Paintings by Renoir, John Singer Sargent and William Merritt Chase that have long been held in private hands will be the centerpieces of a new museum in Santa Barbara.

Basic instructions for the museum were revealed Wednesday in the last will and testament of art collector Huguette Clark, who died at age 104 last month in New York. The daughter of U.S. Senator William A. Clark, she had a 42-room apartment on Fifth Avenue full of art, books and musical instruments at the time of her death.
