A Mass of Christian burial for Leonard J. Jakubowski, an engineering assistant at the Johns Hopkins Applied Physics Laboratory, will be offered at 9 a.m. today at the Roman Catholic Shrine of the Little Flower.
Mr. Jakubowski, who was 73 and lived on Juneway, died Monday at University Hospital of kidney and liver failure after being injured in an automobile accident Dec. 28.
He worked in the calibration laboratory at the Hopkins institution and most recently calibrated instruments for the U.S.-French Topex satellite scheduled to study the oceans in 1992.
He was on the Hopkins staff since 1987 but did work there earlier as a technician for a subcontractor, Consultants and Designers Inc.
Earlier, he calibrated instruments at the Martin Marietta plant in Middle River, where he started in 1951.
A native of Baltimore, he was educated at St. Casimir's School, the Polytechnic Institute, the Baltimore Junior College, now the New Community College of Baltimore, and the New York Technical Institute.
He is survived by his wife, the former Marie Kowalski; two sons, Ronald Jakubowski of Baltimore and Bryan Jakubowski of Atlanta; a daughter, Cecelia J. Durazzo of Joppa; a brother, Casimir Jakubowski of Baltimore; two sisters, Helen Harla of Timonium and Angela Markowski of St. Inigoes; and five grandchildren.
