Keith Johnstone

Donald Keith Johnstone (21 February 1933 – 11 March 2023) was a British-Canadian educator and theatre director.

A pioneer of improvisational theatre, he was best known for inventing the Impro System, part of which are the Theatresports.

He was also an educator, playwright, actor and theatre director.

Donald Keith Johnstone was born in 1933 in Brixham, Devon, England.

He grew up hating school, finding that it blunted his imagination and made him feel self-conscious and shy.

After attending St Luke's College Exeter, he taught at a working-class school in Battersea, London in the early 1950s, before being commissioned to write a play by the Royal Court Theatre in 1956.

He subsequently became a play-reader, director and drama teacher there, where he chose to reverse all that his teachers had told him in an attempt to create more spontaneous actors.

In 1972, Johnstone moved to Calgary, Alberta to teach at the University of Calgary, where he remained until retiring in 1995.

Johnstone is featured in the book Blink: The Power of Thinking Without Thinking by Malcolm Gladwell.

Johnstone developed his training system at the Loose Moose Theatre, which he co-founded in 1977.

He wrote two books about his system; 1979's Impro: Improvisation and the Theatre, and 1998's Impro For Storytellers.

Johnstone's teaching was described as a reversal of the lessons he received as a child in postwar Britain.

Johnstone was married to Ingrid von Darl until their divorce in 1981.

They had one son, Benjamin Johnstone who had one son, Cort Dawnne, and Johnstone had a second son from another relationship.

He died at Rockyview General Hospital in Calgary on 11 March 2023, at the age of 90.

He retired as artistic director in 1998, but remained involved with the company and continued to work as an educator until 2018, amid a decline in his health.

Johnstone's work with performers comprised a vast collection of training games, exercises and lazzi.

Writing in The Guardian in 2009, Mark Ravenhill said about him, "Whereas his teachers told him to think more, he'll tell his students to think less. He was advised to plan a story before it was written. Now he says: listen to an audience and let the tale tell itself".

Johnstone was known for slogans that encapsulated his philosophy of improvisation, and included:
