Maria Catherine Walsh

CIA Officer, Volunteer

Maria Catherine Walsh, 87, a retired CIA officer, died of a heart attack May 17 at Virginia Hospital Center-Arlington. She had Alzheimer's disease.

Ms. Walsh retired from the CIA in 1975 after a 31-year career that started with its predecessor agency, the Office of Strategic Services. During that career, Ms. Walsh had many assignments and was among the first women to be named a CIA station chief.

"She kept better secrets than my father, and he was the head of Air Force intelligence," said her niece, Anne Walsh of Arlington.

Ms. Walsh, an Arlington resident, was born in Carbondale, Pa., and graduated from Marywood College in Scranton, Pa., in 1940. During World War II, she worked for the American Red Cross. She joined the OSS in 1944.

After her retirement, Ms. Walsh led the Diocese of Arlington chapter of the National Council of Catholic Women and was a member of a number of religious organizations, including the Sovereign Military Order of Malta, the Brent Society, the Arimatheans of Fort Myer and the SHARE Food Network. She also volunteered at the Poor Clare Monastery in Alexandria and was a docent at the National Shrine of the Immaculate Conception in Washington.

She had no immediate survivors.

Alan Dean Aaron

Orthopedic Oncologist

Alan Dean Aaron, 44, an orthopedic oncologist who last year outfitted a 12-year-old boy with an upper-arm expandable prosthesis, died May 14 at his home in Washington after a heart attack.

Dr. Aaron was one of only a few doctors in the Washington area who knew how to insert the prosthetic device called Repiphysis. In September, he successfully performed the procedure at Inova Fairfax Hospital on James Shirron of Arlington, who had a rare form of bone cancer. The device will lengthen as James's right arm grows.

In a Washington Post article about the procedure, Dr. Aaron said the technology could be a breakthrough for children with bone cancer. "It's pretty impressive what we've been able to do," he said. "Twenty years ago, it would have been a different story."

Dr. Aaron was born in Provo, Utah. He graduated from the University of Colorado in Boulder and received his medical degree from the State University of New York, Downstate, in 1986. He became a major in the Army Reserve a year later and worked as a doctor at Fort McClelland in Huntsville, Ala., and Fort Hood in Texas. He ended his Reserve service in 2001.

From 1992 to 1997, Dr. Aaron worked at Georgetown University medical school as a clinical professor of orthopedics.

Afterward, he began a private practice in Washington as an orthopedic oncologist. He would often provide free services for children whose parents could not afford the medical care.

For the past two years, he was director of oncology at Inova Fairfax Hospital, and since June, he had served as director of orthopedics at Suburban Hospital. He also was on staff at Sibley Memorial Hospital.

Dr. Aaron also wrote books used in medical training, among them, "Clinical Pathology of Soft Tumor Tissues" (1999). The book was updated in 2001 with new procedures. He was treasurer of the Washington Orthopedic Society and was recently elected to the board of trustees of Suburban Hospital. He was a member of the Cosmos Club and Blessed Sacrament Catholic Church in Washington.

Survivors include his wife of 15 years, Lynn Aaron, and their two children, Allister and Harrison Aaron, all of Washington; his parents, Marjorie and Joseph Aaron of Provo; and a brother.
