They married, and she moved from New York to Roland Park's Edgevale Road.

After living in Baltimore for several years, she phoned the landscape painter Eugene "Bud" Leake Jr., who then was Maryland Institute College of Art's president, and asked if he had any graduate students to teach. She recalled being told later by the college president, "I hired you for your name, but I didn't know you would be good at it."

This led to Ms. Hartigan's association with MICA's Hoffberger School of Painting, where she helped elevate its program to a top listing in the U.S. News and World Report annual survey of educational institutions. "I am a mentor, not a teacher," she told The Sun in 1987. "I give [my students] the example of having devoted my life to art, of constantly creating and growing."

In the late 1960s she rented a large Fells Point building at the busy intersection of Broadway and Eastern Avenue. For many years she lived there.

In interviews, Ms. Hartigan said her marriage to Dr. Price was deeply fulfilling. But in 1969, he injected himself with a vaccine he was testing for encephalitis. He fell ill with spinal meningitis, a disease related to encephalitis that can cause severe mental deterioration, and began a slow decline. He falsified a scientific paper and lost his job.

Ms. Hartigan swallowed a bottle of sleeping pills when she realized how bad the situation had become. Dr. Price got her to the hospital in time. "It wasn't characteristic of me, I was boxed in. I couldn't leave, and I couldn't stay," she said in The Sun's 2006 interview.

In 1982, the year after Dr. Price died, Ms. Hartigan acknowledged that she was an alcoholic and sought help. "My physician said if I didn't stop drinking, I had only a couple of years to live," she says. She had her last drink in 1983.

"She was very proud of her sobriety," said Suzi Cordish, Maryland Art Place board chairwoman. "She loved fine food and was a fabulous cook. She set a beautiful table with Royal Copenhagen china and linen napkins."

"She brought an intensity to her teaching," said Rex Stevens, a former student who is MICA's chair of the drawing and general fine arts departments and her longtime studio manager.

In 2004, Ms. Hartigan moved to Baltimore County, off Falls Road, after a developer bought her studio and she developed hip trouble.

Plans for a memorial service are incomplete.

Survivors include a brother, Arthur Hartigan of Huntington Beach, Calif.; a sister, Barbara Sesee of North Brunswick, N.J.; and three grandchildren. Her son, Jeffrey Jachens, died in 2006. Her three previous marriages ended in divorce.
