Which foundation was founded by the mutual fund pioneer John Templeton to promote spiritual discovery?

The foundation founded by mutual-fund pioneer John Templeton to promote spiritual discovery is the John Templeton Foundation.

Sir John Templeton established the foundation in 1987 after making his fortune as an investor known for seeking opportunities others overlooked. He directed the organization toward research into the “Big Questions” about reality, human purpose, morality, religion, and the relationship between science and spirituality.

The foundation funds interdisciplinary work rather than serving as a conventional denominational charity. Its programs have supported research in areas such as human flourishing, gratitude, free will, creativity, and the origins of the universe. Templeton also created the Templeton Prize, which recognizes major contributions to questions involving science, religion, and spiritual understanding.

Templeton Religion Trust is a separate organization, despite the shared family name and overlapping interests. The John Templeton Foundation is the canonical answer because it is the institution directly founded by Sir John Templeton in 1987.
