The Westport-based Newman's Own Foundation has awarded a $750,000 grant to a nonprofit organization in Kenya that will double the size of a girls' school outside Nairobi, the foundation announced.

The grant to Kibera School for Girls will fund construction of a building housing 22 classrooms, Newman's Own said.

Founded by the late actor and philanthropist Paul Newman, the foundation has contributed nearly $1 million to the school's umbrella organization, Shining Hope for Communities, since 2010.

Besides the school, Newman's Own funding has gone toward health and sanitation services, and skill training provided to the people of Kibera through its Johanna Justin-Jinich Community Clinic and the Shining Hope Community Center.

"Shining Hope for Communities is a great example of an organization working within the community to effect change," said Robert Forrester, president of Newman's Own Foundation. "Our funding makes a difference primarily because of the organization's innovative approach to the complex problems of Kibera, and also because of the people of Kibera themselves, who are equal partners in these endeavors."
