She is 71 years old, and she has no memory of his voice. But that was her father on the recording, and he called her his "Margaret Ann."
She was glad she was alone when she heard him speak, she said. It was just such a surprise. His voice was so clear, he sounded so much like the rest of his Catonsville family. He spoke slowly and gently. He sounded calm.
Sgt. Cody L. Wolf, a turret gunner, died when his plane was shot down over Germany on Jan. 11, 1944. It was just weeks after his holiday greeting had been recorded as part of a 1943 Sunpapers Christmas Show produced by the newspaper's war correspondents in England.
Margaret Ann Wolf Harris was just 17 months old.
"I have all the pictures and all the mementos, but they were like a silent movie to me," said the retired teacher, who still lives in her grandparents' Prospect Avenue house, where she and her mother moved when her father was called up.
"Now I have his voice," she said after hearing that Christmas show, rebroadcast last week for the first time — after 70 years — on WYPR-FM and on baltimoresun.com.
Earlier this year, Baltimore Sun research librarian Paul McCardell discovered a package from the publisher's vault, unopened for decades. It contained a pair of reddish vinyl recordings of a wartime holiday broadcast from England that featured more than 50 soldiers and women in the Red Cross from the Mid-Atlantic region.
The Sun arranged to have the recordings converted to digital and worked with students and faculty at Stevenson University to locate survivors, family members and any information about what became of the men and women in the broadcast.
The project was completed in time for a 70th anniversary broadcast on "Midday with Dan Rodricks" on Dec. 20.
"A friend came to dinner that Friday night and told me I had to listen, that my father was on that broadcast," said Harris. "But it didn't really sink in.
"Then a cousin called and said I had to listen to it, and he gave me the link." She sat down at her computer Saturday morning, alone, and listened.
"Then he said my name, and it was a shock," she said. "How many times do you hear your father say your name? I never had."
Harris then sent an email of gratitude to McCardell and multimedia editor Steve Sullivan at The Sun.
"I am the daughter of Sgt. Cody Wolf. Today I heard my father's voice for the very first time. You have sent me a very treasured Christmas present. There are no words to explain how I felt when I heard my father speak about me. I was only 17 months old when he was killed.
"I am 71 years old and today I was his 'Margaret Ann.' "
She remembers the family talking about the broadcast years later, and how astonished they were that Wolf had been chosen to send his greetings.
"He'd only been in England a couple of weeks," she said. "My uncle told my mother they would never pick him, not when there were guys who had flown 28 combat missions and had been there for two or three Christmases."
"I've been thinking a lot about Catonsville," Wolf tells the host of the broadcast. The conversations were scripted in advance for security reasons, so he sounds a little formal.
"My parents and my wife and our 16-month-old daughter, Margaret Ann."
In an article that ran in The Sun after the broadcast, Harris' mother said she was thrilled to hear her husband's voice. "He sounded so good," she said. Margaret Ann, she told the reporter, had been busy babbling to her father's picture during the broadcast.
