April 9, 1924 – Oct. 17, 2013

Leo Paul Ziemianski, who flew in 62 combat missions in two wars as a member of the Air Force, died Thursday in his Williamsville home. He was 89.

Mr. Ziemianski’s careers in the military and as a chemist took him to Japan several times and behind the Iron Curtain in eastern Europe.

Mr. Ziemianski grew up in Buffalo, and joined the Army Air Forces after graduating from Fosdick-Masten Park High School.

His military career spanned two decades and included service in World War II and the Korean War, and as a reservist. He was awarded a Distinguished Flying Cross and retired as a major.

He enjoyed military reunions with the Saipan-based 73rd Bomb Wing, said his son, Wayne.

Mr. Ziemianski earned a bachelor of science degree in chemistry from the University of Buffalo in 1949, and worked at Union Carbide for 32 years, beginning in Tonawanda. His family moved to Yorktown Heights in the late 1960s while Ziemianski worked in Tarrytown, New York City, and Geneva, Switzerland. He and his wife, Irene, returned to Western New York in 1993, after his retirement.

His travel in Europe afforded him the opportunity to speak in Polish about silicone technology with his business contacts, which he enjoyed, according to a document he preapred about his life.

Mr. Ziemianski was a member of the Young Men’s Society of Resurrection.

In addition to his son and his wife of 65 years, the former Irene Kaminski, Mr. Ziemianski is survived by a daughter, Lynn C. Maunakea.

Services will be held at 9:30 a.m. Wednesday in Holy Mother of the Rosary Cathedral, 6298 Broadway, Lancaster.
