Anne Rost Mandenberg Sieber MD 1922-2016

Anne Sieber MD was a weaver. When we returned home from college or on visits in later years, my mother was often sitting at a very large loom, weaving blankets, towels and other textiles. She had other looms, such as the Navaho loom, but her keenest interest was in the materials, usually a linen, silk, or woolen yarn, or a Native American cotton. Dr. Sieber traveled extensively in the Middle East with her husband, a well-known pediatric surgeon in the Pittsburgh area, where she took a great interest in the colorful and lushly woven Oriental rugs found in the bazaars and villages that they visited. Her artistic talents expressed themselves in her other hobbies, including antiques and artifacts of Ancient Egypt.

Dr. Sieber's medical degree allowed her to conduct research with her husband at Presbyterian Children's Hospital, during the 1960s through the 1980s where she also was a volunteer. The products of her research were several articles published in scientific journals on the subject of surgical treatment of pediatric respiratory and digestive defects. During this time, she was a docent at the Carnegie Museum, Pittsburgh, and volunteered at the Bryn Mar/Vassar bookstore in Oakland. In later years she became a Stephens minister at Shadyside Presbyterian Church in Pittsburgh.

Anne Rost Mandenberg was born on September 15, 1922 in Chicago, Illinois, to Edmund Carl and Estelle Margaret Mandenberg. She earned a Bachelor of Arts degree from Michigan State University in 1944 and an MD degree from the University of Michigan Medical School, in 1948. She was a member of the Alpha Epsilon Iota sorority. She studied Anesthesiology at Boston City Hospital where she met William K Sieber, Sr, MD. The two doctors became engaged and were married on June 15, 1951. They made their home in Pittsburgh, Pa. where her husband was a pediatric surgeon at Presbyterian Children's hospital. Anne practiced medicine until 1953 when her first son was born. Anne was a loyal loving wife and a devoted and caring mother, who is survived by 3 sons-William K Sieber Jr (Cynthia) of Cincinnati, Oh; Frederick Edmund Sieber (Elizabeth); and Kurt DeLance Sieber (Barbara) of Rochester NY; and six grandchildren. The Siebers resided in Pittsburgh, Pa for 62 years, until they moved in 2013 to Baltimore to be near family.
