The Memorial Tournament is a PGA Tour golf tournament, founded 43 years ago in 1976 by Jack Nicklaus. It is played on a Nicklaus-designed course at Muirfield Village Golf Club in Dublin, Ohio, a suburb north of Columbus. The golf course passes through a large neighborhood called Muirfield Village, which includes a bronze sculpture of Nicklaus mentoring a young golfer; unveiled in 1999, it is located in the wide median of Muirfield Drive.  
One of the main features of the tournament is a yearly induction ceremony honoring past golfers. A plaque for each honoree is installed near the clubhouse at Muirfield; Nicklaus himself was the honoree in 2000.
The greater Columbus area is where Nicklaus was born, raised, learned the game of golf, went to college, and started his own family. It was his vision to create a golf club that embodied his personal and professional life and to create a golf tournament that would long represent his passion for tournament golf, and would give back to a community that has embraced him and the game. This was fulfilled in May 1976 with the first Memorial Tournament, two years to the day after the course opened at Muirfield Village. The par-72 course was set at 7,072 yards (6,467 m),  a considerable length for the mid-1970s.
Nicklaus signaled his intent to host his own tournament during Masters Week in 1966, when he spoke of his desire to create a tournament that, like The Masters, had a global interest, and was inspired by the history and traditions of the game of golf. He also wanted the tournament to give back in the form of charitable contributions to organizations benefiting needy adults and children throughout Columbus and Ohio. The primary charitable beneficiary of the tournament is Nationwide Children's Hospital.
The Memorial reached the height of its popularity in the 1990s having reached "sold-out" status, a first on the PGA Tour other than the major championships. For a variety of reasons, the event has started seeing ticket sales decrease during the last five years.
The Memorial Tournament is one of only four tournaments given "invitational" status by the PGA Tour, and consequently it has a reduced field of only 120 players (as opposed to most full-field open tournaments with a field of 156 players). The other three tournaments with invitational status are the Arnold Palmer Invitational, the RBC Heritage and the Charles Schwab Challenge. The Quicken Loans National also had invitational status until it was replaced by the Rocket Mortgage Classic for the 2019 PGA Tour. Invitational tournaments have smaller fields (between 120 and 132 players), and have more freedom than full-field open tournaments in determining which players are eligible to participate in their event, as invitational tournaments are not required to fill their fields using the PGA Tour Priority Ranking System. Furthermore, unlike full-field open tournaments, invitational tournaments do not offer open qualifying (aka Monday qualifying).
In June 2014, the PGA Tour approved a resolution to grant the winner a three-year exemption, one more than other regular Tour events and on par with winners of the World Golf Championships, The Tour Championship and the Arnold Palmer Invitational. 
The field consists of 120 players invited using the following criteria: 
- Memorial winners in the last five years or prior to 1997

- Up to four players selected by the tournament from among the money leaders from the other five Federation tours

- 1976: Roger Maltbie wins the inaugural Memorial Tournament in a playoff, defeating Hale Irwin with a birdie on the fourth extra hole. The playoff was a three-hole aggregate, the first of its kind.  Irwin and Maltbie halved the first two extra holes, so it effectively became sudden death for the third hole. On the 17th hole (second playoff hole) Maltbie's errant approach shot appeared headed for the gallery when it hit a stake, causing the ball to bounce onto the green, where both parred. Maltbie birdied the 18th hole to win the playoff.
