Matthew T. Kellermann, systems analyst

Matthew T. Kellermann, a computer systems analyst and lifelong baseball fan, died Aug. 1 of a heart attack at his Ellicott City home. He was 53.

The son of John L. "Jack" Kellermann, an American Telephone & Telegraph worker, and Ruth Bopp Kellermann, Matthew Thomas Kellermann was born in Baltimore and spent his early years in the West Hills neighborhood before moving in 1972 with his family to the Allenford neighborhood of Ellicott City.

A 1979 graduate of Mount Hebron High School, where he was an outstanding varsity pitcher, he studied for two years at the Community College of Baltimore County's Catonsville campus.

Before joining Lockheed Martin in 1985, he worked as a soil tester for an engineering firm. Until his death, he was working as a computer systems analyst in the defense contractor's Bethesda office.

Mr. Kellermann's love of baseball began when he was 6 playing in clinic leagues. He later played for the Edmondson Recreation Council teams, All Star, Hot Stove and American Legion teams.

"Matthew was a control pitcher with curveballs and sliders," said a brother, Mark Kellermann of Lutherville.

"He had a walk-on tryout with the Orioles, but since he was a better control pitcher than fastball pitcher, he couldn't hit the required 90-mph minimum to continue to the next level in the tryouts. He clocked out at 87 mph," his brother said.

Mr. Kellermann enjoyed vacationing in Ocean City, golfing, attending parties and watching sports.

He was a communicant of Our Lady of Perpetual Help Roman Catholic Church, 4795 Ilchester Road, Ilchester, where a Mass of Christian burial will be offered at 10 a.m. Saturday.

In addition to his brother and father, who lives in Ellicott City, Mr. Kellermann is survived by his wife of 22 years, the former Annette Hubble; a son, Adam Kellermann, a freshman at the University of Maryland, College Park; a daughter, Glynnis Kellermann, a freshman at Mount de Sales Academy; a sister, Mary Beth Norman of Ellicott City; and another brother, Paul Kellermann of Catonsville.
