Klaus E Grossmann Editor

Klaus E. Grossmann (PhD, University of Arkansas, 1965; Hab., University of Freiburg, 1970) first discovered the work of John Bowlby and Mary Ainsworth while conducting ethological and experimental research at the University of Freiburg's Institute for Biology after receiving his doctoral degree. He was appointed Full Professor at Bielefeld University, Germany, in 1970, and began the Bielefeld Longitudinal Study in 1973. In 1977, he moved his laboratory to the University of Regensburg and started a second long-term longitudinal attachment study. Professor Grossmann's numerous publications include, most recently, a collection of John Bowlby's and Mary Ainsworth's key papers in German translation with commentary (coedited with Karin Grossmann).

Karin Grossmann (PhD, University of Regensburg, 1984) is a Senior Scientist in Psychology at the University of Regensburg, Germany. Dr. Grossmann's research focuses on longitudinal and cross-cultural research in attachment. Widely published, she recently coauthored (with Klaus Grossmann) a book based on the Bielefeld and Regensburg longitudinal studies. She also teaches and publishes on the applications of attachment theory and research in family matters.
