KOSIEWICZ, Zbigniew (Zbig) Tadeusz, 81, died on July 21, 2020, from complications due to Alzheimer’s disease in the presence of his loving wife and daughter in Cedar Park, Texas.

Born in Warsaw, Poland on April 28, 1939, he grew up amid the reverberations of World War II. His Catholic faith and opposition to Communism shaped his identity and values during his late teens and early 20s. In 1965, he traveled to the United States for the first time to work on a farm in Eden, Texas. He fell in love with the beauty and expansiveness of the Lone Star State.

In 1966, he married Sławomira Michalik on Christmas Day. After they immigrated to the United States in 1974, he worked as a computer engineer for the International Business Machines (IBM) Corporation for more than 25 years. He previously earned a Bachelor’s and a Master’s degree in electronic engineering from the Polytechnic University of Warsaw.

Zbig was a dedicated husband, father, and grandfather. He loved animals, languages, history, nature, and politics. He enjoyed Italian and French films, British comedies, and sports. He adored opera, jazz, bluegrass, and classical music.

After retirement, he traveled extensively and served as a financial supporter and volunteer for the nonprofit Wildlife Rescue & Rehabilitation in Kendalia, Texas. He was most appreciated for his humor and bouts of joyous dancing.

He is survived by his wife of 53 years, Sławomira Kosiewicz, of Austin, Texas; his two children, Holly Kosiewicz and her husband, Trey Miller of Dallas, Texas, and their sons Alden and Oliver, and Ashley Kosiewicz and his wife, Maya Levine of Cambridge, Massachusetts, and their daughter Mariella; his sister Barbara Gramadowska; and his two beloved cats Lottie and Emma.

Memorial services will be planned by Cook-Walden Chapel of the Hills Funeral Home at a later date when it is safe for individuals to congregate. In lieu of flowers, the Kosiewicz family requests donations to The Alzheimer’s Association. Information and condolences under “Find obituaries and services” at www.dignitymemorial.com.
