Patch Adams is a 1998 comedy-drama film starring Robin Williams. Directed by Tom Shadyac, it is based on the life story of Dr. Hunter "Patch" Adams and the book Gesundheit: Good Health is a Laughing Matter by Adams and Maureen Mylander. The film was a box-office success, grossing over twice its budget in the United States alone; however, it was poorly received by most critics.

In 1969, Hunter Adams (Robin Williams) is a troubled man who voluntarily commits himself into a mental institution. Once there, he finds that helping his fellow inmates gives him a purpose in life and earns the nickname "Patch". Because of this he aspires to become a medical doctor and two years later enrolls at Virginia Medical University, being the oldest first year student. He questions the school's approach to medical care, and clashes with the school's Dean Walcott (Bob Gunton), who believes that doctors must treat patients and not bond with them as people. Because of this and other incidents, including a prank during a medical conference, he is expelled from the school, although he is later reinstated due to his methods actually improving the health of patients. Adams encourages medical students to cultivate relationships with nurses and learn their interviewing skills early, and argues that death should be treated with dignity and even humor.

Hunter Doherty "Patch" Adams (born May 28, 1945, in Washington, D.C.) is an American physician, social activist, citizen diplomat and author. He founded the Gesundheit! Institute in 1971. Each year he organizes a group of volunteers from around the world to travel to various countries where they dress as clowns in an effort to bring humor to orphans, patients, and other people.

Adams is currently based in Urbana, Illinois. In collaboration with the institute, he promotes an alternative health care model, not funded by insurance policies.

Adams had a difficult childhood. His father, an officer in the United States Army, had fought in Korea, and died while stationed in Germany when Adams was still a teenager. After his father's death, Adams returned to the United States with his mother and brother. Upon his return, Adams has stated that he encountered institutional injustice which made him a target for bullies at school. As a result, Adams was unhappy and became actively suicidal. After being hospitalized three times in one year for wanting to end his life, he decided "you don't kill yourself; you make revolution."^{[citation needed]}
