Our History

In Dulci Jubilo: Latin for "In Sweet Joy"

In Dulci Jubilo, Inc. is a non-profit foundation established in 1978 by one man with a vision: Ted Rosenkranz, who graduated from Berkeley High School in 1939 and spent much of his life in the merchant marine. Ted established In Dulci Jubilo, Inc. to enhance the quality of life in his community by encouraging, inspiring, instructing, and helping young people enrolled in Berkeley's pre-school, elementary, and secondary schools to develop values beneficial to the community.

Ted created In Dulci Jubilo, Inc. to encourage discussion, development, and adoption of values in the areas of ecology, ethics, aesthetics, health, and general education with the aim of enhancing each child's feeling of self worth, an appreciation and recognition of worth in others, and in the environment in which we live. Prior to his death in November 2001, Ted created an endowment fund for In Dulci Jubilo, Inc. so that administrative expenses for the organization are covered – 100 percent of all donations go directly to funded projects.
