Charlie Munger's signature

Lawyer, investor and Warren Buffett's partner for 45 years. He said the way to wisdom is a "latticework" of models from every big discipline. Here it is: spin it, and tap any node.

Mental modelThe latticework

"You've got to have models in your head, and you've got to array your experience on this latticework of models."

Drag to spin · tap a node · filter by discipline

He got into Harvard Law without a degree, lost a son and an eye, built a partnership that beat the Dow four times over, then spent 45 years teaching Warren Buffett to pay up for wonderful businesses. He died at 99, a month short of his hundredth birthday.

Six blocks from where Buffett would grow up.

Age 0 – 17
  1. 1 January 1924

    Born in Omaha, Nebraska

    Charles Thomas Munger is born on New Year's Day. His father, Al, is a lawyer; his grandfather is a federal judge.

  2. 1930s

    Working at Buffett & Son

    As a teenager he works Saturdays at the grocery store run by Warren Buffett's grandfather, Ernest, for long hours and little pay. Warren later works there too. The two do not meet until 1959.

  3. 1941 · age 17

    Mathematics at Michigan

    He enrols at the University of Michigan to study maths. He never finishes a degree.

1943 – 1962

War, law and loss

Meteorology, Harvard, and the hardest decade of his life.

Age 19 – 38
  1. 1943

    Army Air Corps meteorologist

    Days after turning 19 he joins the Army Air Corps, which sends him to Caltech in Pasadena to train as a weather forecaster. He is posted to Nome, Alaska.

  2. 1948

    Harvard Law, without a bachelor's degree

    A family friend, former Harvard Law dean Roscoe Pound, helps him in. He graduates magna cum laude and moves to Los Angeles to practise law.

  1. 1953 – 1955

    Divorce, then his son's death

    His first marriage ends in 1953. In 1955 his son Teddy dies of leukaemia, aged nine. Munger later said he walked the streets of Pasadena crying. In 1956 he marries Nancy Barry Borthwick; between them they raise eight children.

  2. 1959

    Dinner in Omaha

    Back home to settle his father's estate, he is introduced to a 28-year-old investor named Warren Buffett. They talk for hours. Buffett tells him law is a poor use of his brain.

1962 – 1975

Wheeler, Munger & Co.

His own partnership, run from a Pacific Coast Stock Exchange office.

Age 38 – 51
  1. 1962

    A law firm, and an investment partnership

    He co-founds the law firm Munger, Tolles & Hills (today Munger, Tolles & Olson) and, with Jack Wheeler, the investment partnership Wheeler, Munger & Co. He stops practising law in 1965.

  2. 1973 – 1974

    Two brutal years

    The partnership loses about 31% in 1973 and again in 1974. Investors want out, and he winds it up in 1975, folding his interests into Blue Chip Stamps and, later, Berkshire.

Exhibit A · $1 in 1962

What a dollar became by 1975

Wheeler, Munger$12.60
Dow Jones$1.98

14 years at 19.8% a year versus 5.0% for the Dow, as Buffett reported in his 1984 essay "The Superinvestors of Graham-and-Doddsville". The figure includes the two years of roughly 31% losses: concentrated portfolios swing hard.

1972 – 2023

The partner

How he changed Buffett, and Berkshire.

Age 48 – 99
  1. January 1972

    See's Candies: paying up for quality

    Buffett, trained by Graham to buy cheap "cigar butts", balks at paying three times book value for See's. Munger pushes. See's goes on to send Berkshire about $2 billion in profit. "Charlie shoved me in the direction of not just buying bargains," Buffett said.

    "A great business at a fair price is superior to a fair business at a great price."Munger's idea, in Buffett's 1989 letter
  2. 1978

    Vice chairman of Berkshire Hathaway

    He holds the job for 45 years, sitting beside Buffett at every annual meeting and answering long questions with famously short replies.

  3. 1980

    Losing an eye

    A complication after cataract surgery costs him his left eye, and he is warned the other may fail too. He starts learning Braille, then decides he does not need it.

  4. 1977 – 2022

    Chairman of the Daily Journal

    He runs a small Los Angeles legal newspaper company for 45 years. Its annual meetings become a second stage for his views.

  5. 1997 – 2023

    Costco

    He joins Costco's board and never sells a share, praising its low prices and fair treatment of staff as a model of how to run a business.

The ideas

How he thought

Inversion, incentives and the psychology of human misjudgment.

Exhibit B · The inversion machine

"Tell me where I'm going to die, so I'll never go there"

Borrowing from the mathematician Carl Jacobi, Munger solved problems backwards: work out what guarantees failure, then avoid it. Pick a goal and invert it.

How to guarantee failure
    So, avoid that and do this

      Exhibit C · Incentives

      "Show me the incentive and I'll show you the outcome"

      His favourite example: FedEx could not get its night shift to move packages between planes on time. Lectures failed. Then it stopped paying by the hour and paid by the shift, so workers could go home once the planes were loaded. The problem disappeared. Switch the pay scheme and watch.

      Exhibit D · The Psychology of Human Misjudgment

      Exhibit E · The lollapalooza effect

      Why a Tupperware party sells so much Tupperware

      Munger's example. One tendency nudges you. Several acting together overwhelm you. Switch them on one at a time and watch the pressure climb. The numbers are an illustration of his point, not a measurement.

      Exhibit F · Three baskets

      Yes, no, or too tough?

      "We have three baskets for investing: yes, no and too tough to understand." Most ideas go in the last one, and that is fine. Sort these the way Munger might have. The answers are our reading of his stated rules, not his own verdicts.

      Pick a basket.
      Yes0
      No0
      Too tough0
      Exhibit G · "The big money is in the waiting"

      Why sitting still beats trading

      Two investors earn the same return before tax. One holds for decades and pays capital-gains tax once at the end. The other sells every year and pays as he goes. Same skill, very different result. Munger called it "sit on your ass investing".

      1. 2005

        Poor Charlie's Almanack

        Peter Kaufman collects his talks into a book that becomes a cult classic. A new edition from Stripe Press arrives in December 2023, weeks after his death.

      2. September 2008

        BYD

        Introduced by his friend and fund manager Li Lu, Munger persuades Berkshire to buy 10% of BYD, a Shenzhen battery and car maker, for about $230 million. By 2022 the stake is worth about $9 billion. Berkshire sells down from 2022 and confirms a full exit in September 2025.

        Munger Hall

        He gives $200 million to UC Santa Barbara for a giant dormitory he designed himself, with most bedrooms lacking windows. A consulting architect resigns in protest in 2021, and the university later drops the design.

      2. 2021

        Buying Alibaba at 97

        As chairman of the Daily Journal he buys Alibaba shares for its portfolio, a rare tech bet. He later calls it one of his worst mistakes.

      3. 28 November 2023

        Dies in Santa Barbara, aged 99

        He dies 34 days before his 100th birthday. "Berkshire Hathaway could not have been built to its present status without Charlie's inspiration, wisdom and participation," Buffett writes.

      His words

      Short, dry and usually right.

      Exhibit I · The bookshelf

      "I have known no wise people who didn't read all the time"

      Some of the books Munger recommended again and again, across the disciplines of his latticework. Pull one off the shelf.

      Exhibit J · In his own words

      Exhibit K · Ask Charlie

      Ask the vice chairman a question

      At Berkshire meetings Buffett would talk for minutes, then turn to Munger. Pick a question and get one of his real answers.

      "I have nothing to add."
      Epilogue

      "It's not supposed to be easy. Anyone who finds it easy is stupid."

      Munger left a fortune of about $2.6 billion, small next to Buffett's, partly because he gave so much away and partly because he cared more about being right than being richest. He left a way of thinking that is still being taught.
