Why the Name Farnam Street?

The early inspiration for Farnam Street stems from the profound insights of Warren Buffett and his long-time business partner, Charlie Munger. I learned more from studying these two than from my MBA.

As a tribute to them, I named the site after the address of their company, Berkshire Hathaway, located at 3555 Farnam Street.

Over time, we’ve come to affectionately refer to Farnam Street as simply ‘FS,’ but the guiding principles instilled by Buffett and Munger remain at the core of everything we do.

By sharing their wisdom and exploring the mental models they champion, we aim to help our community develop the clarity of thought and breadth of understanding that have made Buffett and Munger successful.
