John Leroy Ostberg

John "Jack" Leroy Ostberg, age 94, passed away peacefully at his home in Mt. Prospect on Wednesday, February 8, 2023. Loving husband of 68 years to Madonna Ostberg. Devoted father of Bonnie (Mike Mooney), Daniel, Brian (Joyce), Eric (Sarah), Arla (Brian Aranza), and Rene. Beloved grandfather of Shane, Rachel, Neill, Colin, Mischa, Rhianna, Skye, Ceira, Brandon, Gabi, Abbi, Ava, and Sonia. Cherished brother of June Wiese. Predeceased by his parents Irene and John "Trygve" Ostberg. Jack grew up in the Lakeview neighborhood of Chicago, where his family struggled during the hard times of the Depression. He was drafted into the Army and served overseas in Korea from 1951-53. After his war service, he began working at Teletype in Chicago, where he met Madonna Collins, the love of his life. They married in 1954, raising their family in the Dunning neighborhood of Chicago and later Mt. Prospect. Jack attended Wright Jr. College and Northwestern University on the GI bill while working to support a growing family. He built a successful career in international sales and marketing at Teletype/AT&T until his retirement in 1990.

Jack was a devoted and thoughtful husband, father, and grandfather who woke up early every morning for decades to pick up McDonald's coffee for Madonna. He loved the outdoors, introducing his children to his love for nature through countless camping and hiking trips over the years. His home is filled with books as he shared a passion for reading with Madonna and his children. Jack treasured his grandchildren who all adored him. He provided unconditional love and support to his entire family, no matter the circumstances, with a strength that knew no bounds. He cherished his many friends and loved organizing parties and gathering people together. An avid tennis player, he played with his local tennis group well into his eighties. He was an active member of the American Legion Arlington Heights chapter and was proud to make his Honor Flight in 2015 through the Veterans Network Committee of Northern Illinois.

Jack's kind nature, quiet smile, intelligence, and sense of humor will be missed by all who knew him.
