Joseph F. Frederick, 61, a former partner in a family plumbing, heating and roofing business, died Friday at St. Agnes Hospital after a heart attack, five days after the death of his father.
Mr. Frederick's father, John M. Frederick, 90, died last Monday at the same hospital of complications after surgery.
A mass of Christian burial will be offered at 10 a.m. tomorrow at St. William of York Roman Catholic Church, Cooks Lane and Baltimore National Pike. His father's services were held at St. William of York last week.
Mr. Frederick, who lived in Hunting Ridge, was born in Baltimore and educated at St. Bernardine's School. He graduated from Mount St. Joseph High School in 1947.
He was a partner for many years in M. J. Frederick & Bro., a company founded in 1855 by his great-great grandfather, a tinsmith who came to the United States from Germany in 1848. The business was dissolved in 1985 at the death of his cousin and partner, Herman A. Frederick Jr.
Joseph Frederick was a member of the board of directors of Royal Oak Federal Savings and Loan Association. He was a member of St. William of York Church for 35 years.
Survivors include his wife of 38 years, the former Ivy M. Ohle; two daughters, Barbara Frederick and Catherine Frederick, both of Baltimore; and three brothers, John C. Frederick of Lakeland, Fla., Charles H. Frederick of Bethlehem, Pa., and Thomas Frederick of Ellicott City.
The family suggests that memorial contributions be made to the William J. McCarthy Sr. Scholarship Fund, 401 Kensington Road, Baltimore 21229.
