Notable comings and goings at the 101-year-old Baltimore Museum of Art. In April, the museum threw open the doors to its renovated Asian and African art galleries, followed in October by the opening of a new center for learning and creativity — the final pieces in a $28 million refurbishing that’s bringing new life to the renowned institution. But some good things must come to an end. In June, the BMA said good-bye to Doreen Bolger, who had headed the museum for 17 years. The search for her successor continues.
