This obituary might add some information for you:
https://www.reddit.com/r/ValueInvesting/comments/1867de5/obi...Specifically, this paragraph is the general way I was thinking about:
"Munger’s hero was Benjamin Franklin, whom he admired for his curiosity, ingenuity and wit. Munger’s own common sense, biting humor, pathological bluntness and disdain for conventional wisdom made him a celebrity among investors"
For me, personally, it was the way that he lived his life, was extraordinary brilliant, a polymath, and changed multiple fields of study (investing and arguably behavioral psychology.) He has not only directly created jobs, as others have stated, of millions, but has also indirectly altered the lives of millions for the better. He is one of the greatest minds in investing and he freely educated millions on his methods.
At the same time, he had some incredibly rough times and bore it with grace. For me, setting this type of example is also noteworthy. There are also the small things -- people who have been around him, he's incredibly respectful on an individual basis, always showed up early, and in general, lived in a way that I aspire to living.
