A monthly contest from the editors of RECORD asks you to guess the architect for a work of historical importance.

Clue: A steeply raked A-frame structure defines the tentlike interior of this cathedral and gives it a memorable silhouette—a crucial feature, given that it is located in an inland American city known for its lively architecture. Completed in the early 1960s, the cathedral was designed by a prominent Los Angeles architect whose work spans numerous styles and building types.
