All Heart: HP 8020A Cardiotocograph

The HP 8020A cardiotocograph was the world’s first non-invasive electronic fetal heart monitor, developed in a partnership between Division in Böblingen, Germany, and Dr. Konrad Hammacher, a German OB-GYN and professor of medicine. Though it was originally available only in the European market, around 1970 it became the first major Hewlett-Packard project to be imported to the United States after being developed overseas.
