Serving Altadena since 1935

The Altadena Historical Society (AHS) was founded in 1935. We gather, preserve, and share print and digital information about the people, places, and events that have shaped the Altadena community.

Your AHS membership dues and donations allow AHS to continue—and expand—our work in the form of quarterly lectures, collection archives, exhibits, research, publishing, community outreach and more.

AHS is one of the oldest volunteer groups in the community. Explore our website to learn about all we offer—then visit us at the Altadena Community Center.

Don't miss in the new exhibit…

"Inspired by the San Gabriels: Five Men and the Mountains," presents the personalities and accomplishments of men who dedicated their lives to charting, conserving and promoting the San Gabriel Mountains.
