Adolf Berle was an American lawyer, diplomat, and writer who rose to prominence in the mid-20th century as an expert on corporate governance and finance. He was widely recognized and celebrated for his work, which had a significant impact on the way corporations were regulated in the United States.
However, despite his successes, Berle's career experienced a decline towards the end of his life, as his ideas fell out of favor and he became less influential in his field. This rise and fall of Berle's career suggests that celebrity is often fleeting and can be subject to changing cultural and intellectual trends.
In other words, even the most prominent and influential figures in a particular field can fall out of favor and lose their celebrity status as new ideas and perspectives emerge. This highlights the importance of constantly adapting and evolving one's ideas and perspectives in order to stay relevant and maintain influence over time.
