Martha J Weiner Charitable Foundation
The Martha J Weiner Charitable Foundation was a private foundation based in Del Mar, California. Its 2021 filing is marked as a final return: the foundation reported that its board elected to dissolve it in 2021, distributed all cash and non-cash assets to domestic public charities, and was preparing final paperwork with the California Secretary of State. It therefore appears to have wound down and stopped grantmaking.
