Patricia M. Hogan, 57, Realtor and activist

Patricia Mary Hogan, 57, of Rittenhouse Square, a Realtor and community activist, died Saturday of complications from a brain aneurysm at the Hospital of the University of Pennsylvania.

For more than two decades, Ms. Hogan sold condominiums and townhouses in Center City. She had been a top-selling agent for Prudential Fox & Roach for the last 17 years. She received the firm's Top of the Rock award in 2007 and last year received its President's Circle award.

"Patty was the kindest, most caring, selfless professional woman I ever met. She always put everyone before herself," said a Prudential colleague, Bill Lederer.

For more than 15 years, Ms. Hogan was secretary of the Friends of Rittenhouse Square, a nonprofit organization that works with the Fairmount Park Commission to preserve and beautify the six-acre square. She was active in Friends fund-raisers to purchase plants and bushes for the square, and helped initiate a successful bench program in the early 1990s.

For a donation, individuals purchased benches in the square. The Hogan family purchased a bench at her urging, said Ms. Hogan's sister, Judy Hogan-Wood.

Hogan-Wood said she had accompanied her sister one weekend when she was affixing donors' plaques to newly installed benches. Often, the donor purchased the bench in honor of a deceased loved one, and many touching stories were associated with the benches, Hogan-Wood said. "Patty knew them all," she said.

Ms. Hogan was an original donor to the capital fund for the Kimmel Center for the Performing Arts. After a friend was diagnosed with breast cancer, Ms. Hogan became involved with organizations fighting the disease.

She kept in close contact with several of her classmates from Bishop McDevitt High School in Wyncote. "Our children were her children," said a high school classmate, Lisa Bayard.

The daughter of a career Navy officer, Ms. Hogan grew up in Guantanamo, Cuba, and also lived in Pennsylvania, Florida, and Georgia as a youngster.

She lived in Glenside and attended McDevitt when her father was stationed at Willow Grove Naval Air Station.

Ms. Hogan earned a bachelor's degree from Kutztown University in 1973. She then worked for the Southeastern Chapter of the Red Cross of America and taught in Philadelphia public elementary schools for several years before embarking on a career in real estate with a condominium developer in New York City, Florida, and Houston. She returned to Philadelphia in the mid-1980s.

Ms. Hogan loved to travel abroad, especially to Italy with her longtime companion, Anthony DeSalvo.

She was devoted to her nieces and nephews, her sister said, and was attentive to her widowed father, Robert B. Hogan.

In addition to her father, companion, and sister, Ms. Hogan is survived by another sister, Monica Albus; brothers Robert and Michael; and 12 nieces and nephews.

A funeral Mass will be said at 1:30 p.m. tomorrow, which would have been Ms. Hogan's 58th birthday, at St. Patrick Church, 20th and Locust Streets, Philadelphia. Friends may call at 1 p.m. Burial will be in Calvary Cemetery, West Conshohocken.

Donations may be made to the Michael J. Hogan Jr. Fund, Box 36, Redondo Beach, Calif. 90277.
