# Mark McCormack

Mark Hume McCormack (November 6, 1930 – May 16, 2003) was an American lawyer, sports agent and writer. He was the founder and chairman of International Management Group, now IMG, an international management organization serving sports figures and celebrities.

## Business career

After his Army discharge, McCormack worked as an attorney at the Cleveland law firm, Arter & Hadden. In the 1950s he helped organize one-day golf exhibitions for professionals around the United States. In 1960, McCormack founded IMG.
McCormack wrote several books, including The Terrible Truth About Lawyers and What They Don't Teach You at Harvard Business School, which spent 21 consecutive weeks at #1 on The New York Times Best Seller list. His annual publication The World of Professional Golf, first published in 1967, included an (unofficial) world ranking system. In his book What They Don't Teach You at Harvard Business School, McCormack tells a fictionalized story of a Harvard study in which the three percent of graduates who had clear, written goals earned ten times as much as the 97 percent who didn't have clear, written goals. McCormack and numerous motivational speakers, including Tony Robbins and Brian Tracy, have used various versions of this story in their presentations.

## Originated rankings for golf and tennis

The system used to calculate Mark McCormack's world golf rankings was adapted in 1986 to become the Official World Golf Ranking system, with McCormack chairing the rankings committee made up of representatives from all the major golf tours. McCormack pioneered a similar system for tennis rankings. McCormack met his second wife Betsy Nagelsen-McCormack, a two-time Australian Open doubles champion and a Wimbledon doubles finalist, while she was a business client. They married in 1986. The couple founded the McCormack–Nagelsen Tennis Center at the College of William & Mary, which houses the ITA Women's Collegiate Tennis Hall of Fame.

## Death

McCormack died at a New York hospital on May 16, 2003, age 72, from complications after suffering a cardiac event four months earlier that left him in a coma. His second wife, Betsy Nagelsen, their daughter, Maggie, and children from his first marriage to Nancy Breckenridge McCormack, Todd and Leslie, later shared $750 million, when the family's shares in IMG were sold.

## Honors

In July 2006, McCormack was selected for induction into the World Golf Hall of Fame in the lifetime achievement category and was inducted in October 2006. On January 23, 2008, he was also inducted into the International Tennis Hall of Fame. He was featured as one of the Forbes 400 Richest Americans in 1995, 1998, 2001.
