Gerard Joseph Jarosinski Sr, a retired contracting firm executive, died Saturday of congestive heart failure at Gilchrist Hospice Care in Towson. He was 91 and lived in Sparks.
Born in Baltimore and raised on Kenwood Avenue, he was the son of City Council member Simon P. "Sam" Jarosinski Sr., who represented East Baltimore, and Martha Kwiatkowski. He attended Holy Rosary School and was a 1944 graduate of Baltimore Polytechnic Institute. He later attended the Johns Hopkins University and took management courses at Cornell University.
Mr. Jarosinski enlisted in the Army's Air Forces after he graduated from high school. He was assigned to Chanute Air Field in Illinois, where he also qualified as a sharpshooter. He left military service in 1945.
After working for Baltimore City's Bureau of Surveys, he joined Baltimore Contractors on South Central Avenue in 1947. He began as a time keeper and worked his way up to cost accountant, field engineer, director of purchasing and vice president. He retired in 1990.
"He could do complex calculations in his head in seconds," said his son, Gregory Jarosinski, an Ellicott City resident. "He was fantastic with numbers. When I was a young driver, he knew how far I had driven his car by how much gas I had used."
During his decades with Baltimore Contractors, Mr. Jarosinski worked on the construction of the causeways for the 1952 Bay Bridge, the Edward A. Garmatz Courthouse in Baltimore and the Rayburn House Office Building in Washington, among other projects.
"Jerry was an honest, conscientious and friendly guy," said Victor Frenkil Jr., a retired steel firm owner who lives in Glyndon. "He was always trustworthy."
In 1974, Mr. Jarosinski was elected to the Baltimore Contractors board of directors. He was later named president of a subsidiary, the Empire Construction Co.
Mr. Jarosinski worked closely with his boss, Baltimore Contractors' president Victor Frenkil Sr., frequently picking him up in the morning so the pair could discuss business on their way to the office.
"Jerry was a hardworking person," said a friend, Brother Frank O'Donnell, a member of the Marianist order. "It speaks to his dedication and work ethic that he remained at one firm for so long. When he said something, you had his word."
He also said that Mr. Jarosinski had a competitive side.
"When he got involved in charity work, he would be serious. He would get a large team together to assure there would be a large sum raised," said Brother O'Donnell. "Gerry was also hospitable. He often shared his home and his goods."
"I also remember him trying to instill values in his children," Brother O'Donnell said. "He believed in family dinner, where he was at the table nightly."
Mr. Jarosinski also served on the old Civic Center Commission. In 1966, Gov. J. Millard Tawes appointed him as a commissioner of the State Accident Fund.
He was a member of the Baltimore Economic Development Commission, the National Association of Purchasing Agents, the Baltimore Building Congress and Exchange, the Engineers Club and the Greater Baltimore Chamber of Commerce.
He was also an active member and supporter of the Boys Scouts of America and the Knights of Columbus.
A golf player, he belonged to the Country Club of Maryland and the Hillendale Country Club. He also organized charity golf outings.
Mr. Jarosinski enjoyed reading Tom Clancy novels, family members said. A sports enthusiast, he was a regular at Baltimore Colts and Ravens games.
"My father was the ultimate family man and attended may of his grandkids' sporting events," said Gregory Jarosinski. "He arm-wrestled with them well into his 80s."
After he retired from Baltimore Contractors, Mr. Jarosinski worked at Johnson Controls in Baltimore County. He then joined his son, David Jarosinski, a Cockeysville resident, at his buisness, D & I Mechanical. He retired a second time five years ago.
After living in Homeland and Sparks for many years, Mr. Jarosinski resided in Oak Crest Village in Parkville.
A Mass of Christian burial will be held at 11 a.m. Thursday at the Catholic Comunity of St. Francis Xavier, 13717 Cuba Road in Hunt Valley, where he was an usher and greeter.
In addition to his sons Gregory and David, survivors include his wife of 68 years, the former Patricia Mary Frentz; two other sons, Gerard Joseph Jarosinski Jr. of Hayesville, N.C., and Patrick Jarosinski of Ruxton; two daughters, Rosemarie Murphy of Stuart, Fla., and Mary Carol Lamdin of Cockeysville; 17 grandchildren; and 12 great-grandchildren. A son, Douglas Jarosinski Sr., died in 1995. Another son, George Jarosinski, died in 2015.
