“Drei, zwei, eins!” With a rousing countdown in German, Stephanie Stebich, the executive director of the Tacoma Art Museum, led a group ribbon cutting Saturday morning that officially opened the museum’s new wing, showcasing art of the American West and doubling the museum’s gallery space.

Erivan Haub, the German grocery store magnate who donated his family’s Western art collection to TAM and paid for the new wing with a $20 million gift, beamed from a wheelchair pushed by his wife, Helga, during the celebration.
