in their lives (career, family, etc.)
I flipped through the thing pretty casually, but some notable names that caught my eye:
Jamie Dimon
Mr. Dimon's profile only contained the bare minimum. His name, section at HBS, and current job title:
Chairman & CEO of JP Morgan
I guess when one becomes the head of a major bank on Wall Street, one simply can't be bothered to spend time on trivialities such as their business school's alumni profile book...
Stephen Mandel
Mr. Mandel was also another bare minimum profile. Interestingly, it appears he met his wife while they were both students together at HBS. There was a profile of a "Susan Zadek Mandel" which I assume is his wife.
Seth Klarman
Mr. Klarman was the opposite of Dimon and Mandel. He provided a recent picture of himself and wrote up a lengthy entry about Baupost plus some personal stuff such as the adjustment he and his wife are making to being empty nesters, what their kids are up to now (interestingly, Mr. Klarman's son appears to be a professional musician?), etc. All in all, he seemed like a very nice, down-to-earth guy who hasn't let his success/wealth get to his head.
Aside from these notables, however, the vast majority of people had profiles that were more modest. Obviously, not everyone can become CEO of a major publicly traded company or start their own successful hedge fund... It was not uncommon to see profiles such as "Senior VP of blah-blah-blah division at XYZ privately-held company"
It makes me wonder whether Seth Klarman would have still had the same level of success if he had not attended HBS. My guess is that with or without HBS, the end result would still be the same (Either way, he would still start and run a successful hedge fund). Or perhaps I am underestimating the amount of serendipity that is required to achieve success on the scale of Seth Klarman...?
