Lawrence Cunningham first stumbled upon Berkshire Hathaway when he was researching a paper on corporate governance. Warren Buffett’s hands-off management style fascinated him and Cunningham ended up getting advice from the Oracle himself after he put together his first book, The Essays of Warren Buffett. It was a compilation of Buffett’s letters to shareholders arranged by topic and Buffett advised Cunningham to self-publish. Since then, he has attended 15 annual meetings and a good part of that was spent lugging his self-published book around with his nephew Justin. Cunningham’s latest book, titled Berkshire Beyond Buffett, delves into the sustainability of Berkshire’s unique culture.
