Zerka Toeman Moreno (June 13, 1917 – September 19, 2016) was a Dutch-born American psychotherapist and co-creator of psychodrama.

[1] Her paternal grandparents were grain merchants who, like many other Jewish families of the time, left Warsaw to go to England when Zerka's father, Joseph Toeman (1887–1956), was still a toddler.

In 1931, when Zerka was fourteen, her parents moved to London to reunite with the rest of her father's family.

[3] The Zerka T. Moreno Foundation is involved in the exploration of the Morenean theory, which examines the complex dynamics of human interaction.

It engages in various initiatives including training, research, and educational programs conducted in diverse locations like Western Massachusetts, Lesley University in Cambridge, and Portugal.

It also provides a selection of training resources by Zerka T. Moreno, promoting the exchange of knowledge within these fields.
