Katherine Bogdanovich Loker, an heir to the StarKist tuna fortune and a major philanthropist in Southern California, died Thursday at her Oceanside, Calif., home of complications of a stroke, according to a spokesman for the University of Southern California, her alma mater. She was 92.

Loker and her late husband, Donald, donated more than $30 million to USC. In 1977, they gave $15 million to establish USC's Hydrocarbon Research Institute. She also funded the $3.4 million Katherine B. Loker Track and Field Stadium and a $1.5 million acting fellowship to the USC School of Theatre.

She donated $7 million to the Richard Nixon Library in Yorba Linda, Calif., for a 47,000-square-foot addition that re-created the East Room of the White House.

Harvard University, her husband's alma mater, also benefited from her donations. She gave nearly $30 million to the school.

Katherine Bogdanovich was born in 1915 in San Pedro, a Los Angeles neighborhood, to Yugoslavian immigrants. Her father, Martin, was a tuna fisherman who founded what became StarKist Foods, one of the world's largest tuna fishing and canning operations.

She attended USC, receiving a bachelor's degree in English in 1940 and participating in track and field.

After graduating, she married her husband, who had a Hollywood acting career using the stage name Don Terry. He left acting to work for StarKist, rising to vice president of the company. He died in 1988.
